Check Bitcoin Wallet Address Balance - Online Tool | BitRef

'''
A little backstory...
I'm a long time bitcoin enthusiast. Been keeping a close eye on things since before it hit $500. However, after I missed out on the major boom in a couple years back I pretty much stopped paying attention. Just recently I saw that BTC went from 3k to 7k and with the halving coming up figured now is as good a time as any to reinvest.
So I took $1000 and put it into an exchange. And then from the exchange I sent it to my old favorite bitcoin mixing service... BitMixer.
Anyone reading this probably know exactly where this is going... BitMixer has been shutdown since 2017 and there are now numerous fake websites out there. I fell for "bitmixer-io" .com
To be honest with you, it broke my heart. I sent .1111 BTC off and waited for confirmations. Once the transaction was confirmed I waited to see funds appear in my wallet... and I waited... and then I started to lose hope. That's when I started to see the obvious signs of the scam. The website listed BitMixer's real wallet address... which has of course been inactive since 2017. The wallet address I did send my money to has only had 4 transactions all in the past year.
This was quite literally the stupidest mistake I have ever made in my life. For so many, many reasons.
Anyone reading this, please be careful out there. I consider myself extremely careful with my money, my data, and my OPSEC, but this mistake only took me 30 seconds to make and now it can never be undone.

P.S. If anyone out there happens to be so fortunate that they can help me recover what I lost I would forever be indebted to you. I can provide as much proof as is needed to back up my story. I'm not out here begging but I am here praying that somehow this will work out in the end.

Here's how decentralised second layer implementations should work on top of Bitcoin Core

I am very excited for the growing usage of the Lightning Network and I certainly believe that it could make great changes toward how bitcoin is used; however, I do believe that there are better ways to implement a second layer.
The Lightning Network uses exclusive channels, but second layers should operate with one continuous channel. This may be hard to grasp, but hear me out.
Alice wants to send one singular bitcoin to Bob. Using SegWit, it would take about 20 minutes with a fee of 95 satoshis per byte to confirm said transaction. Obviously we know that sort of thing would never persist as a usable currency for a "rapid economy" as fast as fiat is today.
However, using an ideal second layer that is decentralised, these transactions can be transferred in a matter of seconds, especially if those running the second layer assume the burden of time and combine the fees.
If transactions are combined together and ran in a block-series format on a second layer, then the burden of time is shifted away from the user and the fees would be lowered. Additionally, a second layer of fees would be needed to exchange for those running the second layer.
Send multiple transactions to the network and then to the blockchain
Have server clients run a full node from Bitcoin Core and broadcast their presence to the network. Have an open-source protocol be added to their broadcast to prevent spam attacks and DDos.
Use a bitmixer open source to regulate how the server clients send the transactions to Bob. Use such a bitmixer to transfer funds to a decentralised middleman whose private key is encrypted. Server clients, who are decentralised, broadcast their diagnostics to the network as well, which would be correlated with the transactions. Clients who fail to broadcast their diagnostics in a consistent manner would be auto-booted by the network. The script protocol to connect the network includes a function to boot inconsistent clients. Alice can now transact with Bob without sending a private key. In a way, these clients who run the info on their own servers act as "miners" in a way.
Group all of the proposed transactions, including the Alice-Bob one, in a public series organised similarly like a blockchain. Have the script protocol (which the clients run) verify the consistency and use BitRef or blockchain.info to create another series block of "receipts", this is to not only double but triple verify the transactions.
For Alice to use said network and thus transact with Bob, her wallet would also need to be transferred to the network along with the proposal to transact, along with the diagnostic property makeup of such transaction. That would then be matched by the clients who run a script protocol to start the process of sending and verifying the funds. Once Alice's and millions of other transaction proposals are grouped and reach an agreed-upon size, they are sent to the Bitcoin blockchain en masse using the "sendmany" command in Bitcoin Core. All server clients who participated and whose consistency in diagnostic reporting has been checked would be granted a portion of the lower, combined fees by running another script protocol grouping those funds.
The double-run script protocol of processing the fees and sending the transactions to the blockchain would be run simultaneously in a block-like fashion, and multiple blocks could be run at once.
In this manner, millions could combine their fees together (if the MB isn't too big to run all st once, the clients can break it up) and transact in a matter of a few minutes with super low fees.
Also, this would ideally be run on a P2P network or on I2P with multiple VPN layer configurations.

The Top 9 Interesting Bitcoin Facts You Need To Know

Part of the reason people don’t want to use Bitcoin is that they don’t know enough about it. Well, our mission here at CoinSutra is to get everyone on the same page with regard to Bitcoin and cryptocurrencies. 1. The first Bitcoin purchase was for pizza. Did you know why May 22 is celebrated as Bitcoin Pizza Day?
Initially, when bitcoins were mined they were virtually worthless as it cost literally cents to buy a BTC.
But it was until 22 May 2010, when someone purchased something with bitcoins.
Seven years ago on this day, someone bought Piazzas with bitcoins and this purchase was a big deal because no retailer was accepting bitcoins at that time for goods and services.
On 22 May 2010, two Papa John’s Pizzas were exchanged by Laszlo Hanyecz for 10,000 BTC. This was the first official documented purchase of goods using bitcoins.
At that time, the worth of 10,000 BTC was $41.
At the time of writing this article, the worth of 10,000 BTC is around $25.8 million.
  1. The inventor of Bitcoin is a mystery.
Yes, that’s correct! The inventor of Bitcoin is still unknown.
Since the inception of Bitcoin in 2009, there have been several speculations about who the father of Bitcoin is.
The Bitcoin whitepaper was made open to the public under the pseudonym of Satoshi Nakamoto. The identity of “Satoshi” is still a mystery yet to be solved.
Amidst this confusion, there are some people like Craig Wright, an Australian entrepreneur, who in May 2016 claimed to be the inventor of Bitcoin. However, this guy, later on, turned out to be just another scammer.
He with his partner tried to pump a forked version of Bitcoin called Bitcoin cash and made a lot of innocent users lose their hard earned money. None the less, he bought a Limbo with all the scam money.
Some even suggest that Samsung, Toshiba, Nakamichi, and Motorola together created Bitcoin.
“Satoshi Nakamoto”: Samsung and Toshiba —- Satoshi Nakamichi and Motorola —- Nakamoto This anonymity has led to comments like“Bitcoin is a Ponzi Scheme,“ yet this buzz has not stopped BTC from growing.
Because the purpose of Bitcoin is to be a decentralized method of exchanging money, this anonymity is very healthy for the platform.
  1. Bitcoin is untraceable & Bitcoin is NOT untraceable.
When making Bitcoin transactions, your name/identity is not used in any form. Only your public address is available.
But…
The Bitcoin blockchain is a permanent ledger which is transparent. If anyone knows your Bitcoin public address, they can see how many bitcoins you hold and what transactions you have made.
It’s how the FBI was able to bust the owner of Silk Road.
If users of Bitcoin want to hide their public address or IP, it can be done by using services like Bitmixer.io or a VPN.
That said, this just makes it difficult to trace; difficult, but not impossible.
  1. If you lose your Bitcoin private key, you lose your bitcoins.
James Howells, an IT guy, lost 7,500 bitcoins in November 2013. While he was cleaning his desk at home, he threw away his hard disk containing the private keys of bitcoins which he had mined in 2010.
The realization dawned on him when he read the news of a Norweigan man who made a fortune by buying BTC at a low price.
He searched and searched, but could not find his hard disk.
At present, the worth of 7,500 BTC is approximately $19.4 million.
Without the private key, the funds are lost forever no one can use them.
