I am trying to earn Banano, there are many options to earn but I chose Folding@home to help in medical research.  I observe that having 100 points can only give us around 8-9 Banano.  Not bad considering my PC if left folding can earn around 9k points for the whole day.  Though I do not know how much would Banano cost in the future but having it around won't hurt.  Besides I am helping in scientific research.
