From an investor's point of view, I think that bitcoin has very significant advantages over the ethereum coin. So the speed with which the price of the coin decreases, the ethereum is very alarming.
Why is that? Bitcoin is super 1-dimensional, if it's utility value as a currency doesn't improve, its price does not change. Whereas Ethereum can improve in several different dimensions, e.g. scaling, crypto utility, smart contracts, ICO tokens etc. Bitcoin has fewer routes to grow, Ethereum has a lot.
