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?
it simple, just because its a decentralized financial system that can not be manipulated like fiat, that's why they dont want to accept it. government of every country want to have total control of all monetary movement both in and out of the country, now bitcoin now prove to be a bridge against their monetary control since it can go and come without their notice or even without their awareness. so the see it as a threat that's why they find it hard to accept it fully the labeled it a
"gate way to fraud and embezzlement of fund". apart from this option i pointed out, i dont see a thangible reason government of many country will not accept bitcoin in full.
