These two are always the factor why people always end up losing huge amounts of money in trading. Sometimes our greediness strives us to do something that later on we will regret doing it. Not all of us can handle our emotions especially if we're already suffering from big losses, and when it comes to my trading activities I always set aside my emotions because I know it can be a hindrance to my trade or investment decisions. Based on my experience in trading, we should not stop learning something new and keep on learning until you totally manage to minimize the risk of doing trading and just stick with the coins that bring you good profit and never ever invest in shit coins or projects.
