Who’s the Biggest #bitcoin Whale? Spoiler: It’s Not MicroStrategy

While MicroStrategy holds a staggering 580,000 BTC (worth ~$60.2B), the undisputed largest holder of Bitcoin remains Satoshi Nakamoto, whose early-mined stash still sits untouched at 1.096 million $BTC , now valued at over $112 billion. So if MicroStrategy wants the crown, they’ll need to double down on their bags—literally.

That said, MicroStrategy is the world’s largest corporate Bitcoin holder. Since adopting BTC as its primary treasury reserve asset in August 2020, the company has accumulated its stack at an average cost of $70,023 per BTC, riding it to over $19.1B in unrealized profits. The stock has surged 7x in the past 4 years, proving that sometimes, "conviction beats grind."

Other major corporate holders like Tesla and Japan’s Metaplanet are also contributing to this new wave of institutional accumulation. Curious how these companies are doing?
