Greed is really reasons why many of us the traders lose heavyly in trading. I have read many stories on how many people have make great profits from their cyptocoins investment and one thing I have find in common is that there are not greedy people, their invest with open mind and into something worldwide. Many has also lose their hard earned money through investment because of greed and fast profits ideas.
This is the case everywhere, not just in crypto. People somehow think that it's possible to achieve great things with no effort. That's simply not true. Sometimes you get lucky, but in general you have to put in time and focus to actually get something back in return.
The people who really know what they are doing (because they spent a lot of time analyzing all possible outcomes) who actually share their ideas make it seem easy to those who don't have any clue. And then they get trapped in thinking that you can just jump on a hype train and end up successful. Successful people think very carefully about the opinions and assessments of everyone around them, but they don't let those opinons persuade them into doing something they don't fully believe and understand themselves.
While it takes time to make a fortune in Crypto, it's not really difficult as long as you keep your mind open and keep asking yourself a lot of questions. The same is true for everything else that can be learned or achieved.
