Since they can't prove that the token printing is not 1:1 of the assets they have (treasury bonds, cash, assets, Bitcoin), what guarantees the price is the confidence that Tether will meet its obligations and that the price will always remain near $1, but if the peg is broken, even if it is due to the loss of stability in liquidity through traditional banks as happened with Circle and this continues for several days, the result will be a collapse. Panic can lead to anything bad in the economy.
Tether has improved its proof of reserves and I now think we can trust their reports. Additionally, Tether has invested in various other areas like BTC mining, BTC reserves, and gold... Tether's total asset value is greater than the total value of USDT on the market, so we can rest assured about USDT peg.
Risks always exist in this market but we should look at it positively to survive and continue investing instead of constantly worrying. Stablecoins have become an indispensable part of the crypto market and they provide extremely good liquidity for crypto assets, we cannot eliminate or refuse to use stablecoins ^^
