Bitcoin vs altcoins, will they survive? of course yes altcoin is just depending on the bitcoin it is obviously in the some exchangers, but if the bitcoin goes down altcoins will absolutely down also cause as I said altcoin is depending on bitcoin value.
Bitcoin is the king for all altcoins if the price of the bitcoin goes down then automatically the altcoins price go down. But before we had only one big digital currency it was bitcoin. Now we have many alternative digital currencies. Eth is the very quick growing currency in altcoins. It crossed $250. So in coming days, Eth will become popular like bitcoin.
