Hi munayam,
Is there any other way to do that?
Like I have a crowdfunding website and whenever some investor invests some amount in a compaign, I want to fix a rate of interest that he will get on the invested amount (% of interest rate to be fixed by admin only). Suffice it to say, I want to add rate of interest just like rewards in a compaign. Kindly, let me know if there is any other way to do that, even if that can be done through coding. I will really appreciate your help ??