Until this point in time, it is estimated that around 25% of all bitcoins have been forever lost.
  1. Bitcoins don’t grow on trees. Just like money, bitcoins also don’t grow on trees.
But unlike traditional paper money, you can’t touch, feel, or print bitcoin.
Bitcoins are mined on the blockchain network, and they come into existence when miners successfully mine Bitcoin blocks.
At present, the mining power of Bitcoin’s network is 300 times more powerful than the world’s top 5 supercomputers combined.
  1. There will only ever be 21 million bitcoins.
Bitcoin’s supply is finite.
There will only ever be 21 million bitcoins.
At present, 16.3 million have already been mined and are being traded. The last bitcoin will be mined in 2140. After that, no new bitcoins can be mined.
  1. You can buy a lot of stuff with Bitcoin. People always ask what you can buy with bitcoins.
But the real question should be:
What can’t you buy with bitcoins? Here are just a few of the goods and services offered:
Coffee at Starbucks Funeral items in the US Space travel with Virgin Galatic Order food with Bitcoin E-commerce with Purse.io Book a flight for BTC Buy a Tesla Car To find out more places where you can spend your bitcoins, see CoinSutra’s guide on “Where Do I Spend Bitcoin?“.
  1. Since 2008, Bitcoin has consistently been making a profit (except for 1 year).
Year Price at the Start of Year Price at the end of Year Growth in % 2010 $0.0015 $0.31 20566% 2011 $0.31 $6.18 1893.5% 2012 $6.18 $13.44 117.5% 2013 $13.44 $751 5487.8% 2015 $285 $435.7 52.8% 2016 $435.7 $952.5 118.5% 2017 $952.5 $2586 (To date) 171.57% Yes, I deliberately missed one year: 2014. In that year, Bitcoin prices plummeted, incurring a 62% loss to investors.
That happened mostly because of the MtGox hack in 2014. After that, the price dropped from $751 to $285.
The fear of a blockchain hack engulfed investors, but it was not the blockchain which was compromised. MtGox had several fatal and exploitable flaws.
But every other year, the price of Bitcoin has steadily increased.
  1. Bitcoin can’t be banned. Due to the nature of Bitcoin, there is constant talk about “banning” it. This hostility towards Bitcoin is because it works outside the jurisdiction of the traditional banking system.
However, the fundamental design is such that it can’t be banned, only regulated. As long as you have an internet connection and a Bitcoin wallet, you can engage in Bitcoin.
Nevertheless, many countries have tried to ban it, like Bangladesh, Bolivia, Thailand, and Vietnam (among many others). But there are some countries like Australia, Russia, Japan, and Venezuela which have made Bitcoin an official legal tender and are regulating it.
However, some countries like India and even the USA are unclear of their official policy regarding cryptocurrencies.
Try as they might, Bitcoin can’t be pushed away just because it threatens the financial power structure. This is the real beauty of Bitcoin.
Facts You Need To Know About Bitcoin Bitcoin is considered by many as the most revolutionary breakthrough of the 21st century after the internet.
Numerous cryptocurrencies have come and left after Bitcoin. Some called themselves “rivals of Bitcoin” while some complemented Bitcoin.
This is proof that Bitcoin and the blockchain are here to stay.
If you know more exciting facts about Bitcoin that I have missed in this article, then do let me know in the comments!!!

