Yes, If the bitcoin reaches 1,300$- 1,500$, I will sell 70%-80% of total bitcoins because I have a big profits (about 80%-100%).
and then I will wait for bitcoin going down at 650$-750$ to buy it again.
all this stuff is still being made up as it goes along. they said bitcoin could never go below its previous all time high. it managed that just fine. i wouldn't go making presumptions based on past behavior. there ain't enough of it.
you could well be right. then again...
