The moment you see any government trying to officially adopt bitcoin you can be sure that they are going to try to manipulate it to their advantage, we know that politicians all around the world are corrupt and it doesn't matter what tool you give to them they are going to try to find a way to get their way with that tool, just look what happened to gold, one of the best forms of money that we have available was corrupted to the point that governments could create mistrust in it and they could introduce their fiat currencies with impunity.
Indeed. Even with paper cash, some government officials are using their powers and trying to get money from the people. What more if they'll be given a chance to manipulate cryptocurrency. They might take more. Even if other says that they only want the good for the people who wants crypto and Bitcoin to be legalized, behind that smile for sure they're hiding something on their sleeves. Corrupt can't be removed from the government. They'll just take advantage of our money even with cryptocurrency
In order to cope with these challenges I feel that crypto currencies shall always remain decentralized rather than being governed by any government body. There is no doubt that corrupt people are everywhere no matter how strict the policies or rules are, those in power always find ways to exploit poor. Bitcoin shall be legalized but people shall never accept centralized digital currency.
