The banking sector is failing us, more than we know it. You go to any bank on a Monday, you will see a long queue of people with complaints at the customer care section.
More of this type of incident will occur frequently in the future unless banks improve their security. The day I thought of this incident that is happening in the bank, I came up with a suggestion: banks should set up a facial recognition, SMS, and email verification system that customers must pass before spending a certain amount. a security measure to further verify the identity of the account holder before spending large amounts. Let's not be surprised that one day the press will release a report telling us that most of these bank fraudulent activities are being pioneered by some bank staff; that's just the risk of trusting our money with third parties. And the worst part of this is that after losing money in your bank account, if you visit the bank, they tell you to start some legal proceedings that will even require you to pay some money, while your money has just been stolen under their custody.
if you give out your sensitive information to scammers, the banks cannot help much, but if it is due to bank-related system errors, you will always get your money back;
From what Igebotz said here, he's correct, but you can imagine how long it will take to get that money back with the long delays in the banking system these days. What if it's not that individual's money? What if the money was for a contract job? The thing is, all this is no longer funny; let the bank look for a proper solution.
They can as well enable a security that allows people to freeze their money so that only the individual will be able to unfreeze it through some security means when ever they wish to spend some cash.

Mahn, it's not only Nigerian banks; NAB also have some reports concerning fraudulent issues. Banks will not fail in 20 years like you said because you will still need them to spend your local currency, and digital money is not yet accepted by the mass..
There is also no 100% security in holding your money in Bitcoin because you could also get hacked or lose your password or mistakenly release your phrase to a wrong hand.
