If there's any HW manufacturers that will open custodial service (bank or something else), IMO Ledger is more likely to do that since they already offer Ledger Recover service.
Didn't Ledger Recover Service negatively affected their reputation or people immediately forgot and forgave?
AFAIK their reputation is partly ruined among cryptocurrency enthusiast or people who have serious concern about security. But among general people, their reputation is still mostly good. I definitely in the former, because in past they claim it's impossible/there's no way to extract the private key/recovery words, but turns out it's possible.
To my mind, doesn't matter how serious you are about the security, the company lied to you and it was not a simple lie, it was the biggest and most brutal lie. They promised you that it was impossible to extract keys from secure chip and then they come up with recovery service. This fact alone questions me absolutely every part of the wallet and the company.
It's a little bit sad that companies can treat their customers so badly and people will swallow it. Well, it is what it is, some get what they deserve.
I don't know where you live (and it doesn't matter), but 10% on fixed savings in the bank sounds like a banking joke to me. I would have nothing against depositing EUR 100k in the bank and earning 10% for one year, with the deposit being insured by the state.
If we keep in mind the inflation, it's always better to start a business instead of saving money in the bank when its all of your money. If you have other 100k besides this, then no problem.
