You have a legal system available, and banks that have to rigorously comply with that system.

This is true about cryptocurrency as well.

Where will Federal Marshals deliver the summons to the owner of wallet address 0x8723aa67f823dbe785dc923 ?

What percent of BTC has been stolen? What percent of USD has been stolen?

Interesting thought. Bitcoin circulates, and you have to wonder how much of it has passed through a fraudulent transaction -- at any time in the past. Someday when it becomes straightforward to walk the entire life of bitcoin backwards, there may be people who want their bitcoin back...because it's stolen property.

If A has a TV, B steals the TV and sells it to C, who sells it to D...then the TV is still returned to A, and D is out of luck.

But bitcoin can be mixed, how do you decide which of the next transactions contain your part of stolen bitcoins?
