I just invested approximately $50 in freebitco.in to gain interest payments. Let's see how it is going to end up in a couple of years after btc goes nuts . Having a few satoshis automatically every day as a passive income sounds quite alright to me especially while this service is here for years. I pretty much trust freebitco.in. Not with all my life savings though, it is quite hard to gain my trust.  

edit: I also realized now after I made a deposit now I can get the full faucet bonus instead of %30 of it which feels great.
