Your missing the point,people believe USDT is $1 because for years tether claimed it was backed 1-1.then recently they were forced to admit it wasnt.
We were all lied to by tether.
The people getting screwed are the exchanges giving bitcoins and other cryptos for Tether who treat it's value as 1:1 to the dollar.
Doesn't really matter. When I started using BTC it was much below 10 USD and I'll keep using p2p money (currently bch) even if all the speculators flee.
'Cause the people holding tether are the ones who are going to have their pockets turn up empty. The cryptocurrencies themselves will fall shortly after in response to the real market
