The Lifeboat Foundation, which claims to be committed to "protecting humanity" and is associated with prominent figures such as Jeffrey Epstein and Vitalik Buterin, has been on the Internal Revenue Service's automatic revocation list since 2020, despite its claims of 501 (c) (3) status as a nonprofit. The foundation has been accepting cryptocurrency donations since 2013. The first donation came from Brian Cartmell's 500 bitcoins, and currently holds a large amount of cryptocurrency that was not immediately converted into fiat currency. Donors include Jaan Tallinn and Charlie Shrem, who together received more than 1,100 bitcoins and 190 ethereum. At present, most donors are businesses that hope to improve their search engine rankings by displaying their names and links on their websites.
