I am not really sure if you are messing with me or are you serious. Do you realize that FreeBitco.in is one of the biggest Bitcoin related websites, right? You seem smart enough to understand that if you are one of the biggest players you are in the completely different situation.
Have you ever wondered why is Google Adsence so popular and why they can pay what they are paying?  Because they are biggest Ad platform in the world, second biggest is Media.com and they will hardly pay you 25% of Google Adsense? Why is that? Hmm, they are second biggest, so they should pay almost same money as Google or even more, right?

Do you know why some faucets have no cooldown period? Because they are paying a very little amount of money and they know that its so annoying and full of ads, that you will soon or later give it up, if you are not crazy crazy.

I don't wont to sound rude or to tell you what to do, but I think that you are missing some important information about this whole situation. As you may notice I run also classic faucet for a few months already, in the begging you could claim coins only every 90 minutes, but after some time I have decided that I will change it to 33 minutes. And guess what, even you could claim 2 times more in 99 minutes, in the end I paid out less than before and I don't think that I would have a drop-down in a number of visitors.

Most of the faucets will hardly survive longer than a month.
