If you happen to check the Earnings Wallet, you're going to see some transactions where BTC is sent to this address: 1CtcbAj3mHLU2nbf1jGBVdSDrVdTnEkeFk. When I set up a few of the HYIP programs, I used the Earnings Wallet for withdrawals instead creating a new one. This wouldn't pose a problem, except that the payments include the principal, which shouldn't be used in the dividend calculations.
Because of that, you'll see me transferring all future withdrawals from HYIP to the new address. For each weekly payment, I'll send the appropriate amount of BTC to dividends from the new HYIP address, and then issue the dividends.
