You are being used as money mule. You receive dirty money and provide clean money for a good profit.
If you get caught, ignorance is not an excuse and you may get jailed for doing this.
10% profit should be enough to know that there is something fishy about this deal.

^^This. Don't do it, OP. Someone's using you to launder. And guess who the authorities will catch first?  It ain't worth 10%. You're right to ask questions.

They don't market themselves as a mixer, but effectively that's what they offer. Their purpose is to obfuscate funds.

What "they" offer, is a privacy-orientated wallet. We have way too less of such wallets implementing new features and improvements.
CoinJoin is a decentralized way to regain some level of anonymity by mixing funds with other participants.

You are free to use your SPV wallet which communicates with a 3rd party server telling them all of your addresses, the amount of BTC you own, all your transactions, your IP address and therefore a relatively precise geo location.
But not everyone has to use such a privacy-invading wallet. And IMO wasabi actually is the best privacy preserving SPV desktop wallet available.


Yes, I agree. The mixer reference is not a negative connotation.

Wasabi is excellent. However, they're under investigation by Europol. Chainalysis did an 3-week investigation for them and according to their findings, 30% of the funds washed come from the dark market. Remember, this is similar to what happened to bestmixer.io before they got shut down.

Hi all,
just logged into my ledger to see a zero balance. I am not great at reading the blockchain transactions, could someone help?

I have 3 transactions I don't recognise.

First this one with 0.249 btc being transfered to me - https://blockstream.info/tx/a79f7ad72da35ea61731852efe39d3ace74dc7e92323a861581f31f01ddf1578
Second with me transfering 0.01 btc to another address - https://blockstream.info/tx/19af75549cecada158a77614c813361371adbb13e731a9c3ab3dc6ea0ee42fab
Third with me transferring 0.4499 btc to another address - https://blockstream.info/tx/a7cab7007fbee0e06d28e9635d442629ed4f0ec08af00453d56b305d8956387c

does this look like its been stolen? the third one seems to get split into many different addresses? I'm not sure if I'm reading it right. it's either this or I did the transaction and forgot where I sent it (unlikely). It confuses me why if this were being stolen, they would transfer 0.249 btc to me before stealing the balance

thanks for any help

I'm sorry this happened! I hope you've resolved the issue that led to the theft so it never happens again.

Your funds were sent to the mixer Wasabi wallet bc1qh6h8fxnldvm78gtpm00jjun5suwx2mn2jt7qm2 and commingled with 65 UTXOs--likely other victims. The funds were split into even transaction amounts--0.10791 BTC, with the exception of 1 output of 10.45923 BTC which was sent through the mixer again. There are hundreds of victims from what I can see. The funds are split from there; commingled; and sent to other private wallets and exchanges.

I'm not sure which hardware wallet you are using, but there is a clear exploit happening. You stated you made a mistake, saving the info--but I'd still contact the company and let them know what happened. They can't do anything, but you can raise their awareness and perhaps they can write a blog on how to protect private keys when using their wallet.

They don't market themselves as a mixer, but effectively that's what they offer. Their purpose is to obfuscate funds. And true, not ALL of the addresses are vics.

Ok--not an exploit--using this term liberally. Meaning, malware on OPs mobile exploited a flaw in OPs security.

I found this on Ledger's site: https://support.ledger.com/hc/en-us/articles/360005514233-Secure-your-recovery-phrase-PIN-code They do say never to take a photo of the 24-word recovery phrase. They have an "In the News" section where they highlight relevant information. A blog on security pinned to their front page might be a nice addition--Not everyone hops on forums, not every customer understands security. It's a kindness. Getting information out there is useful to the entire crypto community--we want this to succeed, I assume, and the community to grow. So do these companies. The more visibility/education on scams, fraud, security best practices--the better for all.

I hope this info is useful to you, OP. Again, very sorry this happened. Wishing you the best.

According to CipherTrace The cost of robberies, scams and fraud had already reached more than $ 4 billion by the end of the third quarter of 2019,

I'm not advocating crime, but has anyone ever seen a report that shows the estimated value of how many theft involving Hyip/ponzi sites have? What is the value of theft involving hyip/ponzi sites? Credit cards are also theft targets, this is not just a problem of the crypto world, it is a general problem. If there is money or anything of value, then scammers will be around. In the case of the crypto world people need to do more research on the projects that will invest money.

There are hackers everywhere, only that it is more common in these cases because we talk about ICOs, fraudulent airdrops on telegram, it is much easier to steal when the victim presses a link. and yes you should carefully review what to click, and what project you want to belong but some may be very well prepared with credible budgets but they are still scams, I say that the line is very thin, it is better be recommended by a person who verifies that the project is real



Old post, but just in case you still want the info:

It's because they use JavaScript. Even if you visit the clearnet link and disable JavaScript from your browser settings, you will get a blank page (Your Tor settings are probably set to disable JS).


So that means they are going against their own reccomendations on their "Step-by-step guide on how to mix your coins" article?

Quote
Assuming these coins are going to be sent to a darknet market… if you don’t already have your deposit address, sign in and get it while having JavaScript disabled. Never use any market that requires you to enable JS!


Regarding the reference to the dark market and the Russian evading state regulations example: MCM may be considered a money transmitter under FINCEN, which means they'd need a license:

https://cryptobriefing.com/bitcoin-coin-mixers-legal-crosshairs/

"Users of mixing services, however, need to be more vigilant. They are liable, according to FinCEN guidance, of being found to be intending to conceal the identities of funds or are, in fact, operating as transmitters. Transmitters need licenses. Concealing the identity of a sender or receiver of funds is a breach of the Funds Travel Rule if conducted by a registered financial institution.

While non-custodial wallet developers are not in breach of any legal obligation, those who use their software could be. The concern for those using mixing services is that in both the Harmon and Bestmixer cases, the enforcement actions were premised on the intent to conceal dirty Bitcoin.

Perfectly valid privacy-based grounds for mixing cryptocurrencies risk being swept up in the zealous delivery of law enforcement. Even if the primary purpose of this software is to protect people’s identities, there may be a tendency for law enforcement to assume these coins were ill-gained."
