Japan's largest brokerage Nomura Holdings is considering a sale of its crypto subsidiary Laser Digital Holdings AG, with private markets firm Marex Group evaluating the deal, according to people familiar with the matter. Nomura has not made a final decision and may ultimately sell to another party or retain the business. Spokespeople for both Nomura and Marex declined to comment. Zurich-based Laser Digital posted a loss last year amid sharp crypto market volatility, dragging Nomura's European division into an overall loss.
