This latest acquisition comes as the crypto ecosystem is gearing up for the Bitcoin halving, set to occur in April 2024, and potential spot bitcoin exchange-traded fund (ETF) filings in the United States. 

MicroStrategy made its purchase before the Bitcoin halving as “they are all about maxing out their profit potential,” head of growth at crypto index platform Phuture Charles Storry told Unchained.

Per CoinGecko data, the software intelligence firm holds the most BTC in its treasury among publicly traded companies by a wide margin. MicroStrategy has more BTC than the next 20 companies combined, which add up to 80,623 BTC on the balance sheets of firms like Marathon Digital Holdings, Galaxy Digital Holdings, Tesla and Coinbase.
