People can Trust USDT but for a short period of time coz it can be controlled like Fiat. The deal should be if you trading and Altcoins are losing covert to USDT when they start to bull you recover your tokens from USDT.
The tactics is called tethering. Before the USDT and other pairs came up crypto trading was either buy low and sell high. There was no way anyone could convert in expectation that a coin was going to crash for a quick gain. But now all that is highly possible. That's what I use the USDT coin for.
So it's very risky when you use it for a long time, you might lose big time.
It's not that you may lose. It's just that you may not make extra profit if you tether a coin and it begins to pump. That's just it. But what about you don't tether and the coin begins to crash? Is that any better? Well, it's not.
