Lawdragon has recognized six Cohen & Gresser partners in its 2025 "500 Leading Litigators in America" guide:

This year’s Lawdragon guide highlights "the best litigators the U.S. has to offer" across various categories, following an extensive review of a record number of submissions. The guide focuses on lawyers who have made a significant impact, particularly in recent high-profile matters. The selection process includes in-depth analysis of major litigation and the attorneys consistently sought for key cases.

City A.M. recently featured the insights of Jeffrey Bronheim, head of the Cohen & Gresser’s London office, on the benefits of sharing expertise gained across government and law practice sectors. He writes: “The government should be proud that the people they attract and the training and experience they get are highly prized by other organisations. It is time the UK adopted the US's attitude to the 'revolving door' and welcomed it as an entirely good thing for both the public and private sectors." 

With 3.2 million unique visitors each month, City A.M. is London’s most-read financial and business newspaper, covering the latest economic, political and business news as well as other features.

The Wall Street Journal featured C&G’s Mark Cohen and Christian Everdell recently in an article that described Cohen & Gresser as a go-to law firm for high profile cases.

Blockchain has the potential to transform asset transactions and ownership tracking by reducing counterparty risk, speeding up settlements, and enhancing recordkeeping. As blockchain technology evolves and gains wider acceptance, its use is likely to expand across various asset types, including real and personal property and digital assets. However, unresolved legal issues in the U.S. may create uncertainty in blockchain transactions. This article, written by Douglas J. Pepe, Marvin J. Lowenthal, and Randall W. Bryer for the European Journal of Law Reform, explores key legal challenges and how courts and legislatures are addressing them.

On Sept. 13, 2023, the U.S. Securities and Exchange Commission settled enforcement proceedings against the maker of the Stoner Cats web series arising from its sale of NFTs, reflecting a significant expansion of the SEC’s crypto enforcement efforts into the NFT space. In this C&G Client Alert, Douglas J Pepe and William E Kalema explore the SEC’s position in this instance and the broader implications of its stepped-up enforcement of crypto assets as securities.
In this newsletter for the Cercle des Administrateurs (Club for Board Members), Muriel Goldberg-Darmon discusses the future European rules that will apply to crypto-asset service providers, as well as the regulations that will prevent and sanction market abuse involving crypto-assets. Muriel also analyzes the risk of increasing litigation in the crypto-asset sector.

Alexandra Theobald wrote an article called “Can assets withdrawn from a digital exchange be clawed back in bankruptcy?," that was featured on Blockchain Law Alliance.

In this article for Forbes, Muriel Goldberg-Darmon mentions certain rules that should be included in the final version of the European regulation on Markets in Crypto-asssets (the MiCA Regulation). In particular, Muriel Goldberg-Darmon discusses topics concerning crypto-asset service providers, crypto-assets market abuse, stablecoins, and sustainable digital finance.

A four-count indictment was recently brought by the DOJ and SEC against three individuals, including a former employee of Coinbase, for alleged insider trading of crypto assets. While the DOJ brought the criminal case under the wire fraud and conspiracy statutes, the SEC asserted its claims under the securities laws – marking the first time the SEC has alleged insider trading in violation of securities laws in the crypto context.

  • The SEC action directly raises the question whether the tokens at issue qualify as unregistered securities, with significant implications for whether the platforms that facilitate trading in those tokens are potentially exposed to legal liability as unregistered securities exchanges.
  • While Coinbase is not named in the SEC's complaint as an unregistered securities exchange, the nine tokens mentioned in the complaint were all traded on Coinbase, leaving it unclear what, if any, consequences will result from the SEC’s enforcement action for Coinbase.
  • These are also the first cases to allege “tippee” liability for insider trading in the crypto sphere -- a "tippee" being a person who receives and trades on information obtained by someone else (the "tipper") in violation of the tipper's duty to a third party.
In this client alert, Douglas Pepe, Christian Everdell, and Jesse Greenwald discuss the myriad of issues this case presents for the crypto sphere and analyze the potential implications on crypto exchange if the SEC’s action is successful.

Major League Baseball recently announced a partnership with Sorare, the operator of a fantasy soccer game featuring NFTs, to launch a similar NFT-based baseball game in which fans create a fantasy team of NFTs that represent Major League Players. This venture signals an increased public interest in NFT-based fantasy sports teams, which will likely grow in popularity over the next few years.

  • Although details of the game have yet to be released, Sorare is expected to issue a set number of MLB NFT cards for each player that displays an image of the player in question, with their team and number, much like a physical baseball card. Participants can purchase the cards and then use them to build a team and compete against others.
  • There is some concern among consumers that purchasing digital collectibles, such as NFTs, poses a higher risk than purchasing physical collectibles. If the game collapses, for instance, there is a possibility that purchased NFTs could lose their value.
  • It remains to be seen how this partnership will play out, but given the previous success of Sorare’s fantasy soccer league and the continued public interest in cryptocurrency, it is likely that the MLB game will be a success.
In an article for Blockchain Law Alliance, Marvin J. Lowenthal breaks down why this partnership makes sense and analyzes the potential impacts it could have on NFT purchasing and fantasy sports leagues in the future.

In this C&G client alert, Doug Pepe and Marvin Lowenthal examine the impact of the New York Assembly's bill and highlight the key factors that the responsible departments will use to assess the environmental impact of the mining industry in New York.

