Hi my response might be very delayed and I do apologize about it but here it is anyway. I don't think much will happen in the sense that it couldn't happen because of regulation and the actual enforcing of the regulation. The manipulation of the coin is in the 24 hour circulation and as we know tethers value doesn't change that much because it's based on the dollar. Regulation is far away so it's the wild west in crypto and for a coin like tether in which even the worst news can't alter your value than there isn't much to do. Again much apologies on the late response.
