Hello mate!
Your government do not care so much about you, they do not wish that you become so much rich that you don't depend on them anymore. Wake up from your slumber, they will tell you that they want to protect you from Bitcoin volatility, that's fallacy
They simply want you to keep using the fiat such that they will be able to tax you to the last dime. They want you to be at their mercy such that whenever inflation comes they print more fiat for themselves and you will be the one to suffer the repercussions. Government of some countries just started welcoming bitcoin since they understood that day bitcoin network is so transparent that they can trace or transaction and the people could hardly avoid tax. This is why they are now clamping so hard on decentralized exchanges and the mixers because these are the routes we could use to avoid them. Be wise!
Lol, so accurate, and it's not only about taxes but they want to have control over people's finances and financial transactions because with traditional financial systems, they can easily do that since they know everything as you use their banks, payment apps, and everything requires KYC from you, so they know it's you and how much money you have, how you spend it, and how much you receive, etc.
With Bitcoin and cryptocurrencies, this thing isn't possible because people can easily bypass this my using non-custodial wallets to store their assets and as long as they are not using KYCed services, the government wouldn't be able to identify whose wallet it is because it wouldn't have any traces or identification.
So, they don't want to lose control is the basic reason why they are always against Bitcoin and cryptocurrencies.
