Mars Finance News: Dogwifhat announced the cancellation of its originally planned advertising at the Las Vegas Sphere venue and will refund nearly $700,000 in cryptocurrency previously raised. The project had planned to showcase its token image in the first quarter of 2025 but was denied by the venue, which stated that no collaboration had been reached and there were no future display plans. The organizer, Edward, said that the related statement led to the withdrawal of partner brands, forcing the advertising plan to be terminated, with refunds to be initiated this week.
