I don't know if you agree with me but if you are familiar with a gear shift you truly are. Understand what I mean. Gearshift is a device used to engage and disengage gears in any type of transmission of mechanism. Bitcoin in my opinion does the same in the crypto space. Whatever the performance of BTC in the market also altcoins are affected. It is bitcoin that directs the market status which is good to some who are real and bad to that althat'shatise just there for nothing except for fraud motivation.
You are right, bitcoin does have a good influence on every altcoin in the market, and this can be evidently seen in its market dominance.
The current market dominance of bitcoin which is about 42%, is how its able to influence the rest of the market, we hope that as crypto develop more and gain much more adoption, bitcoin's dominance will come down spreading it across several other thousands of altcoins so that every altcoin out there could derive their own worth and not depend on bitcoin moves to go up or come down in price.
