This is an interesting development of the Bitcoin dominance considering that the markets were all crashing. In the past most crashing events led to a sharp rise of the Bitcoin dominance while Altcoins were dropping much harder in comparison to Bitcoin. Seeing this could actually mean that we will see a break-out to the downside of the 40% range soon that could lead us to 30-35% levels once momentum is picking up. Generally, one should still be careful trading this setup as markets are reacting strongly to Evergrande's potential defaulting & the sharp rise in cases of the omnicron variant.
Good luck with your trades! Do not consider this as financial advice.
