The Office of Foreign Assets Control (OFAC) of the United States Department of the Treasury has added a crypto wallet allegedly connected to a major international crime syndicate to its list of Specially Designated Nationals.
In a Sept. 26 announcement, the U.S. Treasury said it had sanctioned 10 individuals, including many tied to the Sinaloa Cartel. Among those added was Mexican national Mario Alberto Jimenez Castro through an Ethereum wallet.
‘[Jimenez Castro] reports directly to a Chapitos deputy and operates a money laundering organization that uses virtual currency and wire transfers, among other methods, to transfer proceeds from illicit fentanyl sales in the United States to Sinaloa Cartel leaders in Mexico,” said Treasury. “Jimenez Castro has directed U.S.-based couriers to pick up cash in the United States and deposit it into various virtual currency wallets for payment directly to the Chapitos and for reinvestment in fentanyl production.”
According to data from Etherscan, the wallet had a balance of roughly 0.018 Ether (ETH) — $28.22 — at the time of publication, with the latest activity more than 200 days ago. No other wallet addresses were included in OFAC’s most recent sanctions, which the Treasury said were in response to “illicit fentanyl trafficking” affecting the crisis surrounding opioid use in the United States.
“Today’s actions show that Treasury and the Administration will continue to relentlessly target the criminal enterprises threatening international security and flooding our communities with fentanyl and other deadly drugs,” said Brian Nelson, under secretary of the Treasury for terrorism and financial intelligence.

Many industry leaders and policymakers criticized the Treasury’s actions against Tornado Cash. Six individuals backed by crypto exchange Coinbase filed a lawsuit against Treasury over the sanctions, but in August, a judge largely sided with the U.S. government in a motion for summary judgment.
Satoshi Nakamoto, the pseudonymous creator of Bitcoin, marks their 50th birthday amid a year of rising institutional and geopolitical adoption of the world’s first cryptocurrency.
The identity of Nakamoto remains one of the biggest mysteries in crypto, with speculation ranging from cryptographers like Adam Back and Nick Szabo to broader theories involving government intelligence agencies.
While Nakamoto’s identity remains anonymous, the Bitcoin (BTC) creator is believed to have turned 50 on April 5 based on details shared in the past.
According to archived data from his P2P Foundation profile, Nakamoto once claimed to be a 37-year-old man living in Japan and listed his birthdate as April 5, 1975.
Nakamoto’s anonymity has played a vital role in maintaining the decentralized nature of the Bitcoin network, which has no central authority or leadership.
The Bitcoin wallet associated with Nakamoto, which holds over 1 million BTC, has laid dormant for more than 16 years despite BTC rising from $0 to an all-time high above $109,000 in January.

Nakamoto’s 50th birthday comes nearly a month after US President Donald Trump signed an executive order creating a Strategic Bitcoin Reserve and a Digital Asset Stockpile, marking the first major step toward integrating Bitcoin into the US financial system.
Nakamoto’s legacy: a “cornerstone of economic sovereignty”
“At 50, Nakamoto’s legacy is no longer just code; it’s a cornerstone of economic sovereignty,” according to Anndy Lian, author and intergovernmental blockchain expert.
“Bitcoin’s reserve status signals trust in its scarcity and resilience,” Lian told Cointelegraph, adding:
“What’s fascinating is the timing. Fifty feels symbolic — half a century of life, mirrored by Bitcoin’s journey from a white paper to a trillion-dollar asset. Nakamoto’s vision of trustless, peer-to-peer money has outgrown its cypherpunk roots, entering the halls of power.”
However, lingering questions about Nakamoto remain unanswered, including whether they still hold the keys to their wallet, which is “a fortune now tied to US policy,” Lian said.
In February, Arkham Intelligence published findings that attribute 1.096 million BTC — then valued at more than $108 billion — to Nakamoto. That would place him above Microsoft co-founder Bill Gates on the global wealth rankings, according to data shared by Coinbase director Conor Grogan.
If accurate, this would make Nakamoto the world’s 16th richest person.
Despite the growing interest in Nakamoto’s identity and holdings, his early decision to remain anonymous and inactive has helped preserve Bitcoin’s decentralized ethos — a principle that continues to define the cryptocurrency to this day.
The United States stock market lost more in value over the April 4 trading day than the entire cryptocurrency market is worth, as fears over US President Donald Trump’s tariffs continue to ramp up.
On April 4, the US stock market lost $3.25 trillion — around $570 billion more than the entire crypto market’s $2.68 trillion valuation at the time of publication.
Nasdaq 100 is now “in a bear market”
Among the Magnificent-7 stocks, Tesla (TSLA) led the losses on the day with a 10.42% drop, followed by Nvidia (NVDA) down 7.36% and Apple (AAPL) falling 7.29%, according to TradingView data.
The significant decline across the board signals that the Nasdaq 100 is now “in a bear market” after falling 6% across the trading day, trading resource account The Kobeissi Letter said in an April 4 X post. This is the largest daily decline since March 16, 2020.
“US stocks have now erased a massive -$11 TRILLION since February 19 with recession odds ABOVE 60%,” it added. The Kobessi Letter said Trump’s April 2 tariff announcement was “historic” and if the tariffs continue, a recession will be “impossible to avoid.”
Even some crypto skeptics have pointed out the contrast between Bitcoin’s performance and the US stock market during the recent period of macro uncertainty.
Stock market commentator Dividend Hero told his 203,200 X followers that he has “hated on Bitcoin in the past, but seeing it not tank while the stock market does is very interesting to me.”
Meanwhile, technical trader Urkel said Bitcoin “doesn’t appear to care one bit about tariff wars and markets tanking.” Bitcoin is trading at $83,749 at the time of publication, down 0.16% over the past seven days, according to CoinMarketCap data.
