You know the drill. When Bitcoin rallies hard, altcoins dump. When Bitcoin dumps, all the rest dumps too. But when Bitcoin is sideways, altcoins rally and some go their own price action.
Everyone in this subsection of Bitcointalk is waiting for altcoin season to come again. Some have already given up.
I will try to post my observations about the market relationship of Ethereum which is the current lead indicator of altcoin market health to Bitcoin's.
altcoin prices are currently mostly influenced by bitcoin prices, so when bitcoin prices are dumped, altcoin will also follow it and when bitcoin pumps, but not all altcoins will experience pump prices even there are some altcoins which tend to actually decrease in price, and this is usually caused by many traders who sell their altcoins with BTC pairs, thus, pushing BTC price up in the market.
And I do not really see any reason why this is not going to continue, the altcoin prices have been influenced by bitcoin for a very long time, when bitcoin goes up many altcoins go up as well and when it goes down altcoins go down as well something really important is going to have to happen for that tendency to change, but I'm honest I do not really know what that could be because everyone seems to be incredibly interested in the price of bitcoin and disregard the rest of the coins in the market.
