Be careful with your trade, guys.
This is the USDT Dominance chart in 4 hours timeframe. As you can see that the USDT.D is likely to retest 3.66% level after which it may bounce back. Currently, the USDT dominance is at 3.8% level and if the dominance drop to 3.66% then it'll give some room for the altcoins to grow.
This growth in altcoins won't be for long if USDT.D bounces back from the 3.66% level. If the dominance drops below the 3.66% then altcoins will pump strong. So, keep an eye over it and trade safe.
Note: It is not necessary that the dominance will exactly bounce back from the said level. If it has to bounce then it can bounce anytime.
