Well I think most of us have that fear. Of course we want to make sure we invest on the right project but sometimes its inevitable to encounter such despite of the research that we did. The good side is we learn from that mistakes and aware of what to do the next time we look for a new project.
mistakes and failures in choosing a project I think of course will provide experience for those who are still curious and like the crypto market. but for those who feel cheated, they will soon be out of the crypto market with losses.
