What is your reason why bitcoin should stay in the next 100 years! when the government are worried about it?
Maybe our opinions about bitcoin can give hedge to the government.
Why not? I don't know if you have heard how many people had already become millionaires due to BTC and how many lower class people had got an opportunity to grow instead of all bad economic situations and fuds. BTC has made people's life independent of local and fiat currency and they can do any transaction independently of middlemen like authorities and organizations. You should read about the origin of BTC which tells us why it was created. Back in 2008 due to the financial crisis of banks, the recession becomes out of control and all the money in fiat was useless and people are left with zero value in their hands and then Satoshi Nakamoto comes with this new idea of BTC.
Which was newer and people were not familiar with tech, especially with digital currency's value at that time. Like there was a dude on YT who was saying " plz buy BTC for god sake, just buy it, just for only 1$ dollars" Now he is a millionaire.
BTC gave the ones with no money and property from their parents, an opportunity to become independent of them and independent of financial crisis. You can read a lot of threads related to how BTC made one's life independent of the financial crisis and provide them with financial freedom.
You can find more, the thing is, why not back BTC up and to wish of its stays for 100 years because it will provide a hedge against inflation, and what i think, government is worried because BTC is based on POW and totally decentralized which fears them out and they know if BTC did not comply with AML then we have to make something for it so that it could comes under our laws and regulations and we could control it and it's users but that's not going to happen until it based on POW.
