First of all you should know that "USDT Dominance" is always moving inverse of BTCUSDT.
Tether's dominance has reached key support, but don't rush to sell your assets! But be careful.
Some altcoins have not yet touched their bullish target, each chart should be checked individually.
Probably, after a few weekly candles in this area, Tether's dominance will return to the top to complete the g wave.
As Tether's dominance returns to the upside, Bitcoin will probably reject towards the 31000-32000 range.
