Sounds right but if there was a general departure from crypto, I don’t expect Phire’s observation that “USDC, TUSD and BUSD, they are indeed drifting slightly high” to hold.
Departing from crypto is generally done in two steps, first convert from speculative to stable then convert from stable to fiat.
If some exchanges are making the second step much harder than the first, then a lot of people attempting to depart crypto could have the effect that we're seeing.
