Some Silk Road users sold perfectly legal items, like art and books. I wonder if any of the legitimate users will be asking the FBI for their coins back?
They could have used more legal sites, such as Bitmit, or the forum Marketplace.
No. No. Legal means legal. If I sell a hot dog on the same corner as a drug dealer, are my profits subject to confiscation?
But if you sold them at an illegal dog fight pit they might be.
No. SR was not an "illegal place". Something illegal has been done there, but the website itself was not illegal. If someone is selling a stolen good on ebay, will everything sold there be illegal too? Of course not. They seized all the bitcoins they've found in the accounts, but I'm pretty sure that those belonging to (the few) people selling legal stuff there, could be (legally) returned back to the legit owner once the case is closed.
Have any of these legit users approached the authority holding the coins in question?
