WikiLeaks' adoption of bitcoin in 2011 is again drawing attention as the first major case that showed cryptocurrency could be used to bypass blocks in traditional financial networks.

On June 14, 2011, WikiLeaks officially began accepting bitcoin, blockchain media outlet U.Today reported on Saturday.

The backdrop was strong financial sanctions. After the “Cablegate” disclosures, WikiLeaks was cut off from major payment and remittance providers including Visa, Mastercard, PayPal, Bank of America and Western Union. The move effectively wiped out about 95 percent of its operating income overnight.

In response, WikiLeaks published a bitcoin address and began receiving donations. The outlet described it as the first high-intensity real-world test of whether bitcoin could function as a “censorship-resistant currency”. It meant that, in a situation where the existing financial system blocks a specific group, a network that operates without a central entity began to be verified as an alternative in a real environment.

The episode also became a turning point for the bitcoin ecosystem. Before WikiLeaks, bitcoin’s ability to bypass a financial blockade was closer to theory. But as an organisation under strong pressure from the U.S. government chose bitcoin as a means of donations, bitcoin moved beyond a technical concept and was put to the test as a real payment method. The outlet pointed to the period as a decisive milestone for the cryptocurrency ecosystem.

The sudden exposure also became a burden for the early bitcoin community. Satoshi Nakamoto, bitcoin’s anonymous creator, warned on the Bitcointalk forum that WikiLeaks had “kicked the hornet’s nest”. Satoshi then voiced concern, referring to a coming “swarm of hornets”, and disappeared completely from public view a few weeks after leaving the warning.

In terms of market reaction, the WikiLeaks case helped spur participation by other groups and services. WordPress began accepting bitcoin payments in November 2012. The Internet Archive said in February 2013 that it was ready to receive bitcoin donations. The Wikimedia Foundation, the non-profit that runs Wikipedia, later added bitcoin to its donation methods.

The trend shows an early path in which bitcoin expanded beyond a simple online experiment into a payment and donation tool. The WikiLeaks case is significant in that it was not about price volatility or an investment vehicle, but showed what role cryptocurrency could actually play when funding flows are blocked.

The episode also shows that bitcoin’s spread was accelerated not only by the technology’s strengths but also by external pressure such as blocks in existing financial infrastructure. Given that multiple organisations reviewed or adopted bitcoin payments and donations after WikiLeaks’ adoption, the decision in June 2011 remains one of the moments when cryptocurrency first collided with the real economy.
