I open an investment fund!

Hello! I have a question for you and I will be very happy if you comment on it.

So, I've been following HYIP projects for a long time and earning high interest on them practically without losses. And so I thought - what if to open a fund that can help people who are not versed in HYIP projects, not to lose their money and earn money there? Moreover, the investment fund will allow diversifying profits and significantly reduce risks.

At the moment, I get to earn about 30% a year from the amount of investment. What do you think, what percentage will suit potential investors?
I will be very glad to your comments and valuable advice!
