Professor Mark Grabowski headlined two major cryptocurrency events at Adelphi University during the Fall 2025 semester, highlighting the institution’s expanding focus on blockchain.

On October 24, 2025, Grabowski led a Cryptocurrency & Blockchain Discussion at Adelphi’s Innovation Center alongside Jeff Rundlet, head of Accounting Strategy at Cryptio. Together, they walked attendees through the fundamentals of Bitcoin, stablecoins, and blockchain, explaining how decentralized networks and digital scarcity create real value. The discussion emphasized that cryptocurrency represents a developing financial infrastructure, not just speculation.

Two weeks later, on November 6, 2025, Grabowski delivered the opening remarks at The Blockchain Summit and Social, co-hosted by Adelphi’s Robert B. Willumstad School of Business and the Long Island Capital Alliance (LICA). He framed the conversation by acknowledging the polarized views surrounding crypto: “When people hear ‘blockchain,’ they usually fall into two camps: some think it’s the future of finance; others think it’s a scam run by teenagers in hoodies. But the truth… is far more interesting.”

He pointed to the data behind blockchain’s resilience: “Over the past 15 years, Bitcoin has been the best-performing financial asset in the world — better than gold, better than the S&P 500, and yes, even better than NVIDIA stock.”

Grabowski also highlighted Adelphi’s early commitment: “Back in 2018, when most people still thought ‘crypto’ was short for ‘cryptic,’ I launched Long Island’s first university course on Bitcoin and Blockchain.”

Throughout his remarks, he emphasized blockchain’s broader significance beyond price charts: “Blockchain isn’t just about technology — it’s about trust, transparency, and financial inclusion.” He noted how quickly the industry is moving, from Bitcoin ETFs to major institutions entering the space, underscoring that what began as a niche experiment is now influencing Wall Street and Washington alike.

He concluded by emphasizing that blockchain’s trajectory is accelerating, with regulatory shifts, institutional adoption, and new technical breakthroughs converging rapidly. Events like the summit, he noted, are essential for helping students, professionals and the broader community understand how these changes will reshape finance, law and technology in the years ahead.

Together, these two back-to-back events demonstrated Adelphi’s growing leadership in blockchain education — and highlighted Grabowski’s continued role in guiding the university’s conversations about the future of digital finance.

Professor Mark Grabowski was quoted in a story published by Cybernews, analyzing Donald Trump’s 2025 executive order on censorship.

The Jan. 27, 2025 article — titled “Trump’s order on censorship: victory for free speech or assault on reality?” — draws on Grabowski’s cyber law expertise to question whether the administration’s push to “end government censorship” might instead undermine democratic discourse.

As Grabowski told Cybernews, the involvement of government in moderating speech “opens the door to a dangerous slippery slope.” He warned that what begins as an effort to curb misinformation could easily expand into suppressing dissenting viewpoints, critical journalism, or unpopular political opinions — a serious blow to free speech and public discourse.

His comments underscore ongoing concerns that new laws and regulations, even those framed as protecting free speech, may carry unintended consequences for media freedom, transparency, and democratic accountability.

Mark Grabowski was quoted in Communications: Journalism Education Today on the issue of book bans.

Book bans have been a hot and controversial topic in the United States lately, with many schools and libraries banning certain books.

"Book bans generally are antithetical to the First Amendment and the fundamental principles of free speech and academic inquiry," said Grabowski, a professor who specializes in free speech, media law and ethics. "I’m concerned by the recent surge of book bans in the United States that appear to be motivated by political considerations. Additionally, I suspect that certain librarians might be covertly engaging in what could be described as "shadow bans." Although these books may not be formally banned, they are deliberately excluded from acquisition and display."

The article, "Banning books another form of censorship," was published in the magazine's Fall 2023 edition.

Mark Grabowski was invited to present his research on The Philippines' regulations of cryptocurrency exchanges at the 2023 Blockchain and Internet of Things Conference (BIOTC 2023).

The fifth annual conference is being held in Osaka, Japan. Grabowski will share his findings he made as a Fulbright Scholar in Philippines, in which he research what other countries could learn from the government's regulation of cryptocurrency exchanges.

​The recent, infamous collapse of Sam Bankman-Fried's popular FTX exchange has created a renewed push for stricter cryptocurrency regulations in the United States and elsewhere. Grabowski teaches cyber law at Adelphi University and is the author of Cryptocurrencies: A Primer on Digital Money.

