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?

Haven't you ever read the slogan on the blockchain webpage? "Blockchain is your own Bank" so we don't need that. What we need now is infrastructure to facilitate the use of cryptocurrency in the real world such as payment cards. Maybe this will be better than making a cryptocurrency bank.
