When it comes to buying Bitcoin, nobody does it quite like Michael Saylor.
This month, MicroStrategy (MSTR) announced it picked up 15,355 BTC for around $1.42 billion, at an average price of 92,737 USDT each.
And the crazy part?
The market barely noticed.

As of April 27, 2025, MicroStrategy now holds 553,555 Bitcoin, acquired for about $37.90 billion total. Their average buy price sits around 68.4k, and they’re up 13.7% year-to-date.

So how did Saylor and his team pull off such a massive buy without causing a giant green candle or Twitter explosion?

Let’s break it down.

1. Deep OTC Block Trading

Saylor never just logs onto Coinbase or Binance to hit the “Buy” button.
Instead, he goes through OTC desks — deep liquidity brokers like Coinbase Prime, Galaxy Digital, Kraken OTC, and trading syndicates like Jump and Cumberland.

OTC (Over-the-Counter) means the trades happen privately, not on public exchanges.
These desks are like “deal architects” — they quietly source liquidity without touching the order book. No slippage. No panic.

2. Fragmented Sourcing: Little by Little

Instead of finding one big seller, the OTC desks pieced the 15,355 BTC together from hundreds of smaller sellers:

• Miners cashing out.
  
• Whales trimming positions.
  
• Custody desks rebalancing.
  
• Bankruptcies like FTX/Celsius slowly offloading.
  

Each transaction was small enough to not ring alarms.
It’s like Saylor bought a little bit from everybody and stitched it together behind the scenes.

3. Time-Weighted Algorithms

They didn’t just buy it all in one day.

The buys were spread over days and weeks, using sneaky execution strategies:

• TWAP (Time-Weighted Average Price): Buying a little bit every hour.
  
• VWAP (Volume-Weighted Average Price): Matching buys with the market flow.
  

They even randomized the size and timing of buys to blend in.
If the market dipped suddenly, they sniped extra BTC during the chaos — all automated.

4. Custody Without the Spike

Where did all this Bitcoin go?

Straight into secured custody with giants like Fidelity, Coinbase Custody, and Anchorage.

Here’s the trick:
OTC desks first hold the coins off-chain, bundling them over time.
Only when everything’s ready do they move the Bitcoin into MicroStrategy’s cold storage — usually in batch transactions.
That’s why there’s no huge on-chain movement you can see live.

5. Perfect Timing: Dead Zone Shopping

Saylor’s team also picked their timing perfectly:

• Weekends when volume is low.
  
• Mini crashes when people panic sell.
  
• Holidays when traders are distracted.
  

Less competition = quieter fills = cheaper Bitcoin.

Final Thoughts

Michael Saylor’s BTC buying sprees aren’t just lucky guesses.
They’re surgical operations, designed to maximize stealth and minimize impact.
