Sometimes I have the same thoughts as you, the influence of the central bank on countries in the world can immediately stop the development of bitcoin, because many governments are subject to the rules made by central banks, but they do not do so. If we see the USA is a superpower with its dollar currency, but in reality USA has a lot of debt, then the question is "who is more powerful than the superpower"
If this is what you think then you have really lost the whole point in understanding Bitcoin as a decentralized currency. The US has tried many times, so has China a few times, and lately even other countries like Iran have tried to ban Bitcoin. Central banks have no power, sanctions of Bitcoin addresses do not prevent anything,,, banning the trade on exchanges? Now people understand P2P trading and can buy and sell as they wish.
Bitcoin's power is that it has no power, but the power belongs to the network. The people and the users who choose to use it of their own free will.
