$1.25 - 1 token per month
Good karma. Yes, for each token you donate, you will possibly up your level of good karma. Your kindness will potentially improve you existence.
Note: I do NOT promise you will receive improved Karma, but it may be worth the try. - Donate 1 or more tokens for absolutely nothing in return. Take your time, and make your decision wisely. Research has shown that giving makes us far happier than receiving. Maybe you should put this to the test and see if that research is true or false.
