Stop being greedy! Refer any faucet you can - all the commissions add up. It's less about the referral commissions available and more to do with the overall feel of the faucet - if a user likes it, they'll visit over and over. You can find a 250% referral faucet (it's called casinobit.in or something) - but the site looks horrible IMO.
Most faucets that offer this sort of commission will only do so for a week as an introductory offer, very few faucets can maintain this. The .xyz family of faucets, yourfaucet.net etc all offer 100% ref and have maintained it, but shifted their payments up and down.
I'm promoting all faucets that I found paying 1000+ rewards through my rotator.
I am looking for a good referral payer to fix his faucet in a highlighted spot in my site.
Anyways I totally agree with you.
