>> Don't tie up your cash unless you have to.
What are you doing with your cash/profits that is earning a greater than 7% return each week?
Do you have another project has an even greater return? Or do you just like to spend money on consumer items?
I cannot think why you would put more into cash than enough to pay the minimum life essentials, if the alternative was to invest money at 7%/week. I'd not solicit new funds, pay off the original investors, and use my own money.
I don't know, my CPA should know, he should be making more than me right

No, in honesty. Vegas, Fast Cars, Private Islands and Parties... what else?
