The line in the bold should remain as the resistance line of ethereum. If ethereum cross or move beneath this line then correction period of ethereum may extend. Slow ups and downs will remain untill the mid of april, may be.
From the wave 5 it can be predicted that next mark is 585$. Now, upper trend line should be breached for the new highest of ethereum but it can got 2 or three months.
For a close view of it. The lower trend line is set to 517. The price should not breach the lower line. If it breach the lower line then we have different scenarios and predictions. Start of April is crucial for ethereum.
