But when more people are ready to hold, I guess there will be less possibilities for this coin to get collapsed. Still, there cannot be anything to be done when more people prefer not to hold.
So if tomorrow it's announced that there is only a small fraction of real fiat to back USDT, you're gonna hold yours?
Everyone will panic-sell it. You will see a BTC at say $9000 on Bitstamp or Kraken, and $35000 on Bitfinex/Bittrex. And that will be the first step, after that all crypto will crash again, even more. I'd say, it'd better be now once for all.
And then god knows what happens to USDT-supporting exchanges, they are gonna have massive debts.
