After my research and understanding I feel ethereum will certainly grow in adoption as it is building what I see as the next de facto platform for the web. However, Ethereum is not a monetary instrument. It is used as digital "fuel" for the smart contracts. Additionally, ethereum is infinitely inflational. Its not necessarily bad economically, but when approached as a monetary instrument this means ether will only grow in value when the demand for them exceeds the supply. And right now the demand is still far in the future when more platforms like augur, boardroom, and airlock launch and gain adoption, meaning any ether bought now is practically guaranteed to decrease in value simply through inflation.
