For all those who might want to take advantage of the services mentioned by OP, keep in mind that the whole story may not be true - do not use unverified sites because instead of double BTC you may be left without a deposit.
Theoretically if you send with a very small fee, the funds will never arrive to the destination, the transaction will be reverted. So you can't be left without a deposit because the funds will arrive back, the worst you can have it blocked for a few days
Am I wrong?
Whoever made a mixer without protecting themselves from double-spend is far from a professional who knows what he is doing.
zxqmje462zmm6as2 with onion at the end is the said mixer. Is a service on tor browser . I think normal version can be accessed if one puts ws at the end
I write the address to show is a very graphical ugly and simple bitcoin mixer, so I assume the programmer or designer is laking skills, he din't even got some profesional template embedded in it, which makes me think he is also lacking skills on configuration of bitcoin node server and other stuff...
I tried it personally for a few transaction, and it worked, I got the bitcoins out from mixer before my payment confimed entering the mixer.
I guess that sadly many laws look at mixers more as crypto-money-washers than privacy tools.
That stated I guess it could be improbable to have LEGAL consequences because it's improbable mixer owner will self-report its activity just to denounce you
That sounds good.
But I would be personally worried about violent revenges if you do not hide your identity in a really effective way (which is soooo difficult in these days, especially if you haven't always cared about it, ideally since the beginning of times)

As the owner of the mixer seems to lack skills to properly configure the mixer, I doub't he is having skills to trace me. I plan to mix the coins elsewhere after I get it.
