After the flash crash Ethereum has ratcheted up the $500 level after pausing in the $280 area for some time. Ethereum is not exhibiting the mania of Bitcoin.

The price is currently under $400 and it appears that the coin has been ping ponging back and forth in rotations as the big boys are ramping up their investment.
