The problem is that people are still investing without any research of each project. Thats why there are so many scams around, because, unfortunately, investors are even too lazy to read the whitepaper or to check the team members.
Of course it is only experienced by Beginnesr investors where they are only interested in the profit mentioned not with the products or ideas that the project will launch. in fact many aspects they can do to avoid fraud but they don't.
Avoiding fraudulent projects on crypto is actually also difficult. although sometimes we are maximized in finding projects that we think are good but often also when time goes by the development that they do is apparently not acceptable to the community ?. this also includes projects that fail. their products do not go according to expectations and inevitably prices will also decline.
