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 like the "you are fighting against yourself" concept as it's really the nature of the trading. Your own greed, emotions and control. This is really the key. You can't win a battle if you don't know yourself and neither you can't win over you.
