Yeah right, I just see that other coin coins follow only the bitcoin movement, when the bitcoin price falls, the other coins also fall, and vice versa. The only example is Ethereum, the current popularity of ETH should be able to boost the price to equal the bitcoin, but in fact the price of ETH just follow bitcoin.
This is because most of the time other coins are bought with Bitcoin. As more Fiat coin pairings become available then BTC should not have as high of a correlation with altcoins like it does today. Bittrex is taking a step in the right direction with this.
