All crypto currencies market value are bothe depending on each other. When bitcoin goes down, other coins all do the same for this crypto currencies value depends on the value of bitcoin. In simple explaination here, bitcoin is the mother of all coins, and they will just follow bitcoin rate trends.
Can you tell me the proof if the price of every altcoin depended on each other? The fact that the market has been controlling by so many speculators and whales with a lot of money. I can see that if those are making an unfortunate trend and then a lot of altcoins will be turning into the bearish trend. I've seen it in so many times about the patterns give a significant impact in every coin, and that was not depending one to each other