Guys please help. Just made a huge mistake with my blockchain wallet

Ok. I just made a huge mistake. I created a new blockchain wallet, but I entered the incorrect email address. I logged in and got the address for bitmixer to send my mixed bitcoins to, from that wallet that I now can't get into. The wrong email that I entered is a real email address, so someone just got my wallet identifier and I'm not sure if they can just reset my password and get into my wallet. Please please help me. $1k is so much money for me right now.

PSA: I have lost $3500 in a big deal, because of system failure in BitMixer.io

Here is the message to their technical support.
I accuse the BitMixer that in 2016 they still haven't created opportunity for a customer to specify a custom transaction fee for an outgoing transaction, which made at least 1 person (me) going broke.
I do know that this place is not intended to fix problems of centralized companies, and I do realize that choosing their service is my mistake. But I'm putting this here as a PSA to warn others, that some mixers have very wrong policies leading to heavy time loss.
Situation I have paid $0.4 fee when I've sent money to bitmixer, but when they have sent my own money back, they decided to spend only $0.13 causing hours of delay for my funds and the thousands of dollars being lost in a huge deal (because we depended on how fast that last 1 BTC will go through to our customer)
email to [email protected]
Take a look at txid: https://blockchain.info/en/tx/e870188fdb0343c86c433351a6e5a9564442bd2a05fefe877984d60250b694c9 - this is a transaction from your mixer to my wallet. I have lost big customer $3500 because you guys thought it would be good idea to pay only $0.13 for as a fee for Bitcoin network, leading to hours of my funds being locked in a Bitcoin network (between unconfirmed to 1 confirmation).
With such levels of responsibility taken, and such high volumes going through your mixer, you could take 10% from your customers, but increase that fucking miserable fee.
How miserable you should be to not take into consideration the fact that some people appreciate time rather than few cents. How miserable you should be to take away from me 0.01 BTC ($6) and not be able to spend at least $0.4 for a Bitcoin network? (I could pay you another $5 extra if you only let me increase that $0.13 to $0.4 - the fee which I used to sent money to your service - which been confirmed immediately by the BTC network) You freaks saving money on transaction fees while your customers suffering from losing hours of waiting. Are you serious, you gained a lot from spending $0.13 on an outgoing transaction?
Go to hell, losers. I will have no choice, but destroy your reputation on all forums if you keep doing the same mistakes in future.
Today I lost $3500 and this is not the first time I'm losing with you and other Bitcoin companies who still don't understand that they have responsibility not only for accepting money, but also for paying back properly.
P.S. after 1 hour of waiting, transaction is still not confirmed and I haven't received my funds yet

Bitcoin noob here, still kinda lost after reading FAQ

Hi everyone,
First of all, sorry if the questions that I'll be asking are redundant but I'm lost after reading bunch of different thread/FAQ.
So I'm from France and I'm looking to buy some bitcoins. After my reading, I hesitate between two websites : bitcoin.de and coinbase.com. Before making the purchase I'd like to know what is the best way to remain anonymous as much as possible. I've heard of bitmixer.io which seem to be an "intermediate" between my bitcoins and the wallet to which I'll send them. If I use this, is it "safe" to buy them directly with my credit card ?
Another foggy point for me is the "wallet", I mean what will happen once I buy coins ? Will I have an address in which they are stored ? is it safe ?
I'd appreciate some answer if possible and/or some help if anyone is willing to spend 5 minutes explaining this to me a little more.
Thanks a lot, and sorry again if those questions are posted often.

