The current alt boom is coming to an end and bitcoin will rule supreme once again!
Bitcoin has always been the dominant cryptocurrency since the beginning. No wonder why all the altcoins right now are mostly based on the value of Bitcoin. If Bitcoin is going down, more often than not the altcoins are also going down along with it. But since the altcoins, or most of them, are actually offering a different set of features and offers, they could gain growth and success apart from the performance of Bitcoin. Altcoins, in this sense, do not just end.
While there have been moments in which altcoins grew significantly on their own most of the time they follow the movements of bitcoin, if bitcoin grows altcoins grow as well if bitcoin loses value then altcoins lose value as well, to me this is a very clear sign that regardless of the market dominance of bitcoin altcoins are incredibly dependent on it.
