Yes the comparasion between PayPal and Utrust is really clever, Utrust will become better than PayPal with all the features they will release, and especially crypto users really enjoy a platform like Utrust, its a real need at the moment.
I don't think to be better than paypal enough in the long term they should be in use more than paypal. If they can reach this goal, I can't think of what can happen to their value.
Well, first they should get their platform working, advertise it more and get more and more partners with time. Of course they need to get better then paypal with time, because otherwise why should normal payer switch over to utrust if they need to learn about crypto then, but don't have an benefit from this. But everything at once is not good. Step by step, this game will go on.
Because Utrust is the platform for us, crypto enthusiasts! But I agree with you, potentially it's better then PayPal if ethereum scale enough
