Look, it's easy.
People want tge grey scenario (super low, up, down) ---> 5% chance.
People want the black scenario (double high) --> 60% chance
People want the blue scenario (higher high) --> 35% chance
So..
My strategy is to sell 75% of my alts value once Ethereum touches the high, goes down and bumps back.
I will keep 25% in case we see an extra melt-up (to be sold). If not, I will sell the remaining 25% at the lower low.
