New Research Reveals ‘Systemic Risk’ To Bitcoin As Its Price Crashes Under $60,000

Bitcoin and cryptocurrecny prices have rocketed this year, propelling the combined crypto market to over $2.6 trillion.

The bitcoin price has added almost 400% since this time last year, climbing to over $60,000. However, bitcoin has fallen sharply over the last 24 hours, dropping under the closely-watched $60,000 level.

Ahead of bitcoin's price plummet, researchers found the cryptocurrency is still concentrated among a handful of holders, warning this makes "bitcoin susceptible to systemic risk."

"Our results suggest that despite the significant attention that Bitcoin has received over the last few years, the bitcoin ecosystem is still dominated by large and concentrated players, be it large miners, bitcoin holders or exchanges," analysts from the National Bureau of Economic Research wrote.

"This inherent concentration makes bitcoin susceptible to systemic risk and also implies that the majority of the gains from further adoption are likely to fall disproportionately to a small set of participants."

Researchers found the biggest bitcoin holders held around 27% of the total 18.6 million coins in circulation at the end of 2020, with a high degree of concentration among crypto exchanges and so-called miners—those that secure the bitcoin blockchain in return for freshly-minted coins. The top 10% of miners control 90% of the bitcoin mining capacity, with just 0.1%—about 50 miners in all—contributing 50% of this.

"This measurement of concentration most likely is an understatement since we cannot rule out that some of the largest addresses are controlled by the same entity," researchers Igor Makarov and Antoinette Schoar wrote, pointing to many of the early mined bitcoins that are likely all controlled by bitcoin's mysterious creator Satoshi Nakamoto but are spread across some 20,000 different addresses.

The researchers warned that such high levels of concerntration mean the bitcoin network could be susceptible to a so-called 51% attack, where miners could collude to reverse transactions. Such a scenario happened in 2014 when the mining pool Ghash.io briefly controlled 51% of all the bitcoin network's processing power.
