I am one of them that support cryptocurrency banks.
Why I supposed is because not all cryptocurrency uses can store there cryptocurrency safely and need support.
Most people dont know about cryptocurrency wallets or have never used cryptocurrency but want to know more.
That's why the web-based wallets like Coinbase are good enough for beginners. Difficult to make it more user-friendly than that. If they can't handle their username/password correctly they shouldn't go to the www.
Once someone gets experience with BTC, he could become interested to use another type of wallet (one that he will really have full control over with his private keys).
Most important factor here is if you have a lot of cryptocurrency and store on a ledge or pc what would happen if something goes wrong. Like the Canadian cryptocurrency exchange where the owner dead and investors lost there crypto because he was the only one with access to the legal.
If this was stored in a bank and was in control of cryptocurrency bank manager then this would have been avoided.
You don't make sense, If I have "a lot of cryptocurrencies stored on a Ledger device or PC" why should I care of what happened to this Canadian exchange. My coins aren't stored there. So, what?
Something sure is that we don't need crypto banks if they're controlled by the same cartel