New York legislators will soon vote on a bill that would place a two-year moratorium on certain cryptocurrency mining operations that use proof-of-work authentication (POW) methods to validate blockchain transactions in an attempt to maintain compliance with NY’s greenhouse gas emission regulations. While the scope of this bill is relatively limited, how the legislator reacts could provide valuable insight into how receptive various NY departments are to the crypto mining industry as a whole.

  • The bill’s underlying theory is that the continued expansion of crypto mining operations running POW authentication methods to validate blockchain transactions will negatively impact compliance with the Climate Leadership and Community Protection Act, which requires New York to substantially reduce greenhouse gas emissions.
  • Despite some believing this bill will impose an outright ban on all mining, if passed, the bill won’t affect presently operating POW mining operations, instead only prohibiting the issuance of new permits. Mining operations that use alternative energies, such as wind or solar, will also remain unaffected.
  • But the bill could still do serious and lasting damage to NY’s mining industry, as mining operations may be hesitant to invest substantial capital into New York if they fear having their operations shutdown at any time due to changes in the state’s regulatory landscape.
In an article for Blockchain Law Alliance, Marvin J. Lowenthal discusses the reasoning behind and the potential implications of this bill, as well as analyses its potential to become a template for how other states examine their own support for crypto mining.

The UK’s HM Treasury published its response to last year’s consultation on the UK regulatory approach to cryptoassets, stablecoins, and distributed ledger technology (“DLT”) in financial markets on the 4th of April 2022.
  • The Response Document highlights the government’s post-Brexit push to drive transformational growth in the UK’s FinTech space through cryptoassets and DLT and confirms its plans to enact legislation to recognise stablecoins as a valid means of payment by bringing them into the existing regulatory perimeter.
  • The Treasury’s move to make stablecoins a valid means of payment is the first in an array of measures set to be implemented to secure the UK’s status as “the world’s preeminent financial centre” and “a global hub for cryptoasset technology and investment.”
  • The proposed changes should be seen as an effort by the UK to remain relevant in the FinTech space following its exit from the European Union and the damage to its reputation as an attractive business environment that accompanied it.
In this client alert, C&G’s crypto team provides key takeaways from the UK’s HM Treasury response document and offers insight regarding the government’s strategy to support the development of a “world-best crypto ecosystem.”
The Department of Justice (DOJ) has recently signaled a renewed focus on enforcement, and its priorities are being driven by world events.
  • In the past few months, the DOJ has announced new task forces and more resources to combat fraud in connection with COVID-19 relief, criminal activity related to cryptocurrency, and sanctions violations by Russian entities and individuals linked to the Putin regime.
  • These initiatives signal an uptick in criminal enforcement in the coming months, especially in the areas involving fraud, digital assets, sanctions, and money laundering.
This C&G client alert summarizes some of the recently announced initiatives, which shed light on the likely future enforcement priorities.
On March 9, 2022, President Biden issued an executive order on the “responsible development of digital assets.” He directed a “whole government” review of cryptocurrency assets, including directing the Secretary of the Treasury to convene the Financial Stability Oversight Council (“FSOC”).
  • In conjunction with other agencies, the FSOC will study the risks and impact of digital assets and explore the possibility of creating a Central Bank Digital Currency in the United States.
  • The order directs the executive agencies to explore creating a digital version of the U.S. dollar that could be used to facilitate digital transactions while still being controlled by the U.S. Department of the Treasury.
  • President Biden expressed concern about the impact of cryptocurrencies on the integrity of the financial system.
In this C&G client alert, Douglas J Pepe and Alexandra K Theobald review the details of President Biden’s executive order on the “responsible development of digital assets” and offer insight into what we can expect from the government in terms of future guidance and enforcement efforts.
The cryptocurrency industry should brace itself for increased scrutiny from the DOJ and other enforcement agencies. The DOJ recently announced the creation of a National Cryptocurrency Enforcement Team (“NCET”), which will have the authority to tackle investigations and prosecutions of criminal misuses of cryptocurrency. NCET will not only pursue its own cases but will work closely with other federal agencies, subject matter experts, and law enforcement partners throughout the government to support existing and future cases across the country.

  • The announcement further suggests that NCET’s initial mandate will broaden the enforcement focus from criminal actors themselves to those who enable and facilitate illicit activities involving cryptocurrency.
  • Cryptocurrency exchanges should take appropriate steps to work with counsel to avoid becoming the subject of a DOJ investigation or prosecution.
  • The increased scrutiny will also likely extend to all cryptocurrency-focused businesses, NFT platforms, companies that accept cryptocurrency as payment, and even those that merely do business with third parties dealing in cryptocurrency.
  • Given the heightened scrutiny from the DOJ and a constantly evolving regulatory landscape, all companies in the industry should evaluate compliance programs and practices to mitigate risk and exposure.
In this C&G client alert, Christian R Everdell and Barbara K Luse explore the specifics of the NCET mandate, including its anticipated collaboration with the SEC and other federal agencies, and examine what’s on the horizon for cryptocurrency exchanges and other cryptocurrency-focused businesses. The authors identify some key takeaways for companies dealing with cryptocurrency, including cryptocurrency exchanges, crypto funds and financial institutions, and more.
