[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.
Greed may sometimes be useful in some ways, but mostly, when you come to invest, you should never be driven by greed, or simply just learn to control it. Because its part of being a human, so eventually it will always develop no matter what, but as long as you can reduce or control it, then things will be fine. However, when we are in crypto investing, we should always take time to sell when the prices of the coins have increased a lot, that way we will sell in profits, not with losses. Because knowing the market is so volatile, the prices will eventually drop down without us knowing so better sell them when there are good opportunities to sell.
