Cryptocurrency exchange BitMEX, whose founders were pardoned by U.S. President Donald Trump last year, said on Thursday it will shut down its operations in September and urged customers to withdraw their assets.

BitMEX did not give a reason for the closure but said in a statement on its website that the decision followed a “strategic review of the business and the broader crypto industry” by its owner, Seychelles-registered HDR Global Trading.

BitMEX called on users to close their open positions and withdraw their funds before the closure on September 23.

The closure comes as crypto prices are faltering. Bitcoin has surrendered most of its gains from last year after a rally fueled by Trump’s election to a second term fizzled out.
