Why didn’t MicroStrategy’s $423M investment move Bitcoin’s price?
Although the range is wide, this volume can be narrowed down to 4, maybe 5 exchanges like – Coinbase, Bitstamp, Kraken, Bitfinex, Gemini, etc. These centralized exchanges have about 90% of all the trading volume. So, if MicroStrategy or other institutions were to buy huge sums of Bitcoin, they would have to partner with any and all these exchanges and OTC desks.
Considering MicroStrategy’s sizeable buy, and with the assumption of them partnering with multiple exchanges, the question about the market impact still persists.
To acquire 16,796 BTC (disclosed 9/14/20), we traded continuously 74 hours, executing 88,617 trades ~0.19 BTC each 3 seconds. ~$39,414 in BTC per minute, but at all times we were ready to purchase $30-50 million in a few seconds if we got lucky with a 1-2% downward spike.

There are two ways to look at MicroStrategy’s purchase,
- Assuming that MicroStrategy was limited to soak up 10% of the buy-side liquidity. This would mean MicroStrategy bought $1.24 billion [10% * $1.24 billion] worth of Bitcoin per day.
- But from the tweets, we can deduce that only $56 million in cash was used to buy Bitcoin per day in September.
Speaking with Anthony Pompliano, Michael Saylor, the CEO of MicroStrategy had said,
“I can’t give you exact blow-by-blow details because I’ve got security issues and the world is watching… “
He also spoke of “auditioning institutional-grade exchanges and custodians,” further confirming that the purchase indeed took place on multiple platforms. Another dead giveaway is that a single exchange cannot handle the liquidity of around $400 million, without moving the price.
However, what confirms that MicroStrategy did not employ $1.24 billion per day is Michael Saylor explaining about the buy in the podcast.
“If you’re going to buy that much bitcoin, you’re going to buy it in thousands, or tens of thousands plus small transactions day and night, minute by minute… you’ve got to have the right team and the technology and be very patient.”
Additionally, he mentioned,
“… no one that really wanted to buy a lot of bitcoin would be so silly as to spike the price… we bought 425 million dollars worth of it and we never ran the price, not a dollar.”
Clearly, Saylor and his team wanted to do this quietly and not move the price. In fact, he also mentioned that he would be lucky if the price dropped by 1-2% so they could accumulate more Bitcoin.
Hence, we can conclude that MicroStrategy had a goal, even before they decided to buy Bitcoin, and that was to not move the price and be unseen.
Square root law of market impact
This law calculates the market impact of buying huge sums of stocks/assets. Any market impact model created is derived from the following formula,
The Q in the formula represents the total number of shares, in this, total Bitcoins purchased, V is the average daily volume and the σ is the daily volatility. So, a rough calculation from the formula shows that the impact is 0.56%.
Theoretically, this is an extremely small impact. Even considering all the factors in play, it wouldn’t be more than 5%. Even if it was a 5% impact, the Bitcoin market is volatile enough for it to go unnoticed. Additionally, considering the dates of purchase haven’t been provided by MicroStrategy, it can be hard to actually verify the impact of the buy.
So, to answer the question, yes, MicroStrategy’s Bitcoin buying did impact the price, but it went unnoticed since nobody had an idea about the buy. Furthermore, an important takeaway from this is that the Bitcoins are being used as a reserve asset. This would mean that shareholders would be exposed to Bitcoin. Freely speaking, this is a de-facto ETF.
Moreover, in the podcast, Saylor also mentioned that there are 35,000 publicly-traded companies carrying a total of $5 trillion in spare cash getting negative real returns due to the pandemic. Twitter’s CashApp alone has about $10 billion in spare cash just lying around. So, even if 1%-2% of this capital [$5 trillion] flows into Bitcoin, this would easily push its market cap to $2 trillion and beyond.
With necessary institutional portals like Bakkt and the CME functioning smoothly, it is only a matter of time before companies realize how helpful Bitcoin can be as a hedge against inflation. This phase would be an interesting one to keep an eye out for.
