Of course, you yourself are responsible for your investments. The project may lose its funds at any time and so do you, so before investing, check the project so that you do not complain about your failures.
I think that this is generally nonsense, if a person cannot see his guilt in his failures. Any action or inaction is primarily a persons personal choice, so it makes no sense to talk about how strongly, for example, someone agitated to invest in cryptocurrency, because in any case, everyone made the choice himself.
