The bitcoin what they are offering are far much lower than faucets , in faucets you can earn more than 25k bitcoins in 24 hrs , and the services what they are offering is through google search so cannot believe them that how many days they will stay in the market, untill they dont start their own search engine without taking help from other search engines.
Yes, but how many faucets work? and what do you have to do to earn them? Anyway to your other point, the app developers should build search apps for other things such as youtube, bing etc..
