The chart looks very good. But, first of all, you need to check the development of the price of MANNA. You can see an indirect correlation and it's logical. The more people approved for distribution the lower price of MANNA. Yeah, if you haven't referred anybody, probably you don't make any money despite the fact you earn MANNA every week on your account.

But I still support MANNA as I hope you'll find more donors:
