By the way, I used the calculator here: http://ncalculators.com/investment/short-term-savings-calculator.htm
and with a more conservative approach of only 4% interest per day, with an investment of 1000$ which is re-invested every 10 days, It will take a mere 180 days (6 months, or 24 weeks about) to reach Half (0.5) million dollars. From there, it'll take only 20 days to get to one million dollars.
Of course that's considering the enterprise will run this long.. but it's a daunting thought, to contemplate how compound the interest gets.

What do you think?
