Personally I only trust USDT as it has a proven track record. I don't doubt that some shiny stable coin might pop up, infact I think it's only a matter of time though, but then, I'm part of the people who only trust the old coins and the older projects that's stood the test of time.
Ethereum price chart gas been truly horrible, and after some crab walks for a few weeks, it's dipping again
I'm sure we will have stablecoins to rival or even overtake USDT. Then, it only depends if you trust their issuers or not, because otherwise all major stablecoins have some hidden or known strings their issuers can pull when they need to.
I know, I understand. Perhaps it's just my inner trust issues lol. I feel like going forward, we'll have more scam in crypto rather than more quality project
