Sounds advice. This could very easily be a temporary blip and the continued downtrend can start right back up with a drop of 20% in a day. That is the crazy part of crypto.
What I have been doing is buying large dips which tend to then be followed by a small rally. Sell the rally and then rebuy the next large dip. Was in at 6400 and back out at 7800. Missed some profits, but have done this 8 times on the way down and each time it's added to my cash position for larger purchases the next time.
Always need cash on hand to capitalize on market corrections!
