Since suspicious movements have been captured, I think more careful trading is necessary.
The sudden change in USDT dominance and USDT market cap ($)
1. Used to buy coins.
2. Getting out of the coin market (possibly cashed)
I think I can't define motion otherwise.
Also, it can be predicted that the sudden change in BTC dominance was caused by the sudden change in the market cap of USDT, but it cannot be said to be certain.
