Even IF Ethereum falls more in its price, it will not mean that this is the end of this cryptocurrency. The market capitalization of ETH is great, and it seems to me, it is even growing now. Simply do not worry.
Well, it's not easy to coin eth so early, I believe this coin will be the main coin in the money-market, they're pretty popular today, whether it's low or not. It is only a little bit difficult in this moment, we are investors in ETH should be patient.
