If you are looking to start a faucet, me as a faucet user would suggest you FaucetHub.io micro payment system. There are more features on FaucetHub.io which make us be able to earn more profit from this activity. I can't say for the most faucet users, but for me FaucetHub.io is the best and substitute FaucetBox with advantages.
