Is there any relationship between the two?
Whh must the fall of bitcoin after other altcoins?
there is a relationship between bitcoin and altcoin, because the benchmark of altcoin costs using bitcoin, so it's only natural that bittoin down altcoin also decreases drastically and this will happen anytime but if the increase in bitcoin or altcoin will continue to rise.
bitcoin and altcoin for me also they are sounds to be the partner to be that no matter what may happen on bitcoin there is a possibility that it can ever be on altcoin too.
