I have not seen a trader that do not lose sometimes, i may be new to the forum but been learning before now. it has nothing to do with sentiments but traders have to learn to accept trades the way it is, without attributing loss to any factors; as it leads to more rekts.
Always accept the market as it is without blaming any factors.
Always dyor too
Accept and move if you loss high profits on trading, many traders always hold there coin they think that it make them profit more but, suddenly it drops. When im trading i always trade it even i have have small amount of profit because you will never predict what will happen next on the market, i don't expect much to earn but still i earn. I also loss some of my profit this past but accept it and learn from your mistake.
