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 is good to buy those who are in red ones. It just clearly means that the price is low. For the meantime, buy those who are in red ones. Spent those money that you want to invest on red ones as they are what you are capable of investing. You can see eventually or there would be a timing when this coin will gradually increase and can give you a high profit. You just have to read the white paper for you to determine a good coin or a good investment.
