you need to move all of those coins to new addresses (that only you have keys for) before the seller does.
You are correct about that. Our methods of doing business are more complicated than what I described there.
I wonder if you can prove that even if you really do have these bitcoins, how do you know for sure they were stolen out of an illegal products website??
I hear so many stories of BTC stolen from regular peoples accounts cuz the hacker hit a particular exchange itself. I'm just sayin if I stole or eventually possessed stolen coins that I'm trying to launder, I would totally say "they were stolen from Hitler himself....." (yes, I went there... cuz you said you're from germany.. lol)
Just my thoughts.
PS. I have seen 39873975957 posts requesting some coins from you for no apparent reason. I wouldn't mind jumping on the bandwagon... lol
The only reason I can imagine why one might consider sending bits of BTC to random people is that you are a true believer in the concept of virtual currency and want to spread the btc's for a better btc economy... AND if you have a SHITLOAD that you don't mind spreading the wealth.
