For me, I'm happy for my money to be stored in a bank. The bank keeps multiple back-ups of their books and is heavily regulated by our national government. If someone attempts to steal from me or commits fraud there's some recourse by notifying the bank and potentially having those criminal/fraudulent transactions reversed. No electronic inertia (i.e via crypto blockchain) for my bank to approach another and reverse a transaction.

There are also several security features to extracting money from my account: there's an account number, name, physical access to debit card, ccv, account password, OTP, pin numbers. All of which are missing in the typical crypto ccy net.

Furthermore, banks are forced to record identity information from their customers making it difficult for a nefarious actor to conceal their identity.

One advantage for crypo ccy is potentially making anonymous transactions. I don't really have anything to hide in that regard. The mundane shop at the supermarket, ebay or even buying drinks at the pub.. nothing very revealing.

If your life savings are at risk from losing a secret key or simply by someone nicking your secret key then I'd call this a "bug".
