Diversify. Keep some in a bank with some in USD and some in one or more other currencies. 5-10% in physical gold or silver and bury it in your yard somewhere. I'd probably not trust any stablecoin with more then 40-50k, as there is a rather large risk there. MICA basically ended USDT in Europe, who's to say it won't end in the US sooner or later? Who's the say some regulations won't f**k USDC? What happens if it turns out Tether or Circle don't actually have the money they claim to have and it "de-pegs" and you're left with 8 cents on the dollar overnight?
