so whats the connection between bitcoin dominance and altcoin price drop everytime price drop bitcoin / altcoin bitcoin dominance goes upper and upper is this a game or due to Market Cap
Bitcoin is most real world used concurrency, that is why is most stable. Stable means that when price goes up it goes up least and when price goes down it goes up least. Now we are in bear market and prices of crypto coins goes down so Bitcoin dominance is increasing. 50% is not that huge. Until early 2017 it was most of time over 80%.
