I need to know which stablecoin you mean, if you refer to UST, then the collapse of UST occurred due to depegging, in contrast to USDT, USDC and BUSD, these three coins seem to be under scrutiny by the SEC, especially USDT (tether) because the stable supply of USDT coins is on the way. SEC monitoring, but still someday stable coins can fall if there is no backup paper currency to keep the price really stable.
