I believe easy of use should be accompanied by security. In order to drive adoption, crypto wallets should be designed in such a way that they can be appealing to first time users.
I think they should also know that hot wallet are not ideal to store a lot of money, as mentioned above. Would be nice if all hot wallets regardless on iPhone or Android give a notification that their app is not suitable for long-term storage in most cases. Since newbies probably won't start learning and just use the app + skipping some guides.
