don`t do that on deep web , you can be caught by police ...
True. But if you're careful enough to follow certain precautions, to help ensure true anonymity, then there should be nothing to worry about, in my own opinion. If you disable plugins like flash and javascript, as well as use a PC which you don't normally use connected to a VPN and Tor, then you will be safe.
your bitcoin(firts addres) sending to altcoin exchanger
trading in there profit, youre altcoin withdraw to another exchanger, trade in there withdraw to youre second bitcoin addres
and then mixer youre bitcoin , to mixer service, and then receive to bitcoin addres 3
youre bitcoin is very clean and can't trace again
Thanks for the advice, mate. That is a very common guideline to follow when ensuring anonymity within your exchanged coins. The only thing you would need to be careful though is to never do anything without a VPN, as it will expose your IP address and leave a trace of who exchanged the coins at a specific point in time.
The best way to do this would be, to follow your guidelines, in addition to use VPN and Tails OS to leave absolutely no trace of what you were doing.
Also, I've seen that a new mixing method called TumbleBit will be coming to Bitcoin, which will help ensure greater anonymity over traditional mixing services. I hope that this would turn out to become very useful once it becomes officially released. Just sharing my thoughts.
