In an anonymous effort to help secure Julian Assange’s freedom, an anonymous Bitcoiner donated over 8 Bitcoin, worth around $500,000, to help Assange’s family pay off the debt incurred by his charter jet and settlement expenses, CoinTelegraph reported.

On June 24, Assange was released from the high-security Belmarsh prison in the United Kingdom after reaching a plea agreement with U.S. authorities. Shortly after his release, he departed the U.K. on a private plane from a London airport to Saipan in the Northern Mariana Islands, a U.S. territory.

Assange appeared in a district court in Saipan on June 26, where he pleaded guilty to one charge of breaching the U.S. Espionage Act by leaking classified documents. The journey was planned to prevent Assange from touching foot on American soil.

In an interview, Stella Assange, Assange’s wife, stated that “freedom comes at a cost.” Assange is required to pay $520,000 to the Australian government for the “forced” chartering of flight VJ199 to travel to Saipan and Australia. Stella started a crowdfunding page to help the jailed founder with his debts after his return home to Australia.

The donation link was posted by Stella Assange on June 25, and within 10 hours, an anonymous Bitcoiner paid over 8 Bitcoin to the fund, almost clearing the goal of $520,000. He has also received over 300,000 British pounds ($380,000) in fiat donations so far.

The single Bitcoin donation was the largest donation to the fund, more than all other donations in all currencies combined. As a result, Assange will arrive in Australia debt free.
