Should people be held responsible if they lose money by investing in a fraudulent crypto project?

I believe they should take responsibilities for it because the ultimate responsibility for an investment lies with the investor. However, there are cases where innocent people without enough knowledge or caution are deceived by sophisticated fraud schemes. That is why governments or local governments should monitor such cases closely and actively share information through television, social media, and other channels to prevent further victims. At the same time, as fraud techniques continue to evolve and become more sophisticated and cleverer, it is inevitable that some people will still fall prey to scams. Therefore, it is most important for us as individuals to stay alert, protect ourselves, and also look out for those around us by sharing real cases and warnings with each other. Through our combined efforts, we can drive economic deception away from us, leading to safe and sustainable society where members live in harmony.
