Im doing day trading in a big and very popular exchange. when im starting to trade in the particular token. the green candles is going crazy filling up and because i was not ready at that time i feel the FOMO thats why i buy too until my internet connection has a problem thats why its lagging. for a minute when i refresh it. the price was dump already and followed by red candlestick i was left a bag holder. since i have no choice i have to sell it at losing price. ive learned that FOMO was not good at all times. What are causes of this??
