August flipped the script. Bitcoin fell 4.98%, yet the total crypto market cap held firm at $3.87 trillion, according to CoinMarketCap. The CMC Fear & Greed Index slid from 68 to 47. Bitcoin traded in a tight range, $109K to $124K. While BTC cooled off, altcoins quietly stole the spotlight. Public Companies Keep Buying Corporate players stayed aggressive. This week alone, public firms snapped up 3,081 BTC. Digital asset treasuries (DATs) now control 3.5% of Bitcoin’s supply. Leading the charge? MicroStrategy. The software giant added 3,081 BTC this week at an average price of $115,829. Total spend: roughly $357 million. MicroStrategy now owns 632,457 BTC, more than 3% of Bitcoin’s total supply. No other public company comes close. Japanese firm Metaplanet joined the action. On August 24, it bought 103 BTC for $11.7 million. That purchase brings Metaplanet’s total to 18,991 BTC. It remains one of Asia’s most aggressive corporate Bitcoin buyers. Another mover? DeFi Development Corp (DDC). The company picked up 320 BTC this week, lifting its total to 1,008 BTC. That makes DDC the 42nd largest corporate holder. Why This Institutional Accumulation Matters Public companies now treat Bitcoin as a strategic reserve asset. MicroStrategy dominates with over 632K BTC. Metaplanet keeps adding despite market volatility. DDC joins the top 50 holders. Institutional accumulation shows confidence even as prices dip.
