In coin trading, you are your only enemy. There are no rules in this arena, only you facing you, and you are both winner and loser.
People may think that they are fighting with the market, other investors, or those scammers shark that always have their eyes on your money. In fact, you are fighting against yourself. You are the one who made the decision. You can decide yourself to lose or win, trust me.
As human nature, we all want to make a bunches and make it fast; too much temptation that incites us to gamble with our account.
In the end, only you can chase off the temptation to follow the plan.
I disagree, yes you need to improve yourself and take better decisions everyone knows that but you are in fact competing against other investors, maybe you are not seeing them directly like you could in a different sort of competition like sports, but make no mistake you're competing against them if they win their wins lower the chances that you get profits, and if you lose you improve their chances of making profits.
