Is tether risky from that purpose? Even if SEC warrant something like XRP, what will happen to Tether?
What about another alternative stablecoin?
Yes definitely risky. This is gonna be a big fud later on, it's a long time file against tether and they just now gonna be put in check. I'm not sure what will happened on tether but definitely some will disable trading pair of this. Like what happened on xrp. However that's still not sure.
But Binance give a hint few days ago. When they open a perpetual contract trading via busd.
