The U.S.-listed company signed a 10-year contract covering 20 megawatts with a California cloud operator. Including extensions, the agreement is expected to generate more than $1.2 billion in revenue over as long as 20 years. Hyperscale Data's Bitcoin holdings fell 79%, from about 1,006 BTC on July 30 to 215 BTC in late August, while its stock dropped 17% in the latest trading session.
