Well, it's a basic advise but it's on of the most important. And i think it need to be seen by new people and be reminded for those who are long time in crypto world. Because you can easily forget about basics at some point.
Everyone has emotion at every trade they engage in, but the we handle it differently with experience we have all gathered in trading.
I was watching a video of YouTuber who lost 100k of his leverage position, it was 3x actually but the market didn't goes as plan and he was mad that he should have listen to his body language and emotions when the market wasn't going as planned but he refused until he woke up to margin calls that his position has been liquidited, this happened when the market is usually vatile.
