I'll try again ..

First, I don't pretend to understand the 'technical' aspects of crypto at all ..

I do know that all the wallet security features are exclusively
focused on foiling access to one's wallet ..

Judging by the number of threads on this board that deal with "theft of coins" ..
foiling access is clearly not enough ..
People are fallible, they're going to use weak passwords and employ sloppy procedures ..
I think you'd have to assume that wallets will be hacked/compromised at some point ..
Therefore, there must be some additional security feature/procedure etc etc
in order to authorize a withdrawal ..


That's all ..

The average user has got to feel that the wallet ( hot or cold ) is secure and utilitarian ..
It's got to be as intuitive as online banking and online trading ..

Just sayin ..

Triff ..
