This will work with any initial amount but I have used $500 as initial deposit. I feel the only way to make money is by putting money in. I never rely on referrals, as I never risk referral commissions that I may get anyway. I donate it.
So as you can see, before the end of the 13 days, you have your original deposit back, then you just do whatever you wish to do, but I risk the next four deposits then take for myself again. My plan is to continue with this as highlighted here. The only snag will be if payments don't happen before you have to upgrade and surf the next day. However at the moment things seem to be moving along nicely.
I have completed day 2 and have been paid for earnings, I still have 24 hours to upgrade surf, then at next server time, surf and request payout.
