Just like Bitcoin Ethereum is going to go up for a few month. There will be a correction afterwards which will push the price down to $350. after this correction there will be an uptrend which will break the all time high of $1400.
current wave might take some time to fully develop. after that an upward corrective move is expected. invalidation level for this pattern is not clear at the moment and the pattern needs more time to develop.
side note: looking at bitcoin chart and other altcoins, shows that the bullish market is not over yet, and crypto markets will stay bullish in Q2~Q3 2018.
