Roger Ver, an early Bitcoin investor and promoter of Bitcoin Cash, is fighting extradition to the U.S. over charges of evading $50 million in taxes, mail fraud, and false tax filings. His legal team filed a lawsuit with the European Court of Human Rights, arguing Spain failed to consider legal uncertainties around crypto taxation. Ver, who renounced his U.S. citizenship in 2014, was arrested in Spain last year and is now campaigning to have the charges dropped, hoping for political intervention similar to past crypto-related pardons under Trump.

Elon Musk’s viral tweet criticizing U.S. authorities for inaction on the Jeffrey Epstein case inadvertently triggered a rally in Solana’s PNUT token. The mention of a squirrel named ‘Peanut’ led traders to associate it with the meme coin, causing its price to jump from $0.22 to $0.23 within hours. Trading volume spiked 80%, reaching $215 million, while market cap neared $224 million. However, experts warn that such gains are often short-lived, as meme coins lack fundamentals and rely on fleeting hype. Meanwhile, a leaked memo disputes claims of an Epstein ‘client list,’ adding another layer to the controversy.

The case highlights growing concerns over crypto’s role in undermining sanctions, with Gugnin facing up to 30 years per bank fraud count. The indictment reveals deceptive practices, including falsifying transaction details and using Tether (USDT) to move illicit funds.

Conor Grogan from Coinbase has uncovered 430 BTC, valued at $47 million, potentially linked to Ross Ulbricht, the Silk Road founder, after a decade of inactivity.

Grogan speculated on the availability of the private keys needed to access the wallets, while the crypto community reacted with mixed feelings about the implications of revealing this information.
