It is so impossible to trade without any single loss. But the thing is we can compensate every loss thru average down. So do not trade the whole money 100%. Always trade in portion. One more thing do not trade using margin if you dont know how to manage it.
Yes 100% accurate profits are not possible always. You need to face loses too some times. It is good because you will gain conidence after losing and you will start fresh.
Yes trading has two possibilities only,it's either you win or you lose.But losing in its way is not really a sign of negativity,it will even make you a good trader,more skillful than the previous.So do not be afraid to take risks,the only thing you need is to balance your way of thinking.Learn to hold those coins who are still worth keeping and sell those coins who are in peak.The only thing you want in the end is to make bigger profits so trade when you think its already its time.
