I think it's one of the main hurdles to mass adoption of crypto. At least with fiat banks, if you are stupid the bank might notice some strange activity and freeze your accounts, or you can claim back anything spent maliciously on your credit cards. You don't get that with crypto. The buck stops with the user, and most users are bad at security.
Aye, but it goes a bit deeper quite often - emails being diverted during major purchases like paying builders, phone call spoofing. Even if you're not a granny it's conceivable you'd fall for some of them.
Soon enough banks will find it 100% impossible to contact any customer as they'll refuse to believe it's actually them.
