Okay, HODLER_TECH, how do you plan on sandboxing the email client, and how will the emails work in a way that prevents you from tampering with them? I don't think it would be feasible to make each device a mail server, so the address would have to be on a central mailserver controlled by you (unless you have some way around it). The emails would not be encryped, so you could easily MITM the address. Also, what prevents code execution from an email?
Another day of still zero response. sighs

Legendary troll)) Do not worry about him, he sells himself for a pack of smoking pipes, see his activity.
DarkStar_ does not have to go beyond the reach of his WIFI network with his wallet or he can pay by cash. Not everyone has to use cryptocurrencies in everyday shopping. He can also drive a car shopping with his laptop, Trezor wallet, 4g modem and wiring )
Strong accusations from a Newbie with only 2 posts. I would use a Ledger Nano + Cell Phone with 4G though. What exactly about my activity makes me a troll?
