If you let the coins build up by doing multiple withdraws from CMG you’ll be able to withdraw your coins from FaucetPay to your main wallet in no time.
Wrong.
First of all it takes the same time building up coins at FaucetPay as it takes building them up at CMG, because coins do not become more by moving them to a different place, and then you need some extra coins to pay the secondary withdrawal fee from FaucetPay to your wallet.
Or in other words, the detour through FaucetPay takes a bit longer and you get out a bit less.
