Dai Payments at ETHDenver
ETHDenver's radical experiment to use Dai to buy food had mixed results.
Good news, 60% of transactions went through.
Bad news, 40% didn't.
I seem to recall Austin Griffith Burner wallet not being entirely bad if at all. It actually functioned quite well during last years, Ethereal Summit in Brooklyn. They only bad experience that I recall was just the long lines and the wait for the food to be ready. Sounds like this year it is much different.
