Trusting those stable coins after Luna crash is not at all good decision and the owner of funds has cashed out millions already and his Twitter profile going private giving clear signs of rug making the market loose badly and also some mentally sick due to big loss.
Some stable coins are better, Terra UST was just so common because it got to billions of dollars marketcap, I think it got to $10 billion or so. There are many algorithmic stable coin in the past that failed just like luna, there are good ones that are not algorithmic, they are better, example are dai, usdc and tusd. But I will recommend people to convert to fiat which is safer than stable coin.
If we can't manage to hold, converting our crypto t fiat money is highly recommended rather than sacrificing and hurting ourselves thinking about the current situation.
But if we can, I don't think stablecoins are an option due to some issues of scam exit and devaluated, we instead choose Bitcoin and ETH for long-term investment. With this bear season, we look for sustainable projects, not those that have been created for hypes and useless projects. Likely not meme coins.
