In situations like this I like to have my main position and have a smaller position (0.25 BTC ) to play with to allow me to constantly dollar cost average, so when we do get the those big moves up I am maximizing on profit potential. ie with this smaller position bought at $44.3 sold at $45.3, it's a few hundred dollars profit but constantly doing it adds up.
I am hoping (I am often high on hopium) we see a big income of money and take us all the way to $52k, if not, will add on the way down. $42.5k could act as a major support, if we do reach there, will add even more at that point.
From my experience and speaking with hedgefund friends, it's conclusive we are in a completely new bull faze, don't miss this opportunity. DO NOT PANIC SELL, never do this. Remember with crypto, it can be declining for weeks and within a day it can blast through and take you back into profits.
Try to not trade with emotion, if you find yourself trading with emotion, lower your sizing.
