The Bank for International Settlements (BIS) has released a working paper titled "Crypto trading and Bitcoin prices: evidence from a new database of retail adoption" by Raphael Auer, Giulio Cornelli, Sebastian Doerr, Jon Frost, and Leonardo Gambacorta. The paper presents a novel database on retail use of crypto exchange apps at daily frequency for 95 countries over 2015-22. The authors find that a rising Bitcoin price is followed by the entry of new users, and that retail adoption of cryptocurrencies is driven by a combination of price movements and regulatory changes. The paper contributes to the ongoing debate on the drivers of cryptocurrency adoption and the potential implications for financial stability.
