Lot of noobs traders , don't control their emotions and make worst mistakes : buy at high price and sell at lowest
how to control this ? = put orders (buy/sell) and close the platform
If you're new and you haven't had that much experience, seeing an invested coin drop dramatically in a dump definitely will make you panic. That happened to most traders in their younger trading days. In ine day it happened to me that i sold my coins for 25% lower than my entry price as i panicked watching the price crash down and reading the troll box. Later that day i'd find out that the coin eventually recovered and i could have earned 10% by that time. These things happen and you really have to learn from them to improve
