It's true that USDT is not an algorithmic stablecoin, so it's different. Market sentiment, though, tends to change quite quickly: I would not expect a collapse, if and when it happens, to take weeks. It's not that different. There's also little reason to have confidence in Tether's reserves: Tether have refused to have traditional accounts produced, and they are known to have lied about the nature of the reserves, having initially claimed to be 100% backed by cash, but due to a leak we know the reserves include debts. Debts generally are illiquid, and you need highly liquid assets to defend a peg.
