It dosent have any effect because it’s just a dominance that is derived form the share distribution of the total market capitalization.
Dominance means domination . so if that drops , the price is also expected to drop but 40% is only small so i think its not a big issue at all and besides , that drop can still be recovered because there are always new people that will enter on the bitcoin industry .
Correct because the last bull run, BTC did not increase more than x10 but altcoins did increase more than x10 , some even have a x100 increase.
Therefore, when correction happens, it's just normal that altcoins will dump harder than BTC and we can confirmed that now.
How can that be possible when we all know that alts and btc are moving as one ? When it comes to pumps , alts cannot pump 100x or more compare to bitcoin because alts do only have a small base value . maybe you hold alot alts , thats why it make an illusion that they increase alot .
