Now that the talk is over, I wanted to focus on user perception of usage (after coming from centralized exchanges)...
The other part was using Subway sandwiches and Fiat as an "atomic swap" comparison. As you can see, I might have been talking about similar things as atomic swaps or trustless BTC gateways... but I needed to say it in a way that gets regular users voices heard as we move forward. I think now it makes more sense (after hearing the way I made the presentation) as to why I wanted to do what I did. :)
Thanks for your comments during the show. They were helpful.
