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.
Correct use bitcoin wallet is easy because we do not necessarily have to create an account, and as it should if we use the bank. But I think we can not be separated from the bank, there are indeed some banks get the money its customers. Therefore we must choose a good bank, or the bank associated with the government. But because I am still using fiat then I could not leave the bank