Mixing Bitcoins is VERY Important, and you CAN be anonymous

Those of us who have been around for longer than Bitcoin itself are pretty shocked by some of the stuff going on in the community. But we expected it. It's still hard to watch.
Many of you are new to Bitcoin and you think you know everything. You don't. Those of us who have been around are careful to change our identities often, and that prevents us from having any status in the groups. But it keeps us safe.
Because we have little status, however, it means most of you novices will ignore us. You insult us. You get offended by everything we say.
You might mistakenly believe that I give a fuck what you think about about me. I don't. The only reason I write here, or anywhere else, is because I believe in the distributed technology behind Bitcoin. And I especially believe in Bitcoin itself. So if I can help any of you to bury some of that arrogance and start using your brains, then we all win.
A SIDE NOTE
I just want to get this out there one more time. Mike Hearn and the people like him are trying to destroy Bitcoin. They are greedy, self-serving, political dicks who have lost sight of the reason why this technology exists. I don't care what he wrote or contributed. People like Hearn want Bitcoin centralized.
If you don't hear anything else I've said, pay attention to that statement. They want to centralize Bitcoin. Hearn even said we need to throw out core. That is fucking retarded, and if you don't see that, it's because you don't understand the technology.
I suggest you read anything and everything you can by Nick Szabo, and to a lesser extent, people like Peter Todd. They are brilliant, and they are the people who will save this circus, if it can be saved. But that depends on what you do. Yes you.
Also, the Blockchain Alliance is the most evil thing to ever touch this community. Again, if you don't understand that it ss because you aren't educated. Enough about all that.
MIXING
All we ever hear anymore is that the blockchain is not anonymous. That is only partly true. The rest is bullshit.
There are a few people who have accumulated millions of Euros worth of Bitcoin. Most of them are wise and have their money safely anonymized. But the rest of you are morons and you're going to get into trouble.
Agencies like America's IRS are building an arsenal of policies designed to force you to fuck up your use of digital currencies. And when you do, they will fine you, penalize you, and maybe even throw you in jail for tax evasion. If you don't believe me, look at that poor little bastard Charlie Shrem. And more recently, have a look at what's going on with the Coin.mx folks. They are trying to make examples of innocent people, and it's a shit show. If you don't believe me, again you're not paying attention.
Are you tender feelings hurt yet? Good. Down vote me. Ignore me. Report me to the moderators. You are obviously smarter than everyone else and I am just a fool. Go on and take your smart self out into the world and do your thing.
For those of you who care, you can and should anonymize your Bitcoin right now. You should also start focusing your attention and skills on supporting technologies that will make Bitcoin anonymity a one-click process.
For now, your best option is NOT centralized services like Bitcoin Fog, or Bitmixer.io. They are probably okay. Note, that I said "probably". But you have no way of knowing. And that's the scary part. Listen to what I just said. You have no way of knowing who owns those services and servers.
They are probably good guys, but if they aren't (if they are part of something like the NSA) and they decide to start a campaign, they could have all kinds of information about every transaction and address that has ever come through their services.
Bitcoin and blockchain transactions are only as public as their association with the owner of keys. That means if you open an account at ItBit, send them your passport, driver's license, physical address, social id, mother's maiden name, fingerprints, and shoe size, they're going to know with painful detail about every bitcoin you own.
But that doesn't mean you can't fix it.
WHAT CAN YOU DO NOW?
Before I tell you what you can do, you need to pay attention to some of the newer developments out there, like CoinJoin, Samorai Wallet, and especially a guy named Chris Odom. Soon, these people (or people like them) will build the technologies that will make Bitcoin truly anonymous. But you need to put your weight behind them. Yes you.
Until then, you should become aware of and use a service called Shapeshift.io. Shapeshift claims you're stupid if you try to hide from blockchain analysis. They're wrong. They're just trying to cover their asses.
Shapeshift allows you to transfer between Bitcoin and alts. You need to be aware that if you move Bitcoin to Litecoin and you think you've made your coins anonymous, then you really are stupid. You've just lengthened the trail and that is all.
But there is an alt that can make everything better for now, and it's Monero (there are probably others too, but Monero is the only one I've actually tested). If you take Bitcoins associated with your name, and move them into Monero, then create another Monero address, move the coins again, and them move them back to Bitcoin, they will be totally anonymous. Of course, this assumes you haven't transferred the new Bitcoins back to a wallet associated with you.
This is the part where you say I'm pushing Monero for my own financial gain. If you think that, fuck off. Seriously. Go fuck your idiot self.
THE PROBLEM WITH SPV
The best wallet on the market is Electrum, especially because it is the only wallet that I know of that allows you to have multiple multisig addresses inside a multisig wallet. I know there are cloud services that offer something like this, but I don't trust servers. Hopefully you get that by now.
Electrum has a flaw though. It is a SPV wallet. This means any server that you use to do a transaction gets every address in your wallet. In the real world, you're probably safe because the people running these servers are probably good guys. But again you don't know. And you never will
I will say it again, I don't trust servers, and this is a big flaw. I have asked the Electrum devs if and when they intend to address this, but the answers are vague at best. We should all be pushing this issue.
You can run your own Electrum server, but that's a huge pain in the ass, and most of you don't know how to properly set up a secure server anyway. I'm not even sure I trust myself to do something like that. The best solution would be for Electrum to fix this issue.
Armoury would have been an excellent choice, but it looks like they've stopped development. Also, if you use Armoury, you can only have one multisig address per multisig wallet. That's stupid, and they obviously don't intend to do anything about it if they've stopped development.
The solutions are coming, but we need to push for them. And if you just blow this off because you think it won't affect you, you're wrong, lazy, and arrogant. Of course we've covered that.
If you haven't down voted this already, go ahead and do it now. I'm an idiot, and I clearly don't have any idea what I'm talking about. But remember I'm trying to help you. If you don't like the insults, tough shit. My tone doesn't change the importance and truth of what I've said.
Best of luck.

