Summary
An academic working paper from the University of Chicago studying Bitcoin’s adoption in El Salvador following its legal tender mandate in September 2021. Uses representative national survey data to document usage patterns and estimate the fixed cost of adopting new payment technology. Finds that despite major government incentives, Bitcoin adoption as an everyday medium of exchange was low and concentrated among already-advantaged populations.
Key Points
- El Salvador = the only natural experiment in the world on Bitcoin as legal tender.
- Government provided “big push”: Chivo Wallet, $30 per-user incentive, mandatory merchant acceptance.
- Despite this, everyday Bitcoin transaction use was low.
- Adoption concentrated among: banked, educated, young, male populations — the opposite of who financial inclusion advocates target.
- Coordination failure: people don’t adopt Bitcoin because merchants don’t accept it; merchants don’t accept it because customers don’t use it. Government mandate didn’t break this equilibrium.
- Paper estimates the fixed cost of adopting new payment technology and the strategic complementarities (network effects) that make coordination failures sticky.
- Bitcoin does not meet the medium-of-exchange function definition per classical economics (Jevons’ medium of exchange criterion).
Newsletter Angles
- This is the most rigorous academic treatment of “can Bitcoin actually be currency?” The answer from this data is essentially no — at least not without coercion, and coercion doesn’t work well either.
- The demographic finding (adoption by already-banked population) is a devastating critique of financial inclusion arguments for crypto.
- The coordination failure framing is analytically powerful: Bitcoin’s adoption problem isn’t technical, it’s game-theoretic. You need critical mass, and mandates don’t create genuine critical mass.
Entities Mentioned
- El Salvador — the country studied
- Nayib Bukele — the president who enacted the policy (implied)
Concepts Mentioned
- El Salvador Bitcoin Experiment — this paper is a primary source for that concept
- Strategic Bitcoin Reserve — if Bitcoin can’t function as currency in El Salvador, the reserve case rests on “digital gold” not “digital cash”
Quotes
“Despite the government’s ‘big push’ and a large fraction of people downloading Chivo Wallet, usage of bitcoin for everyday transactions is low and is concentrated among the banked, educated, young, and male population.”
Notes
This is a working paper (2022) — pre-peer-review at time of writing, but from a credible institution with strong methodology. The coordination failure analysis is the most analytically interesting contribution. The data predates the 2025 removal of legal tender status, which confirmed the paper’s core pessimistic findings. This is the strongest single academic source on Bitcoin-as-currency failure.
