tether is simply irrelevant because it is not being uses as much as you think it is. the volume that it has indicates it very well.
this is a new thing that i have been seeing you and a couple of rather newly created accounts are saying! and honestly i can't see how we can even start talking about USDT while there are a lot of other things wrong with these platforms that are much bigger.
I wouldn't exactly call 50 mil irrelevant, although its impact should be less than the Finex hack.
