According to BlockBeats, on September 30, according to the latest regulatory documents submitted on September 20, MicroStrategy holds a total of 252,220 bitcoins, accounting for 1.2% of the total supply of Bitcoin. Currently, Grayscale GBTC and Mini BTC hold a total of more than 254,000 bitcoins.
But the recent funding leaves MicroStrategy with more than $1 billion in unspent (or at least unannounced) cash, which it will presumably use to buy more Bitcoin, which would add thousands more to its balance sheet and push its holdings far beyond Grayscale’s.
