Ross Ulbricht, founder of the Silk Road darknet market, has reportedly received 300 BTC from a source linked to the Jambler currency mixing service, according to on-chain analyst ZachXBT. The transaction involved addresses that had previous exchange activities in 2019 and significant deposits to Jambler between April and May 2025. Compliance tools have flagged some of these addresses, raising concerns about the legitimacy of the funds. ZachXBT suggests that the donation does not appear to be self-funded, highlighting potential compliance issues.
