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?
Actually, if you really pay a much closer attention to it, you should not only take into consideration whether the market is red or not. Generally, it is much better if you buy during the dip. But since we do not know how severe the dip is, then you will consider whether it is only a specific coin which is dipping or the entire crypto market. If it is only a particular coin then a 18.74% dip is already a very good buying time, provided there is no serious reason causing the dip. But when the entire market is really going red, it is wiser to wait for a longer time. 18% may be the decrease in 24 hours but the next day, there will be another more severe one, and the day that follows.
