As we all know it when bitcoin price goes down, most of the coins are heading down too. That's because bitcoin it is the Heart of all coins if its sound then all of the coins are good, if it's Bad then all of the coins are going down too. most of the time other coins are following the bitcoin price. just look up the market right now.
It wasnt the bitcoin,but the blockchain i guess is the issue here.and its the heart of everything
But you are right about when the bitcoin value drops same happen to most of the altcoins here in this market
And i believe it is because bitcoin is the highest capitalized crypto and the majority of traders in this crypto market
