Did a bitcoin donor pay for Julian Assange's flight to Australia?

As a practitioner in the realm of cryptocurrency and finance, I'm curious to delve into the potential involvement of bitcoin in the recent controversy surrounding Julian Assange's relocation to Australia. Has there been any credible evidence to suggest that a bitcoin donor funded Assange's journey to the country? This query stems from the intersection of cryptocurrency's anonymity and the high-profile nature of Assange's case, raising questions about the potential use of digital currencies to facilitate such a significant move. Clarifying this matter could provide valuable insights into the intersection of digital currencies and high-stakes political events.
