Since tether has emerged as a fraud company that has stole money from the people and there are not enough dollars to support the tethers, I don't use it anymore. Anyone who uses tether right now has two reasons why, firstly, they didn't know tether first was a fraud scam company that they could just check. Or the other one they don't know that it is a company. Many people just want to trade and are happy to use exchanges and their tether options as they realise they don't care about the tether itself. They care about ease of trading and after their trading is over they go back to bitcoin, so all they used tether was for trading purposes.
You are wise enough not to use Tether, but I think you are overreacting about this coin.
If this is indeed a fraudulent coin, there should be no exchange willing to trade it, so the exchange party is also indirectly responsible for this coin. we have to make the best use of it because usdt is very important for altcoin pairs in the current bitcoin condition, at least to maintain the value of assets for a while.
There is no relation between the USDT and scam. USDT is a legit coin which would blindly be trusted until they have some negative news about them rumoring the markets. USDT is really good to trade with because even in stock/forex trading those traders use stable pairs like euro, usd, etc which gives them profits and the same can be treated in the cryptocurrency trading too.
We could gain profits from trading if we have the ability to identify a proper trade and than the second step comes for choosing the market pair. Bitcoin gives profit from trading with some altcoins number of times but for me, USDT has given huge profits for trading with smaller price altcoins.
