I heard about something that happened some time ago where a man won a huge some of money in gambling and he decided to save the money in a particular bank the money was there and later on the bank was closed down and he had to go through a lot of procedures to get his own money he was paid half of the money with promise of completing the payment soon, this won't happen if you saved with Bitcoin.
It sounds like that bank seems a bit shady. I'm not too sure about their process for handling a bank closure because in our country, when a bank shuts down, an insurance agency steps in to cover the deposits. This insurance only pays up to a specific maximum, around $8,500, so if a depositor has more than that, only the max will be refunded. I'm really curious about why he was only paid half and that the balance will be completed soon; that process doesn't seem to follow the standard.
Anyway, if we put our money into buying bitcoin, we're likely to be profitable since bitcoin is one of the most profitable assets when you look at its history year by year.
