What do you mean by "value trust transference"? How to make more people who don't use cryptos now, to make using Rockstable in the future?
I think stablecoins should be as trusted by ordinary people as fiat is. That's not so easy, but at first Rockstable has to make ROKS be easily reedemed to fiat.
It's hard work, it will take much time and only one project (like ROKS) can't deal with it. It should become normal to pay with stablecoins in different corners of the Earth.
