I won't lie, I saw this drop incoming, I sold near $50k's and bought back at $32k, then sold at $64k in Nov.
The chart pattern which was forming was double top with bearish RSI Divergence in which RSI is was going down, Price was going up.
Once it came towards $48k, I was able to see it forming another similar pattern which happened in 2018 that it will touch $22k.
So I bought at $21.5k for 50%, and DCAing the rest 50% throughout the year.
How could you be that perfect in your chart reading? Interesting.
I am like when I really need cash then I take a good portion and sell. Many times I found myself, after selling some the market started to move up and up like 10x LOL
By the way, I am DCAing from long time. It was slow when the price was over $30k but now pushing it again.
