Tax evasion is a problem everywhere, I guess eventually some people might use bitcoin for that purpose, I don't think bitcoin is particularly good for criminal activity, the digital trail may be very difficult to eliminate nd law enforcement agencies will get up to date with latest technology, eventually.
What the hell are they going to do after you run your coins throught a mixer? or even depositing your coins on an exchange with a fake email using a VPN then withdrawing. The trail is cut after that. I dont think they are going to go after that many problems, unless you are like moving billions or something.
Correct, you also do not use an off shore for a couple thousand.
The problem is not hiding bitcoin when you have bitcoin, that part is easy, the problem is getting from Euros or dollars, let's say a couple million, to bitcoin without leaving a trace, or spending a lot of bitcoin just like any other form of money without having any away to show where it came from.
