They already said that their USDT is not backed 1:1 by fiat (wording aside, we know what it implies): https://www.coindesk.com/tether-says-its-usdt-stablecoin-may-not-be-backed-by-fiat-alone.

So I guess this pump machine is still continuing. Their banking issues are also popping up every now and then. In short, never store your money in USDT for too long.
