The time I started trading cryptocurrency , it's really difficult to control emotions and always there is regrets once I sold at a lower price and suddenly the price goes up drastically. But after I understand how trading and investing works I slowly manage my emotions and focus on the market movement to avoid unexpected loses. Trading and investing is full of risk but it is also our key to gain huge profit. Become a good investors just need patience, and self discipline including on how to control and manage our emotions.
True, i experienced the same thing the moment i started trading. There were so many times that i already keep an eye on certain coin, but my greediness and unexperienced emotion want to keep waiting its price to be lower, and lower, since at that time the trend is bearish. However suddenly the price went up, hugely that i regretted it immediately. If only i buy at that time, i would still gain profit. but now i have to buy it in a higher price than before. Surely, trading needs us to learn more, understand the market and know how to control out emotion and greediness. Then we can avoid loss and gain profits from trading.
