We've discussed this. It was a bit lower risk to validate the hardware works with a new token than the additional complexity of Dai. A lot of other challenges there too but we're a small team.
Sounds fair. I really like the technology though and think you guys have the most unique take on paper crypto so if the actual token itself becomes a barrier to adoption due to volatility/stability (which is a leading reason why stablecoins are all the rage right now - as I'm sure you guys are aware), you guys can license out the tech or produce bills for Tether, Dai, USDC, and other high traction stablecoins. Our small stablecoin team (releasing product Q1) would be interested ourselves if we were to ever get into the 9 figure market cap range.
