I'm not sure if the mining is paying out now. I did little over 300,000 hashes. Is that enough for anything?
Should give you a few satoshi. Now the amount given should depend on btc price, so it may have lowered these days. Two weeks ago with 1 million hashes I got around 200 satoshi. 
when did they start mining ,i heard they have an investment sharing platform they started recently but what is this mining thing you are talking about,this is one of the oldest faucet site still running and i am glad to hear that they are changing with time with new upgrades to keep things interested.If you log into freebitco.in the first thing you'll see is their mining notification (either directly above or directly below the interest notification). It uses browsermining to allow you to earn coins that are converted to Bitcoins.
