Yeah I know a good faucet script costs more than 25 dollars . I will pay more if the script is really nice and if its free from bugs.At the present scenario investing a hugh amount in faucets is really waste.
If you are willing to pay more for a good script then you might want to set a higher budget from the start. And I agree, investing a huge amount is a waste. I would go as far as saying investing any amount is a waste if you can't get adsense.
The only ad network that pays a decent amount is mellow ads. But to get accepted by mellow ads you need a high alexa rank. To reach that rank for the first few months I have to pay satoshis from my pocket .Thats why I am trying to get a script for small amount.
I don't know about everyone else but from my experience mellowads is worthless. I owned a faucet with the same hope of making a high alexa ranking whilst paying out satoshis from my pocket only to be disappointed. Maybe mellowads paid more in the past but as of recently I was making more btc from a-ads.
