I remember when I read a lot of TA that said "if 400 is broken, its all over."
So I sold at 388, and sold on Coinbase, waiting for the money to get back into my bank.
Watching it rise the following week was one of the worst feelings I've ever had.
Yes, it sucks to watch it drop. It is 10x worse to watch it rise after you've sold.
Just my experience on this.
Investments don't pay off in 1-2 months. They pay off in 5-10 years.
