This is exactly the reason why it is not advisable to put a hudge amount of money in the bank, because when you will need that money you will have to through some unnecessary process before you can be able to withdraw your own money which is not making sense to me, because I don see the reason why when you want to deposit hudge amount of in the bank it won't require some unnecessary process, but when you will want to withdraw the money unnecessary process will start. If not for that  bitcoin is very volatile in nature I should I advise each and everyone of us to keep our money in bitcoin not only as investment but also for easy access when you will need your money, at least when you will need your money you can withdraw it anytime without going through unnecessary processes like the ones in the bank.
