Today's discussion about wallet security made me think:
The idea about "not your keys, not your btc (or anything else)" is extremely difficult to explain to no-coiners or to even any non-technical people.

How to solve this to bring bitcoin to billions? Some upcoming solutions are Orwellian-some token wants you to scan your retina. Yikes!
What could be better without writing down words or an extremely long string of letters and numbers?
Some people/projects are claiming that they would provide decentralized identity. I am VERY skeptical of this for the moment.

It seems that at some point there will be an adequate phone wallet with both advanced (to get your private keys) and basic functionality (for noobs).
I looked into wallets and some are gaining more and more functions lately and seem on the way to a more polished product.
Maybe a good phone wallet is going to be a solution.

Additionally, financial institutions will also probably eventually do 80-90% of custody.
They already approved Anchorage for institutional deposits, maybe something else (could be Fidelity) is coming for retail later.
