Most people fail in trading because they do not seek proper knowledge about trading and they do not trade according to a plan. To trade you must have a very good understanding of its process how it works and the various coins in the cryptocurrency market. Another reason for failure in trading is lack of patience. Because if you are a newbie trader then you may face losses instead of making your profits in the beginning, but still if you stick patiently you will hopefully succeed one day. After trading, your mistakes will teach you slowly. So know well and stick to it.
Misconception, thinking that trading is just an easy venue to make money most newbies thinks that they can do it as same pattern like gambling, just plae you position and wait for luck to back you up and move it to your direction, instead of searching and studying the right way of trading, there are many possible patterns to follow as internet provides information about this business, without doing the proper idea will lead you to lose most of your attempts.
People who fail at trading often make common mistakes such as being overconfident, greed, refusing to take profits when they should, failing to learn from their mistakes, repeating unsuccessful methods, refusing to accept corrections, not knowing enough about the market before beginning, being impatient and disobeying instructions, believing they always know the best way to trade, and lacking self control or discipline.
Before some of them realized their faults, others failed due to a lack of knowledge and understanding that they acquired via experience.
All the things that you have said are right but the question is why they continue doing these things even though they know this is not right.
And this is what it only means, these people are not meant for trading...I don't think they don't have knowledge about trading nor we can say they don't have an idea of what they are doing but they probably doing this without passion and dedication. Because it was different when your goal was not only about money as certainly, we are willing to change and adapt to the market situation.
You need to have that focus, and like what you said, dedication and passion that will give us that mindset to continue adopting and adjusting if it's needed, you will not stay with one strategy but you will always keeps on studying what patterns is best fit to what the market is bringing, you need to anticipate the market so better to set proper adjustment to make things works for you while you have
your position.
