Justice. It seems that the authorities are not really going after criminals in the crypto world that much. I wonder if it is because they have no idea what all this stuff is?
In the US, a criminal court is decided by the jury. The jury is usually 9 ordinary folks from the general population. Try and explain crypto-currency to regular people like your neighbor, the mailman, the pizza delivery guy, etc. Very few people will understand it. Hell, I've been involved with bitcoins for almost 3 years and I still don't get it 100%. In the US, to be found guilty of a crime, the entire jury (all 9 people) must agree that the suspect is guilty. If one person decides the suspect is not guilty, then the court will find the suspect not guilty.
I don't know how the criminal justice system is in other countries. I'm fairly certain that in most Asian countries, it's not as difficult to find someone guilty of a crime.
