Cars aren't a currency, but if the police catch you in a stolen car they can do something about it.
What makes you think the police only police currency?
Yep. They can launch an investigation, only if he didnt repay you or what not....
Not as simple as that.
1DiCe1 has to prove ownership of the BTC's she deposited. Which might seem a difficult task in legal terms, I heard.
Only then, a full report could be done by the Spanish police, for them to legally obtain the IP holder's identity from ISP and then fill in a court case.
This will never happen regarding to 1DiCe1 I'm afraid, and investors have nothing to pursue with the authorities since they lost it fair and square.
Which brings it all back to zero.
They may have lost fair and square against 1Dice1 but they still bitcoins left after he won!
You're right.
