Former Operator Of Bitcoin Investment Platform Sentenced For Securities Fraud And Obstruction Of Justice

For Immediate Release
U.S. Attorney's Office, Southern District of New York

Geoffrey S. Berman, the United States Attorney for the Southern District of New York, announced that JON E. MONTROLL, a/k/a “Ukyo,” was sentenced yesterday by U.S. District Judge Richard M. Berman to 14 months in prison.

Manhattan U.S. Attorney Geoffrey S. Berman said:  “Jon Montroll lied to his investors and, after his lies caught the attention of the SEC, lied to them, too.  The sentence he received serves as a reminder that this Office will not overlook those who violate their obligation to be honest with investors and the regulators working to protect them.”

According to the Information, the allegations in the Complaint, and statements made during the proceedings in Manhattan federal court:

JON E. MONTROLL operated two online bitcoin services:  WeExchange Australia, Pty. Ltd. (“WeExchange”) and (“BitFunder”).  WeExchange functioned as a bitcoin depository and currency exchange service.  BitFunder facilitated the purchase and trading of virtual shares of business entities that listed their virtual shares on the BitFunder platform.

Between the launch of Bitfunder, in or about December 2012, and at least in or about July 2013, MONTROLL converted a portion of WeExchange users’ bitcoins to his personal use without the users’ knowledge or consent.  For example, MONTROLL exchanged numerous bitcoins taken from WeExchange into United States dollars, then spent those funds on personal expenses, such as travel and groceries.

Beginning on or about July 18, 2013, MONTROLL promoted a security referred to as “Ukyo.Loan.”  As described by MONTROLL in a public post about Ukyo.Loan, MONTROLL encouraged investors to “think of [Ukyo.Loan] as a sort of round-about investment” in BitFunder and WeExchange and, at the same time, described Ukyo.Loan as “a personal loan” and “for private investment purposes.”  MONTROLL further promised to pay purchasers of Ukyo.Loan daily interest on their investment and promised shares could be “redeemed at face value anytime upon request.”

During the summer of 2013, one or more individuals (the “Hackers”) exploited a weakness in the BitFunder programming code to cause BitFunder to credit the Hackers with profits they did not, in fact, earn (the “Exploit”).  As a result, the Hackers were able to wrongfully withdraw from WeExchange approximately 6,000 bitcoins, with the majority of those coins being wrongfully withdrawn between July 28, 2013, and July 31, 2013.  As a result of the Exploit, BitFunder and WeExchange lacked the bitcoins necessary to cover what MONTROLL owed to users.

Notwithstanding the scope of the Exploit, MONTROLL failed to disclose the Exploit to users of BitFunder and WeExchange, or investors in Ukyo.Loan.  Instead, MONTROLL continued to promote and sell Ukyo.Loan to customers and, on at least one occasion, falsely represented to customers that BitFunder was commercially successful.  As a result of his omissions and misrepresentations, MONTROLL raised approximately 978 bitcoins through Ukyo.Loan after his discovery of the Exploit.

The SEC’s New York Regional Office began an investigation into BitFunder and the Exploit.  During the course of the investigation, MONTROLL provided the SEC with a falsified screenshot purportedly documenting, among other things, the total number of bitcoins available to BitFunder users in the WeExchange Wallet as of October 13, 2013.  Additionally, during sworn investigative testimony on both November 14, 2013, and October 6, 2015, MONTROLL provided materially false and misleading answers to certain questions about, among other things, the timing of MONTROLL’s discovery of the Exploit.

In addition to a prison sentence, Judge Berman ordered MONTROLL, 38, of Saginaw, Texas, to serve three years of supervised release and to pay forfeiture in the amount of $167,480.

Mr. Berman praised the outstanding work of the Federal Bureau of Investigation.  He also thanked the Securities and Exchange Commission, which previously filed civil charges against MONTROLL in a separate action.

The prosecution of this case is being overseen by the Office’s Securities and Commodities Fraud Task Force.  Assistant U.S. Attorney Andrew Thomas is in charge of the case.
