Trading is too complex an activity, because there is no one clear algorithm that would act the same way for everything. Therefore, every trader tries to create their own strategy that will work for them.
Don’t be greedy, it sounds too abstract, and will also depend on the trader’s strategy. And traders lose more than they earn for the reason that they do not follow basic rules, do not share the risks in trading, and even perhaps simply choose not the most reliable coins for trading.
Greed affects many traders today. Most traders don't really use strategies that suit their knowledge; all they look up to is money, which is not the case. As a professional trader, using your own strategy is very important as it will be a guide for you while trading and it will always favor you while trading, but greed is what makes some traders jump into the market without the fundamental knowledge of trading. Even though we all know that losing in trading is a normal thing that happens, if they lose too much, it will discourage them from doing so, and in this kind of situation, they will not notice that there is a course if they lose, forgetting that it was greed that was making them lose all the time.
So it will be good if all traders calm down and learn the key aspects of trading, such as fundamental knowledge, getting their own strategy, technical analysis, and some other key things that will help such traders.
