i was always told to buy in the red, but if that's true is there a certain % when it's in the red i should buy. For example on binance 24h Chg% xxx coin is -18.74% is that too low? or should you buy in the -3 to -5% range?
It will be easier to gain profit when market is green, then we should sell it in the right time, "don't hold". After the price of bitcoin rise then the price of bitcoin will fall. That is what always happens, actually it is depend on our strategy.
