If you are US based and all you want to do is trade BTC to USD and USD back to BTC in hopes of making a profit in a controlled regulated way then Coinbase wallet might be the way to go.
If you are talking trivial amounts (and the value will vary person to person) would an easier to use wallet be better?
Even if it's not as secure as we would like, if it's difficult for that person to use, it might actually be more secure for them. Because, a wallet that is more secure / better but more difficult to use (once again for them) might cause frustration / mistakes.
As much as i hate custodial service, you made a good point for people who only care about profit.
But for actual wallet (not custodial service), i think we could find point between user-friendly and secure wallet, where the point depends on users preference.
Safe enough? I could agree.
For newbie? No, it's too complicated for newbies
I believe it would take a few days for newbies to learn, and a few more weeks to be comfortable with it. We learned, didn't we?
It's also better to learn, than to lose your coins.
