Crypto's motto has long been: be your own bank. But most people seem to have forgotten them already. Through crypto we could do without banks, but apparently the people do not want that. Many people are already waiting for a bank to take care of their coins. Therefore I believe already that there will be sometime also crypto banks. I don't think that's good, but apparently people don't want change and prefer to use banks for their money and crypto. 
that's the motto of decentralization itself, but many of us begin to think that centralization is important. when your coins are stolen by someone of course in decentralization you will be responsible and accept all the risks yourselves, and many people today think about who can take care of their money in crypto, and bank crypto might appear in the future because of this.
