The presumptive Republican U.S. presidential nominee will be speaking at the upcoming Bitcoin conference in Nashville, Tennessee, later this month, the conference organizer announced Wednesday. Earlier in the day, speculation of a Trump appearance increased as speakers told CoinDesk their slot was reassigned to make room for what an email described as “a very special guest.” Former President Trump will be speaking at 2 p.m. CT for 30 minutes on the last day of the conference, which runs from July 25-27, a spokesman for the conference told CoinDesk.