Mark Grabowski discussed the potential uses and benefits of blockchain technology in real estate transactions in a story published in Newsday.

The story focused on Ranieri Solutions, a startup creating and applying blockchain technology in the real estate and mortgage markets.

Grabowski, who teaches cyber law at Adelphi University and is the author of Cryptocurrencies: A Primer on Digital Money, said that while some could be wary of blockchain technology because of its connection to cryptocurrency, it could be useful in streamlining real estate transactions. 

"It could cut out the middleman, processing fees and time," he said.

Cryptocurrency expert Mark Grabowski was interviewed by multiple news outlets this week about investing in Bitcoin. He offered advice on whether investors should use their Roth IRAs to trade Bitcoin and what the investing outlook was for Bitcoin.

​He told blog CreditDonkey, "While I feel pretty good about Bitcoin's prospects long-term—say a decade from now—it is a very volatile investment. Bitcoin will likely skyrocket at some point in the future but also experience a very big drawdown from that peak. The peaks and bottoms are impossible to predict, and the volatility shakes out most casual investors. So, for the average investor, I wouldn't recommend investing your retirement funds in Bitcoin unless you're willing to put the money in and not look at the price for a few years."

​Grabowski was also discussed the recent cryptocurrency market crash withRussian news outlet Sputnik News. "I don’t think the Google of cryptocurrency exists yet. But eventually the prices will get so low that the upside becomes too large for greed not to take over. Rinse and repeat. The next Bitcoin halving is in April 2024, so I think the market will start heating up again around then or soon after," he said.

Grabowski is an associate professor at Adelphi University in New York, where he teaches a course on cryptocurrency and blockchain. He is author of Cryptocurrencies: A Primer on Digital Money. He also received a 2020 Fulbright Fellowship to research cryptocurrency regulations in Asia and founded his own cryptocurrency project, FreeSpeech.Finance.

Mark Grabowski was quoted in a news story on the history of cryptocurrency. The piece appeared in the blog TechStory.

Grabowski wrote a chapter detailing cryptocurrency's history in his 2019 book, Cryptocurrencies: A Primer on Digital Money.

He also created a short documentary on the topic that's received nearly 30,000 views on YouTube:

With TikTok's ties to China under scrutiny once again as President Biden weighs new rules for foreign apps, Mark Grabowski weighed in on the issue in a recent media interview.

“It is stunning that it’s taken so long for the Biden Administration to conclude TikTok is a national security threat,” he told NTD. “President Trump tried to address this problem, but unfortunately Biden was determined to immediately reverse everything Trump did — whether it made sense or not.”

Grabowski, a professor who specializes in cyber law and ethics, said: "TikTok is Chinese government malware masquerading as a social media app. [It] will go down as the most successful data harvesting of Americans ever done by a foreign adversary."

Iran's Tahlil Bazaar news agency interviewed Mark Grabowski about blockchain, which is an online database technology developed by cryptocurrencies that's now used in many industries.

Grabowski discussed the outlook for blockchain adoption in 2022 along with the benefits and challenges of integrating the technology in the workplace.

"Many big organizations are already utilizing blockchain in some capacity ... I think we’ll continue to see more adoption. COVID-19 has created a number of problems involving health safety, supply chain shortages and scams that blockchain could potentially solve," said Grabowski, who teaches a university course and wrote a book on blockchain.

But, he added that many obstacles exist in widespread blockchain adoption. "First of all, blockchain technology is complex ... Second, blockchain is still a nascent technology ... Finally, cost is a deterrent."

With Major League Baseball teams and players currently at an impasse over a new collective bargaining agreement, mediation is being proposed to help both sides resolve their dispute.

Major League Baseball pointed to Mark Grabowski's research on the high success rate of mediation in pro sports. In 2014, Grabowski published an article in the Harvard Journal of Sports & Entertainment Law that advocated for pro sports teams utilizing mediation to resolve contract disputes.

​The law journal article was cited by MLB.com, the official website of Major League Baseball. It was also mentioned in a Washington Nationals blog and in an article on OnlineGambling.com.

Grabowski, a lawyer and professor, originally wrote the article as a paper for a mediation class he took while attending Georgetown University Law Center.
