The explanation of the USDT chart is omitted, so it is a supplementary explanation.
While BTC prices continue to decline, new USDT is being issued.
This seems to have the power to buy.
It is making me think that it may be continuing a slow downtrend due to the fight between the whales and the factions.
If there is a buy-in force in this downtrend, it is expected that the downtrend will turn rapidly into an uptrend.
