Considering that most people nowadays often find it hard to store and protect their cryptocurrencies, it's best to delegate the responsibility to a middleman. A bank of crypto would fit the bill nicely, as people would be able to secure their cryptocurrencies without ever having to follow the necessary precautions to prevent hacks or theft. As long as the bank of crypto is highly regulated by the government, then it'll be here to stay for a long time. Still though, not everyone will agree to this as it greatly defeats the whole purpose of crypto and Blockchain technology. The idea of a bank providing crypto services would only prove to be viable for newcomers into cryptocurrency. People who're experienced in crypto, wouldn't need this in the first place.
Nonetheless, do you think that a Bank of Crypto will happen anytime soon? If so, why?

I think there are only few people who will only store their cryptocurrency in banks because most people will rather store all of their crypto in their own crypto wallet. Storing in banks is not 100% safe, that is why keeping all of your crypto is still the safest way especially if you are using a hardware wallet, after all cryptocurrency is not like fiat that it is good to store it at the bank.
