Bitcoin doesn't have to beat the banks, they can both co exist. We will always need the loan service that banks provide, bitcoin can't do fractional lending like how fiat money can. You can't just create bitcoins out of thin air, doesn't work like that.
Yeah I agree with you bro, Bitcoin and Bank can coexist both, we are also need the Bank to withdraw
our fiat money from result we get from Bitcoin. I think Bitcoin always need the Bank, but the Bank cannot to controlling the Bitcoin.
I don't think so. Withdrawing and buying Bitcoin is possible without banks. There are money transfer companies and other outletd that provide that service. For example in my country, we can withdraw Bitcoin by converting it to our currency which is Philippine Peso by local exchange here (coins.ph) and we are able to withdraw it through Palawan Express, Villarica, and etc.
