Although not technically a charity, Wikileaks is an official non-profit and has been accepting the digital currency before crypto adoption was even mainstream.
Because of the controversial nature of the content on WikiLeaks, large corporations put a block on all donation money coming in – leaning on major credit card institutions to block all payments going to the controversial site. This actually demonstrated one of the first major uses and benefits to cryptocurrency – since unlike traditional money, nobody could stop Wikileaks from receiving crypto donations.
In June of 2011, they began accepting bitcoin and from 2013 to 2016, it received the majority of its funding from Bitcoin and Ethereum donations.
In October 2011, Assange said that the financial blockade of Bank of America, Visa, Mastercard, and PayPal, had cost WikiLeaks ninety-five percent of its revenue.
