Thank you Vitalik 
Ethereum has very valuable function with smart contract. Dapp that can be created will be useful in our real life,that's why ethereum has good price. Most ICo use ethereum tokens, it means that ethereum demand is higher than other altcoins. Since there are no competitors that have the same value with ethereum, the price will be higher in the future.I agree but higher once theres been a Eth crash? Alot of ICOs are over valued and attached to Eth Blockchain - weve seen crashes in Bitcoin, Litecoin a few years ago but Eth being so early im sure will have a similar story somepoint soon?
