You mean faucets? They get ad revenue from the ads. It's not a lot but they don't pay out much either. Gambling sites have a house edge (typically 1%) so over a long period of time and across many bets, the site expects to turn a small profit.
Yeah, the revenue model behind faucets included. How does the owner of the faucet website establish the relationship with the companies advertising?
Also, what is the actual ad revenue vs. cost of users solving CAPTCHAs? I'm sure there is a range, but I'd be interested to know. I'd also like to know what % of CAPTCHAs actually click on an ad, and then what % of ad clickers would actually make a purchase.
The best thing is when I actually met up with a guy who also shares the same interest in bitcoin and I find that talking face to face with him also helps me to understand on a lot of thing rather than just reading alone.
Always amazing when that happens.
Anyways, very diverse range of events and experiences so far sparking the initial interest in Bitcoin
