That might be true. But I do not believe Ethereum will be able to hold their gains for long. Sooner or later the price has to go down simply because that is what markets do.
So always remind yourself not to get lost in the mania and try to stay objective. In a market like this, it is easy to think that the good days will never end.
Ethereum is under a massive bubble due the ongoing ICO frenzy where everyone wants to buy into the next %1000+ performer. They all need ETH to buy into those ICOs. The Bancor ICO is today so it's clear that this is helping into keeping ETH on the green while BTC dips and so do the rest of alts.
