Safest Stablecoin?

So I’m determined not to make the same mistake I made in the last bull market and not take profits. I held all my coins like they were my children and never let any of them go. Not this time! I’m abandoning those bastards left and right. My plan is to DCA out of most of my positions as the market ramps up and (hopefully) peaks mania wise. I want to hold stables until the market crashes again (I’m looking really long term here) and then DCA back into mostly BTC and ETH. So my question is which stable coin should I be stacking for longer term holding. With my luck I would have used UST this last bull. Thanks for any advice.
