Is there any relationship between the two?
Whh must the fall of bitcoin after other altcoins?
I think the prices of bitcoin and other altcoins have generally similar movements. But in the last few months, I can not see similarity between the price of bitcoin and an another altcoin, for example ethereum. In my opinion, the next movements can maybe show us some differences.
It is precisely if I observe that the relationship between altcoin and bitcoin is very closely related so that they influence each other.
in a state of bitcoin dropped where many altcoins were affected and fell. although there are also altcoins that survive but are relatively very few.
