That's why its important to use money that you can afford to lose so such feelings won't come to you when you're losing your money in a scam project. I once felt that when I lose my money in a project that becomes a scam after a few months of running cause when I did research the project is looking promising and had decent progress, I end up investing 500$ in that project and after few months I lost all my investment. I feels desperate at that time since its not money that I can afford to lose but I made that experience as a learning.
