Ethereum is a joke now. Nobody thinks it's a serious, long term player anymore. It's appreciated in value solely because of Bitcoin instability and DASH pump. It can't sustain this price level, period.
I don't trust Ethereum one bit since it's shown to hard fork under centralized control. However, I never expected it to be pumped up so much. The whole "consortium" thing makes people fall for it, while The DAO showed smart contracts don't work because nobody understands the contract. Since smart contracts were Ethereum's sole USP, there's no reason left for it to exist.
And then there's the $4.6B market cap that proves otherwise. I don't think it has the long term "holders" the way Bitcoin has, while it's certain the creator owns many coins. Once the dump starts, I expect it to drop hard. But it can take long enough to go bankrupt trying to short it.
