If I may tell you that you are not going to get anywhere with spending $4 dry bucks
you better to spend $200 in the first 2 weeks of your faucet by paying a considerably big amount for each faucet claim and really pay at the end that way you could always depend on users to come back each day.
But be my guest and keep doing it your way.
Since the bitcoin price is quite high and faucet these days pay very less. If the OP can give good faucet rates he can attract the whole faucet community towards his faucets site. That is much better plan rather than just promoting.
