What would you do if you had $86m? It's a welcome dilemma for some of bitcoin's early adopters thanks to the cryptocurrency's meteoric rise. One generous bitcoiner has decided to follow the lead of Bill Gates and establish a philanthropic purse, the Pineapple Fund. The founder, known only as Pine, declared in mid December I'm donating 5,057 BTC to charitable causes!" and since then has given away $7,550,000 in bitcoin to charities and causes around the world, with a view to dispersing the remaining bitcoin over the next several months. "I'm happy that I can help change the world for the better," Pine says in a phone conversation on condition of anonymity. The nine recipients of the largest bitcoin charitable donations are a collection of nonprofits including medical researchers, those providing poverty-stricken communities with basic necessities, and technology-related causes. "The $1m donation will support the work we do standing up for user privacy and free expression, and defending civil rights in the digital world," [says a spokesperson for the Electronic Frontier Foundation]. The collection of charities also includes Watsi, a platform committed to taking the US towards universal healthcare, the SENS Research Foundation that works to develop cures for degenerative diseases, and the Water Project which helps to establish safe water sources in Sub-Saharan Africa. Another $1m gift will help fund advanced clinical trials of MDMA-assisted psychotherapy for post-traumatic stress disorder.
