One possibility is that you are planning an investment that is very risky. If you are lucky, it will be good for a while but sooner or later it will explode and a lot of people will lose their money and hate you.
Another possibility is that you are planning something that is equivalent to a Ponzi scheme without realizing it. If you are unlucky, it will be good for a while but sooner or later it will explode and a lot of people will lose their money and hate you and you will go to jail.
