The toughest hardware wallet
Discussion
I think, I still have this brick somewhere at my parent's place. 😺 
We should have a challenge. What’s the oldest device that you can run Nostr on?
Would be interesting, I have Samsung I9300 Galaxy (2012) , the oldest android I have on hands, but it needs new battery.
Also this Nokia 5 https://www.gsmarena.com/nokia_5-8571.php
It would be a fun little hackathon
