As a crytpo trader your aim is to make profit from every of your trading, you may get carried away when you see a particular altcoin showing consecutive bullish candles, let say litecoin(LTC) rises from 16000 satoshis to 18000 satoshis, and it still looking as if its going higher and getting more bullish, and you pump, cos a reversal might just be at the corner, and then the bearish candles begin to flow and then you end up running to loss.
Morals : Stay patient, study the lows and highs of every altcoin you intend to buy before setting your buy target and sell target.... Stay profitable...
