Dumping my coins if I see the trend in the market is dumping, investors will not dump if they did not see something wrong on the project, the developers could be out or the roadmap is not happening or people find out that the platform is none existence worse thing that you could happen is if you did not dump at the right time.
This is what I think! I will dump my coin if I see there is anything wrong. Investing is not easy, doing good researches help us to filter good projects to invest. However, it can't guarantee for the long-way. Instead, we have to follow along the team and their updates to know whether they're leading the projects in the right way or not. If I have any doubt and others think the same, I will dump my coins immediately to reduce the risk!
