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 don't know about any corrupt bank here in our place since most of the banks here are actually government run and they just can't shut down.
I can agree that your money is safe in bitcoin wallet but the value of your coin isn't safe as it is highly volatile, just like now, the value of bitcoin dropped dramatically in over 72 hours.
