Ok but we dont care about blockchain. Are the bank fees going to be lower? Probably but not by a lot.
Bitcoin is superior to the banking transaction system in anyway. But at least they get familiar with the tech.
They get familiar with the tech and they get to really see how money moves, making it harder for people to evade taxes and for every transaction to be tracked. This is why the blockchain shouldn't be used with regular banking imo. No-one should be allowed to look and see where your money goes at any point, unless it is a court order.
There is already 0 privacy with bank transactions, they already know where the money is going.
But with bitcoin there can be privacy once a few more features come in.
