Out of all the options above, I would choose USDC as USDT has some serious issues in their reserve audit reports.
DAI can be used as a back up option too and we can also diversify between USDC and DAI to minimize the risk.
Can you explain more clearly and better if there is specific evidence? Because as far as I know, Fuds about USDT have been circulating for years and many news said that their reserve report is not transparent, clear...But to date, they are the largest and most used stablecoin on the market. Even the news that they will leave the European market because of their refusal to comply with the Mica law has not diminished people's confidence in them.
I don't compare which stable coin is better because for me they are almost the same and which coin to use depends on each person's preference. But I don't think USDT is having problems like those rumors.

The thing is that Tether has never been transparent in their audit reports.
Althgouh they claim that every USDT is backed by their reserves in 1:1 ration but they never went through any professional auditing firm.
So the chances that they are hiding something increases. If they were really backing all of their supply with 1:1 reserves then they should have had an accurate audit report as well right ?
