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. 
It is an evidence for us, that Ethereum price is actually not depends on bitcoins price. Because if it was fully on bitcoins price it means that it should go up today and it's not. That makes me think, what are the reasons?
