I understand that there are US restraints with Venezuela so that we are not fueling their corrupted gov. and dictatorship but at what lengths should the effect Cryptocurrency. I agree w the US that they should not aid and help this economy impoverish the Ven. citizens further but how and where do you draw a line with crypto? I know the US likes to control everything they can but should they be allowed to control other nations crypto decisions/coins?

Thoughts?
