If you look closer at the different markets on coinedup, you'll see every coin's price has dramatically fallen for ten days. Not only Etoken (Even if Etoken moreover suffers Mogui's dump). Investors are gone at the moment, because Bitcoin's value is temporarily fluctuating (due to mtgox issues). They try to make some money selling bitcoins for fiat, and buyback when price is low. I think once bitcoin's price is stabilized, investors will be back, and price of every coin will grow, including Etoken. For now, we have just to wait.
And thanks for the hard work of the new dev team.
