How exactly will the 50% ref back work, if my chosen payment is not the chosen payment the person I refer picks?
If the referral and the referrer use different currencies, conversions will apply.
Example: you are using the paypal faucet (USD) and you give your referral code ABCD to your friend, but yout friend logs in to the faucet with his BTC account.
He gets , say, a 0.000002 BTC dispense, and you win the 50% that is 0.000001 BTC converted into USD.
The conversion is done with MtGox rates.
The site internally uses MtGox API for BTC/USD conversions and Cryptsy API for BTC/LTC and LTC/USD conversions.
I've fixed the grammar error, thank you
Why would you still use mtgox?
isn't that thing going down?
If you know a better API for BTC/USD let me know, maybe CoinPayments API?
Cryptsy does not have BTC/USD, only BTC/LTC
p.s. Cryptsy does not even have LTC/USD ratio, i find it by combining BTC/USD from MtGox and BTC/LTC from Cryptsy

choose one that you like but don't include mtgox as that price is irrelevant!