A Plugin Framework for Litecoin Qt

Introduction

Litecoin provides an infrastructure for efficient payments and immutable data storage. While the infrastructure itself is revolutionary, we are still far from unleashing its full potential. Many more applications can be built around Litecoin. In order to facilitate easier application development and adoption, I propose a plugin framework based on the existing Litecoin Qt program.
Litecoin Qt is an "official" full Litecoin node with an easy to use graphical user interface (GUI) that can be used by those who are not technically savvy. It mainly functions as a Litecoin wallet to send and receive Litecoins.
As a wallet, Litecoin Qt does not really provide much advantage compared with lightweight wallets like Electrum-LTC. However, Litecoin Qt is the only available Litecoin full node with a nice GUI, and these properties make Litecoin Qt the ideal platform for supporting a plugin framework to host applications because many applications will need Litecoin blockchain data and an easy to use graphical interface to be suitable for normal users.
I list a few interesting example applications here and hope these will stimulate more ideas.

Example Applications

USDT

USDT is a token on top of Bitcoin blockchain and backed by USD. It is used by some major exchanges like Poloniex and Bitfinex. Technically, all data related to the token is stored on Bitcoin blockchain using OP_RETURN transactions. However, it is obvious that Litecoin is much more suitable for this job because of its much lower transaction fee and faster confirmation.
While USDT makes USD much more usable on the Internet, it does not really have an easy to use wallet. I think a plugin for Litecoin Qt that scans OP_RETURN data and finds USDT related transactions and makes OP_RETURN transactions to send USDT can become an easy to use wallet.
Many similar plugins depending on OP_RETURN transactions can be built. For example, a plugin can be used to send holiday (e.g. Valentine's day) wishes to the Litecoin blockchain, which thus lasts as long as Litecoin itself.

Efficient and decentralized CoinJoin

CoinJoin is an effective way for providing fungibility and anonymity to Litecoin users. CoinJoin services for Bitcoin are already available through centralized websites like https://bitmixer.io/ or decentralized standalone programs like https://github.com/JoinMarket-Org/joinmarket. While a decentralized program provides better anonymity and security, it incurs a cumbersome downloading and installation process, limiting its usage.
Compared with a standalone program, a CoinJoin plugin on Litecoin Qt is more available and much easier to install and use. Litecoins can be easily transferred from the Litecoin Qt wallet to the CoinJoin network for mixing and back to other addresses in the wallet with just one click.
Another advantage of making such a CoinJoin function a plugin instead of part of Litecoin Qt itself is that a plugin avoids potential legal issues. Some governments could potentially ban coins that provide complete anonymity within their protocol. Such a plugin avoids this issue and provides good anonymity and also keeps the Litecoin protocol simple.

Easier service consumption

Service providers like music streaming companies can provide plugins for users to easily pay for their services. Registration is not needed, and authentication can be done by automatically signing a token provided by the service provider using an address' private key in the wallet. Payments can be finished by simply clicking one button, and then Litecoins will be transferred to the service provider.

Implementation

Implementation of such a plugin framework requires a capable and secure plugin language. A good candidate is Lua. Lua is a widely used plugin language because of its easiness to embed, fast execution, and short learning curve.
Communication between the plugins and Litecoin Qt can be done through either Litecoin Qt's standard RPCs or C++ APIs specifically exposed by the plugin framework.
In order to forbidden plugins stealing wallets, plugins need to be sandboxed so that visiting local file systems (excluding locations for temporary files) should be disabled. While this is difficult for many script languages including Python, Lua can achieve it relatively easily. Beside that, only open source plugins shall be trusted until we have enough confidence on the framework's security.
This gives an example application with Lua plugins: https://john.nachtimwald.com/2014/08/16/extending-an-application-with-lua-plugins/. A Lua plugin for Litecoin Qt should be similar.

Bitcoin webwallets and KratomDelight: a bad complination (Coinbase warned about closing my account after marking my transaction to buy kratom as "high risk".)

