I saw a new site recently for a similar kind of faucet idea minus gambling but with adverts as the idea for an overall business I guess. The problem is you are taking a bigger bet if the newer site will carry on operating, if the site will really be a success enough for the operator to carry on. Most of the time sites come and go, if they exist after a year often its just become part of somewhere else or they discontinue the various offers. This site and other long term ventures have a better assurance in their longevity, if you get the referral its going to count for years (based on the quality of the signup, etc.), most places cant say this.
I've had some success with referrals but only short term offers, not this kind of deal unfortunately I've not got a larger following anywhere really.
The problem with fresh sites of this same kind is that they are replete of intrusive ads and pop ups, which may also contain malwares if the user clicks somewhere wrongly. Moreover the rewards are similar to the one offered by freebitco.in hourly, with the difference freebitco.in is a very clean, practical and friendly site.
What I most dislike about these alternative platforms is the fact they create internal tokens, so you have to accumulate some thousands or hundreds of thousands of those tokens to exchange for a few satoshis. They completely difficult the calculation of how much you are actually making by using the faucet to give a false illusion that worths the time and effort you invest on that.
On the other hand I could mention Cointiply as an exception to that rule, although their interest feature is inferior to Freebitco.in, as users' balances constantly fluctuates due to it not being in bitcoin for real, but in an internal token called simply "coin". When bitcoin loses value, you exchange your coins for more btcs, but when it rises in price, you get less of that from your coins.
