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 but crypto currency like bitcoin that would have change lives and alienates poverty from the world, government are afraid of its cumulative value.
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?
Well, at the initial beginning, peeps probably did not believe that bitcoin would be what it is today and where it is today, for many, it is still a mystery, I personally believe that even satoshi himself or herself, or their group never expect the kind of success bitcoin have achieved, it all started with a line of code on probably an old computer, and in 2009, something was burn that would completely change the way the world see and value money, bitcoin has become a force that can't be reckoned with, the government probably have deviced several means they can get hold of bitcoin, but have discovered it's impossible to ever be controlled by a single entity..
I don't think that it all started with a line of code in an old computer, no one can create something this significant and strong by just sitting on a computer and writing a few lines of code, to me, it seems that it was a vision that was thought about for a very long time and there was a lot of planning and brainstorming and creating ideas to create something that can be used as an alternative to traditional financial systems.
