Certainly you are correct. Except I prefer to buy (preferably at lower prices) and hold.
I find it amusing, though, how people get euphoric at short-term gains, then panic over the inevitable correction.
"OMG the stock market lost 10% today!"
"Did you sell?"
"No."
"Then why do you care? Doesn't affect you - but probably you should buy."
"Uh...never thought of that."
People are silly. :)
Absolutely agree with yah, Bitcoin bullrun has a trend. There will be correction everytime it hits the ceiling. Following this trend and using the buy low - sell high method, we can maximize the profit.
