The legal trial related to defunct Israeli exchange Coin.mx has slowed down after the prosecution produced a new witness. Coin.mx is under suspicion for operating under a fake image while illegally accruing mlns of dollars in Bitcoin.

Parties are in court on matters relating to the exchange’s illegal activities and those of its operator and owner.

In a lengthy investigation, now two years after the exchange closed down, authorities are still probing those connected either to Coin.mx, its operator Anthony Murgio and its alleged owner, Gery Shalon.

Among them are two men, Yuri Lebedev and Trevon Gross. Lebedev is thought to be Coin.mx’s “architect,” Reuters reports, while Gross is under suspicion due to tax issues from a now-defunct credit union.

Their trial is on hold after the prosecution called a new witness against Gross, Philip Burgess, yet the case judge stated: "It is my conclusion that we will proceed tomorrow and the government may not call Mr. Burgess.”

Coin.mx is under suspicion for operating under a fake image while illegally accruing mlns of dollars in Bitcoin. Its operators are suspected of being involved in a data hack on global consultancy firm JPMorgan Chase, but the charges do not involve Lebedev or Gross.
