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. 
This is obvious, the market is very illiquid and the main coin sets the trend for the whole market. In order for this not to happen, it is necessary that capitalization increased to several trillion dollars and the bulk of altcoins had trade pairs to the dollar. Personally it seems to me that for several more years the market will go for Bitcoin.
