Alright, straight up. DDC, or Digital Currency Group, is a major player in the Bitcoin and crypto space. They invest in and build companies focused on digital assets, owning stakes in firms like Grayscale and Foundry, a big Bitcoin mining operation. That's their business core: backing Bitcoin infrastructure.

As for annual turnover, exact numbers ain't public for the last 3 years. They're a private outfit, so no mandatory filings to dig into. Best guess from industry reports is revenue in the hundreds of millions annually, driven by mining and investment gains, especially during Bitcoin bull runs. If you want deeper stats, hit up their site or filings if you can find 'em. What’s your next question?