This is for people looking to buy Kratom with bitcoin, feel free to ignore this post if you're not involved with bitcoin.
So about a week ago I sent KratomDelight some btc to buy few Grams from their Amsterdam shop. It's been almost a week since the order and today I received a message from coinbase similar to the following:
Your transactions seem to be in violation of our ToS [...] We realise Kratom isn't illegal in the US but it is illegan in many other jurisdictions [...] we consider such transactions high risk.
Note that the above is a shortened version of the email I received so I didn't quote word for word.
Here's what I suspect might have happened. Coinbase does indeed have strict ToS that get updated without notice. About a year ago they updated it to make "high risk and illegal transactions" against their ToS. Users taking part in such transactions could get their accounts suspended (meaning that all they could do is withdraw their funds and close the account afterwards).
While kratom doesn't exactly fit their criteria of "illegal transactions"(meaning they'd be illegal under US law) they still have the right to call transactions high risk if they feel like it. That's probably what happened to me.
If you're wondering how they were able to spot the transaction... Well, KratomDelight use the same bitcoin wallet address for all their transactions so it's extremely easy to identify transactions with the intention to buy from them. I'll contact kratomdelight later today about this. A solution from their side would be to generate a new BTC address for each customer. This would make tracing transactions significantly harder.
If you are using a Coinbase (or a webwallet with ToS restricting transactions) there are things you can do to avoid such situations too. Transfering your funds thtough a mixer like bitmixer.io to an unrestricted wallet (bitcoin core, multibit, electrum etc.) would make your coins untraceable to your webwallet service. You can then move them wherever you like without risking having transactions linked to you from your wallet service.
TL;DR: Don't buy Kratom using Coinbase as your wallet (likely the same issue would happen with Xapo, Cirlce and other web wallets as long as they have restricting ToS) or risk having your account shut down.
please excuse my bad English, It's my second language.

Internet's Largest Bitcoin Mixer Shuts Down Realizing Bitcoin Is Not Anonymous

This is the best tl;dr I could make, original reduced by 71%. (I'm a bot)
BitMixer, the world's most popular Bitcoin mixing service has announced last weekend it was shutting down operations effective immediately.
In a statement, the BitMixer owners said they were shutting down the service after realizing that Bitcoin was a "Transparent non-anonymous system by design."
This week - unrelated to the BitMixer announcement - Google and blockchain analysis firm Chainalysis announced they tracked down Bitcoin transactions for ransomware payments, even if the money was broken apart through Bitcoin mixers.
Almost all crooks use Bitcoin mixers to launder their ill-gotten Bitcoin funds.
Authorities, with the aid of private investigators, tracked the stolen funds to some of the BTC-e owner's Bitcoin wallets, even if those funds had been funneled through Bitcoin mixers.
BitMixer's announcement and subsequent shut down will be a cornerstone in Bitcoin's history, being the first mixer service that shuts down realizing its own uselessness and futility.

Bitmixer time?? Still haven't got bitcoins

Hey guys, so yesterday at around 8:00PM i sent some bitcoin from my electrum wallet to the address bitmixer gave me to be sent back to my electrum, and just now looked (9:35am the next day) and still pending. Checked the details on electrum and it says 0 confirmations. Has this ever taken this long for anyone? I have done this before and it worked just fine and only took like two hours though i think i set the time delay a bit lower.

How to properly "mix" bitcoins

Can someone explain to me how you would "mix" bitcoins with a service like bitmixer.io? On their website, they only allow you to enter a "forward address". Thats great, but how do I get MY bitcoins from my wallet to bitmixer.io to then be "mixed" and sent onto my receiving party? I for the life of me cannot wrap my head around this and I think I am missing something pretty silly here. Any help would be appreciated.

