Michael Saylor, executive chairman of MicroStrategy, stirred new speculation this week after publishing a short but familiar message: “Stay humble. Stack sats.” In the world of Bitcoin, those words rarely come without intent especially when posted by the largest public holder of BTC on the planet.
MicroStrategy currently holds 601,550 BTC, following its latest acquisition of 4,225 coins in July. The company spent approximately $472.5 million on the most recent buy, bringing its total Bitcoin portfolio to a market value nearing $71 billion.
Strategic timing
The post comes at a moment of consolidation in the crypto market, with Bitcoin facing short-term headwinds but strong long-term fundamentals. Saylor’s comment, while brief, fits his usual pattern: accumulate quietly, signal publicly, and let the market do the rest.
Whale activity has also surged, with wallets holding more than $1 million in BTC rising steadily. At the same time, institutional ETF inflows have passed $3 billion in a single week another sign of deep-pocket interest.
One message, one strategy
From the beginning, Saylor has described Bitcoin as “economic gravity” and “the most efficient store of value ever created.” His strategy remains unchanged: buy in size, hold with conviction, and communicate through simplicity.
This week’s message may have been only four words. But for those watching closely, it said enough.
