Despite the massive growth, advancement and advantages of Bitcoin and most crypto currency, why is it hard for most countries to fully accept it is or permit it's exchange?
Well because some opposed to it. They cant control it since bitcoin is a full decentralized. Ofcourse some from the Govt wanted it taxed but some users hate to be under surveillance too from them and thats what Satoshi goal not to be underwhelmed by the Politicians. He makes bitcoin for everyone and no one should take advantage of it.
