I think bitcoin and altcoins are one dependent stock ... if bitcoin rises altcoins will go down ... whereas if altcoin rises bitcoin will go down ... that's one that proves that bitcoin and altcoin are dependent or related ... thank you ....
Most of the time they have opposite waves, yes when bitcoin rises alts are down. But last time when there's a full wave that made the whole crypto currency market on a red market. They are related and every alt coin is helping bitcoin's price because when someone buys an alt, that makes the demand of bitcoin higher.
