If you were digging the old 'no work free money' concept of bitcoin, try some of the altcoins, specifically the newer ones. There are plenty of faucets still available for coins other than bitcoin, if you can guess which one will be worth something in the future 
If i have the slightest idea about which will be the next big thing then i would invest my entire fortune in it without a second thought. 
The problem with all the alt coin is that you never know what will happen to them in a few years,the possibility of growth is not that bright as bitcoin ,but you never know what will happen in a few years.
