Cancer Fairy Godmother is not a profit making company. In fact, it is not even a company at all, it is simply a website that was built to get information out to people coping with cancer who need some help.
This site was started by the late Tonya Sue Carther, built and hosted by Kit Latham to help her get the word out.
There were never any resources (money) to be able to file the tax paperwork to get Non-Profit 501(c)(3) status, so doing any real fundraising has been quite limited, even when it has come to the option of using pPaypal.
Bitcoin has changed the dynamic in this regard. We will take money to help fund the site through bitcoin at this time. We will be adding the ability to do this via Lite Coin, and Dogecoin in the near future.
