just look at the prices. Etherium is seeing major resistance around $200 - $225.
Also GNT/ETH is at a trend low. With such a run up in the last 24 hours and market cap does not seem to be increasing I can't see how Eth can maintain these prices over the next fews days. Long term I think ETH will easily go to $350 or higher. Short term it looks ready for a technical correction.
