Price Manipulation in the Bitcoin Ecosystem

What they found
Using leaked transaction data from Mt. Gox, once the dominant Bitcoin exchange, the authors identified two bots that appeared to execute fraudulent trades in 2013. On days when the bots were active, Bitcoin's price rose an average of 4%, versus slightly negative on other days, and the price rise spread to other exchanges. They estimate that this suspicious activity drove the price from around $150 to over $1,000 in two months, and argue that thin markets and unregulated exchanges make crypto uniquely vulnerable to manipulation by a single actor.
What you can use
- One actor with fake volume on one exchange was able to move the global Bitcoin price by hundreds of percent in 2013.
- In a thin, unregulated market, price moves can reflect manipulation rather than demand; treat unexplained rallies with suspicion.
- Volume figures from unregulated exchanges cannot be taken at face value.
Caveats
Relies on leaked, incomplete data from a single exchange in 2013; the market is far deeper now. Correlational evidence of manipulation, not a legal finding.
