But do you really think it's an interface problem, or does the crave for convenience just overdrive the impulse for funds safety.
When the bank ATM was introduced, many people claimed that they would not use it because it was complicated. The same thing was said about online banking. But today, many Nigerians are comfortably using these platforms. One does not need technical knowledge to learn the basics of self-custody. Any literate person would easily understand how to use and safeguard a wallet if they are interested. My take is that convenience is the major reason people choose noncustodian wallets or platforms.
You are right and whenever they are careful with their data they can as well safeguard whatever it may be.
As a matter of facts, the people whom we think can not secure their wallet are the people who do end up securing their seed phrase properly than we can imagined, and even when we talks about ATM card, even now old women and men do use it provided that you told them how to insert the card and input their pin, the easily go to the Machine and have their cashed withdrawn without having any issues. Same its with the non-custodian wallets.