A SIMPLE GUIDE TO SAFELY AND EFFECTIVELY TUMBLING (MIXING) BITCOINS

Bitcoin tumbling, also referred to as Bitcoin mixing or Bitcoin laundering, is the process of using a third party service to break the connection between a Bitcoin address sending coins and the address(s) they are sent to. Since the Bitcoin blockchain is a public ledger that records every transaction, mixing coins is critical for anyone who doesn’t want the entire world to know exactly where they send and store their BTC, or from where they receive it.
Properly mixing coins may seem like a daunting task to those who aren’t very familiar with Bitcoin, but it is actually a simple process that will only take a few minutes of your time for each deposit.
There are good reasons for everyone to mix their coins, but for those who use Darknet Markets in particular, it is a necessity. New tools are being built all the time to increase the ability of the public, as well as private corporations and government agencies, to follow coins through the blockchain and track those who use it. It may seem like a waste of time now, but in the near future it may be simple for anyone- including friends, relatives, employers, and law enforcement, to track every Bitcoin transaction you’ve ever made and see exactly where it ended up. Breaking the connection between your addresses and the coins’ destination by mixing them is certainly a precaution that all DNM users should take.
In this guide we attempt to provide the simplest possible step-by-step instructions to help users unfamiliar with the process of Bitcoin tumbling do so effectively. This guide assumes the reader already has a basic understand of how to send Bitcoins and how to use .onion sites.
To mix your coins using this method, you will need:
-Bitcoins, or the ability to buy them. -The Tor Browser -The ability to create new Bitcoin wallets, both via Tor and on the clear net. We recommended using Electrum, but any client that functions over Tor will work. Alternately, you could use Blockchain.info and their Tor hidden service to create all or some of your wallets.
NOTE: Always make sure you get the .onion link for this and every hidden service from a safe place (like Darknetmarkets.org), never from Wikipedia, Reddit, or Hidden Wikis! Also make sure that you never use the blockchain.info clearnet url over Tor; doing that opens you up another possible vulnerability (malicious tor exit nodes). A good place to make sure you are using the correct URL is from our Darknet Resources page, or memorize our short link for it: drk.li/BC.
The Steps
Step #1: Create a wallet on the clearnet. (We will refer to this as wallet #1)
Step #2: Buy Bitcoins, and send the amount you want to mix to wallet #1.
Step #3: Create a second wallet, this time over the Tor network. (wallet #2)
Step #4: Send your bitcoins from wallet #1 directly to wallet #2.
The reason for this is to add plausible dependability between your clearnet wallet and in-person purchases. If you are ever investigated by law enforcement or the company from which you are buying coins (this happens with Coinbase.com especially), you can reasonably claim that you sent them to someone else who controls wallet #2 (for whatever made-up reason you have in mind as your excuse for your BTC purchase). After that you have no idea/don’t care what that person did with them, nor should anyone expect you to.
Step #5: Create a third wallet, also over the Tor network. (wallet #3).
Step #6: Select which mixer you will be using, and set up your transaction there using the address(s) from wallet #3. It is best to use multiple addresses, and to set random time delays.
ALWAYS MAKE SURE YOU ARE USING THE CORRECT .ONION LINKS!
Scams are rampant everywhere online, and the darknet is no different. You can choose your mixer(s) and get the correct URLs from our list of darknet Bitcoin mixers.
We recommend Helix by Grams first, and then Bitcoin Fog, as the two seemingly best in a group of imperfect options. They have both been extremely reliable so far while processing millions of dollars. DO NOT use blockchain.info’s shared send or any other coinjoin product as your mixer, as those do not completely hide your trail like the others.
Mixers in DarkNet:
braveb6iyacflzc2.onion - BraveBunny
btcwashzcpqktkwt.onion - Bitcoin Wash
m2cylfgzmxwauyqz.onion - BTCmix
bitmixegkuerln7q.onion - bitmixer
cleancondgqja34b.onion - CleanCoin
cleanco.in - CleanCoin
foggeddq65qveh2g.onion - BitcoinFog
blenderi54mbtyhz.onion - BitcoinBlender
grams7eo7mkagczs.onion - Helix Light
laundryzlzgnni4n.onion - BitLaundry
NOTE: Turn off JavaScript before doing this step if you are using Helix, Bitcoin Fog, Bit Blender, or other mixers that function without it. (Click on the “S!” icon before the address bar in the Tor browser, then >Forbid Scripts Globally”.)

Are my funds anonymous yet?

I bought a small amount of bitcoin using Coinbase, then I sent it to my Electrum wallet using Bitmixer. I'm very new to this (just started yesterday) so I apologize If I've overlooked something very basic.

Guys please help. Just made a huge mistake with my blockchain wallet

Ok. I just made a huge mistake. I created a new blockchain wallet, but I entered the incorrect email address. I logged in and got the address for bitmixer to send my mixed bitcoins to, from that wallet that I now can't get into. The wrong email that I entered is a real email address, so someone just got my wallet identifier and I'm not sure if they can just reset my password and get into my wallet. Please please help me. $1k is so much money for me right now.
