I've been monitoring the market for a couple of months now. Most of the coin value rely on the price of Bitcoin. If the BTC price goes up, every altcoins will follow and if it will goes down, the price of every altcoins will goes down as well. But the question is, Bitcoin price/value is still going up but the price/value of every altcoins especially Ethereum goes down. How did this happen? Any logical or scientific basis to explain this. As of now, I am still confuse. 
I think most cryptocurrency are facing a lot of competition in the blockchain technology space,especially Ethereum is the most affected cryptocurrency with the emergence of blockchains like NEO,CARDANO and EOS, however with the limited supply of bitcoin has been withstanding the pressure all alone
