There are two types of BTC

Freshly minted coins and tainted coins

Newly minted coins sell at a premium to the quoted price

Miners generally keep new coins

All stolen property remains the property ( unless compensated ) of the owner no matter how many times its sold

BTC can be tracked and if someone tracks a stolen coin to your wallet its gone like a puff of smoke back the owner

Its estimate 4% of coins are lost to scams each year so a lot of stolen property that will one day make it back to the owner
