For all the ETN holders out there who might not be interested in keeping their coins in paper wallets and want to keep their holdings as safe as possiple. I think it would be a great idea to introduce a ”savings” part to the Electroneum wallet.
The idea would be that you still would have the coins that you think you will use or send around in the current wallet. But the coins that you want to hold for x amount of time are in the ”savings” wallet. And the savings could be behind a Google Authenticator code, or txt confirmation, or email confirmation. And for extra security they would move only one day after the confirmation and it could be canceled at any time during that if the user finds out that someone else is trying to move the coins.
This might be interesting also for the users in the developing countries if they decide to have their savings in ETN and not only use it for minutes and data.
And in technical sence it would not have to be another actual ETN wallet. It could be just part of the users balance that is ”ring fenced” (like ETN does when using instant payments) untill it is freed to use after the user confirmation.
