Insider Trading - very usual for situations like this one.
Can't completely ban trading ? - They sure can. It will just take a lot more time then China, because they actually have to vote it.
Not governments problem ? - YES ! People have the freedom to do whatever they want to with their money. Also as far as we know, crypto's don't pose a systematic risk for the economy at this point.
Right bro people have that right but if government make interfere there what they can do.
