Before the existence of bitcoin they're many other digital economic assets that is in line with government policies like crude oil, gold and much more, government where comfortable with this assets trading online, including forex
You know this is so...because all the mentioned gold, currencies etc are all regulated assets and these are guided by stock exchange rules to be traded.
but crypto currency like bitcoin that would have change lives and alienates poverty from the world, government are afraid of its cumulative value.
This is not a valid argument, people have lived a good life through scamming & fraud and the perfect example is Hushpuppi and are we going to say just because it elevates one from poverty or any kind of impoverishment then govts should be all thumbs up with this..I don't think so!
Of course I bet this isn't what you meant but its relatable and governments at this point what everything regulated to support them.
Bitcoin is an assets that we shouldn't lose or allow to dies off, if you check history of all money weather digital or paper bitcoin circulate faster in values and distributions. As highly respected as dollars not all countries have it but bitcoin is 14 years now, the world is aware of it. Do you think bitcoin will stay if government totally remove their hands or stand against it?
As long as Bitcoin sits on a technology called the internet that we heavy rely on today, be it transportation, health, finance etc I don't think our governments have to power to stop btc and cryptos in general!
