You just don't take any decision from any one on forum or internet just to cash out without doing your own analysis. On what basis will some group of people fud about a coin so all do panic rewarding? If you are a season trader you just don't wake up and make trading decision base on what the populace is chanting.
Making a decision from what we read without making analysis will be dangerous for everyone because they don't know what the real happening. That will be too risky for us because we could end up by losing the money we use to buy the coin. We don't know why they do that thing, but the only reason for them to do that will be to make people panic so they can take the profit from the news they spread.
They take advantage of the panic that occurs to buy low, understanding the news is indeed very good but if we eat all the news without any research done on its own then it will also be a loss in the end. There have been many communities here who are always reminded to do their own research and that it is solely for their good too to know what really happened before making a decision in trading.
