•Bitcoin replacing Banks.
I don't think that it will happen in the future, there is no way for cryptocurrency to replace banks, government is against cryptocurrency, they wouldn't accept any decentralized system, but if though cryptocurrency will never replace fiat, I still don't care because I can still explore crypto world even though it is not yet accepted in our country and besides there is no way for them to ban cryptocurrency.
Banks become a buffer for the economy in a country, if banks are eliminated, and cryptocurrencies are replaced which cannot be controlled by anyone, then I think the government will object to that. and even if it happens, I think it will still take a long time, maybe generations after us. For now, I think it's better if we enjoy making money from cryptocurrencies
