[5]. Don't be greedy:The master of it all.
Greediness can reap you off all your profits already gained from the market when you're trying to gain it all. Be comtempted with the profit you've got and have plans for profits taking.
This is one the biggest challenge I faced during my early time of trading and even now but it's reduced and controled.
True, when we are too greedy for big profits then we will regret it, I often get when trading there is an opportunity to sell when the price skyrockets to thousands of percent, unfortunately I thought that the price would continue to rise but what happened was the opposite, it dropped more than 90% and continued drop so I lost the moment to profit.
Almost all traders I think have experienced something like that and maybe it is a good experience for the future not to be greedy,
even though at that time of course we felt sorry for not taking advantage of this moment to sell,
maybe if we do some research and analysis it will help to make a decision
