For me I want to use a bitcoin wallet because i think it is easy to use than the bank account . And some bank official is corrupt so our money is not 100% safe. But if you use btcoin wallet you're money is sure safe and you can you use the money I you're wallet in the future.
i think you are some how right about the bitcoin wallets but do you think so???
Banks are opened by investing a lot of money so even if they are corrupt you get the your fiat back but what if wallet get closed?
