I cannot see it turning out that way for a coin that doesn't have a single point of failure. I have always said that when it comes to a decentralized coin like BTC, there is a limit to the support people should expect from a centralized government.
Bitcoin might survive, but there are a lot of things that could go wrong when powerful people/entities with deep pockets start to take interest in it. I mean really, it was originally meant to be a way to pay for things (in other words, a form of money), but that's gone right out the window because of high fees and confirmation times. Maybe my imagination is running a bit wild, but when I see politics and big business getting involved with bitcoin the only outcome I envision is corruption or appropriation of it somehow. The US isn't the only government in the world, right?
Politics is about interest, so governments are involved right now because they want to hold BTC reserves and make returns from it in the future, and also get on the good side of crypto people, who are a lot, for future campaigns and elections, and for other few reasons. Worst case is they hold a lot of coins and manipulate the price temporarily, or they withdraw all interest about BTC, and BTC will still be fine.
Oh, I don't think that's the worst case scenario by any means. Think about what would happen if the US government tried to fund Social Security with a bitcoin reserve....and then bitcoin went into one of its extremely volatile phases--or straight-up crashed for an extended period of time. That would be a horror story for a lot of Americans. If I had an hour to think about it I'm sure I could conjure up some other negative outcomes.
But I'm not hoping for any of that; I'm just concerned as a lover of bitcoin and what it currently stands for.
