Reselling Humble Bundle games is generally disapproved of as the bundles are intended for personal use only (though gifting is fine) and the proceeds benefit charity, so you may not get many buyers. I found this out when I tried to sell a few of mine, but that was quite a while ago so YMMV.
However, I've bought a few keys from people in the past (and many more bundles directly; I enjoy the games, and the organizations they choose to donate to are definitely worth supporting), so you never know.
oh, ok, thanks. I am rather new to humble bundle, and really new to bitcoin. Im just trying to make my first little bit of bitcoin somehow :/
