Yes it's freedom but not all countries in the world completely approved cryptocurrency trading or owning the crypto. also people have to proper knowledge about crypto otherwise they can lose by investing in crypto.
Yes, that is the power of the government, no matter how free crypto is, the government always has the sense to limit its movement if they don't want it. such as by making some regulations that make crypto owners or activists not that free. They may not be able to limit cryptocurrencies directly because of their decentralized nature, but they make various regulations that limit the movement of people in crypto in their country, by regulating existing local exchanges, regulating their use and restrictions.
but that's what they always want to do and they want to control. so this makes our freedom limited to the scope of the country. it's just that fortunately this is the online world, while we can optimize the chances to be active online, let's optimize the global one first.
