There are a lot of good coins that Utrust hopefully will add in the future. But I expect them to only allow BTC and ETH in the beginning. Oh and the UTRUST token off course.
Not sure about this. I could imagen that they already will implement some more, maybe up to 4 or 5 different optional coins for the payments. There was no official statement regarding this, right? But in the whitepaper they at least talked about more coins, as I remember.
Yes, that's what I understood that there will be first around 4-5 different coins. Now and then they will add another coin which according to dev will be dependent on volume, transaction fee, community demand, etc.
