The Bitcoin dominance has been dropping and dropping, the only question is "Where is the Bottom?"
Base on the chart, Bitcoin dominance has came back to its origin. This is why most Altcoins are pumping due to the fact that the dominance has been dropping.
Is this the indicator that a big dump is coming?
If Bitcoin dominance continues lower and lower, Altcoin season will continue to go and go, but when Bitcoin dominance bounces from here, Most alts will take a very nasty dump of at least 10-20%.
