SEC Obtains Final Judgments Against Attorney and Law Firm Business Manager Charged with IIIegal Sales of Ubi Blockchain Internet Stock

Litigation Release No. 24190 / July 9, 2018

Securities and Exchange Commission v. T.J. Jesky, Esq. and Mark F. DeStefano, Civil Action No. 18-CV-05980 (S.D.N.Y. Filed July 2, 2018)

On July 2, 2018, the Securities and Exchange Commission charged two men alleged to have profited from illegal sales of stock of a company claiming to have a blockchain-related business. Earlier today, the district court approved a settlement with both men.

According to the SEC's complaint, attorney T.J. Jesky and his law firm's business affairs manager, Mark F. DeStefano, made approximately $1.4 million by selling shares in UBI Blockchain Internet, Ltd. over a 10-day period from Dec. 26, 2017 to Jan. 5, 2018. The sales stopped when the SEC temporarily suspended trading in UBI Blockchain stock earlier this year due to concerns about the accuracy of assertions in its SEC filings and unusual and unexplained market activity.

The SEC's complaint alleged that Jesky and DeStefano, both residents of Nevada, received 72,000 restricted shares of UBI Blockchain stock in October 2017 and were permitted to sell the shares at a fixed price of $3.70 per share under the registration statement. Instead, the complaint alleges that Jesky and DeStefano unlawfully sold the shares at much higher market prices - ranging from $21.12 to $48.40 - when UBI Blockchain's stock experienced an unusual price spike.

The SEC's Office of Investor Education and Advocacy has issued an Investor Bulletin on initial coin offerings and a mock ICO website to educate investors. Additional information about ICOs is available on and

The SEC's complaint, filed in federal court in New York, charged Jesky and DeStefano with violating the registration provisions of the federal securities laws. Without admitting or denying the allegations in the SEC's complaint, Jesky and DeStefano agreed to return approximately $1.4 million of allegedly ill-gotten gains, pay $188,682 in civil penalties and be subject to permanent injunctions.

The SEC's investigation, which is ongoing, is being coordinated by the Microcap Fraud Task Force and the Cyber Unit and is being conducted by Michael D. Paley, Kevin P. McGrath, Tracy E. Sivitz, John P. Lucas, and Ricky Tong. The matter is being supervised by Lara S. Mehraban and Robert A. Cohen. The SEC appreciates the assistance of the Financial Industry Regulatory Authority, the Mexican ComisiĆ³n Nacional Bancaria y de Valores, and the Panamanian Superintendencia del Mercado de Valores.
