Meanwhile, Altcoins are making large gains vs. Btc.
I didn't see that. Alts also went down when bitcoin goes down. Everything is in bad shape and the gains were much better with bitcoin before it has corrected.
It was very quick. Top altcoins did register green earlier but ended up with red after hours. There are still a few altcoins with green instead of red. THETA is even producing almost 30% of growth right now.
Altcoins going down when Bitcoin goes down happens but not always.
