Expect to be paying $10-30 USD per day in the first week. You wont be able to sustain this if you rely on NET30 payouts.
The above features are just an estimation, We can sure balance the reward structure if needed.
Also let me mention that, i am using many adverts module built within the faucet to terminate payout issues.
We also have a login feature into it and a 4 layer deep Anti bot script that will stop 99.99% of the bots and proxy users.
Still, The Zbitcoin Hybrid Faucet will run for 40 days as a Beta model.
If our users maintain stability without any problem, we can make this one of the best BTC earning site.
