Lots of similarities in the structure and cycle type of pattern on the weekly chart, i found it interesting for study purposes. Even Rsi is very similar as a possible confirmation. Yes it could be the buy opportunity of the decade for Ether, but it is a very risky bet, stop loss needed or no hesitation to manually sell if plan fails, don't get attached to your coins.
3Day candle chart confirms the same behaviour with Ether starting to (possibly) reaccumulate right below the blue MA
In the right chart the bull run lasted from mid January 2011 to mid November 2011 about 300 days and the recovery from mid April 11 to mid June 11, so about 150 days. Do you think for ETH now it will be the same ratio? Then the next bull run would start mid April 2020...
