On September 7, 2021, El Salvador became the first country in the world to adopt Bitcoin as legal tender. The move, spearheaded by President Nayib Bukele, was bold, controversial, and closely watched by governments, economists, and crypto enthusiasts everywhere. It marked a milestone in Bitcoin's history — the moment a sovereign nation officially embraced cryptocurrency alongside its existing currency.
Bukele's Vision
President Bukele announced the plan at the Bitcoin 2021 conference in Miami, surprising the global audience. His argument was straightforward: roughly 70% of El Salvador's population was unbanked, meaning they lacked access to traditional financial services. Remittances — money sent home by Salvadorans working abroad, primarily in the United States — accounted for over 20% of the country's GDP. These transfers typically flowed through services like Western Union, which charged significant fees.
Bukele saw Bitcoin as a way to solve both problems at once. A digital currency accessible via smartphone could bring financial services to the unbanked while reducing the cost of sending money across borders. The Bitcoin whitepaper itself described a system for peer-to-peer electronic cash that could bypass expensive intermediaries, and Bukele was putting that idea to a national test.
The "Bitcoin Law" passed the Salvadoran legislature on June 9, 2021, with a supermajority vote. It required all businesses to accept Bitcoin as payment if they had the technological means to do so, and it established the U.S. dollar and Bitcoin as the country's two legal currencies.
The Chivo Wallet
To make adoption practical, the government launched the Chivo wallet, a state-backed digital wallet app. Every Salvadoran who downloaded it received $30 worth of Bitcoin as an incentive — a significant sum in a country where the average daily wage for many workers is around $10 to $15.
The Chivo wallet was designed to allow both Bitcoin and dollar transactions, making it easier for merchants and consumers to switch between the two. The government also installed 200 Chivo ATMs across the country and in several U.S. cities with large Salvadoran populations.
The rollout was not without problems. The app experienced technical glitches on launch day, with servers struggling under the load of millions of simultaneous downloads. Some users reported issues with identity verification, and there were cases of fraudulent accounts being created using stolen identity documents. Despite these early stumbles, millions of Salvadorans downloaded the wallet within the first few weeks.
Volcano Mining
One of the more striking elements of Bukele's Bitcoin strategy was the announcement of "volcano mining." El Salvador sits on the Pacific Ring of Fire and has abundant geothermal energy from its volcanoes. Bukele proposed using this clean energy to power Bitcoin mining operations, framing it as an environmentally responsible approach to securing the network.
A pilot geothermal mining facility was established near the Tecapa volcano. While the scale remained modest compared to major mining operations globally, the project attracted significant media attention and demonstrated how renewable energy could be used in Bitcoin mining. Understanding how Bitcoin mining works helps explain why energy sources matter so much to the industry.
Bitcoin Bonds and "Bitcoin City"
Bukele also announced plans for "Bitcoin City," a new urban development at the base of the Conchagua volcano in eastern El Salvador. The city was to be funded in part by "Volcano Bonds" — $1 billion in tokenized bonds that would use half the proceeds for Bitcoin purchases and half for infrastructure. The bond issuance faced multiple delays due to regulatory hurdles and market conditions, and as of early 2025 the full vision has not yet materialized, though the government has continued to purchase Bitcoin for its national treasury.
Results and Criticism
The results of the experiment have been mixed. On the positive side, El Salvador gained enormous international visibility, attracted crypto-focused tourism and investment, and provided financial access to some previously unbanked citizens. The government's Bitcoin purchases, which Bukele regularly announced on social media, appreciated significantly during the 2024 bull market.
Critics, however, have raised serious concerns. The International Monetary Fund repeatedly urged El Salvador to drop Bitcoin as legal tender, citing risks to financial stability. Surveys showed that after the initial curiosity, many Salvadorans stopped using the Chivo wallet, preferring cash or dollar-based transactions. The volatility of Bitcoin's price meant that merchants who held BTC could see their revenue fluctuate wildly — a challenge that has characterized Bitcoin's relationship with traditional fiat systems.
Transparency was another concern. The government's Bitcoin purchases were made from public funds, but details about custody, exact amounts, and realized gains or losses were not always clearly disclosed.
What It Means for Bitcoin
El Salvador's experiment is significant regardless of its ultimate outcome. It demonstrated that a nation-state was willing to bet on Bitcoin as part of its financial infrastructure. It also revealed the practical challenges of mass adoption — from technical infrastructure to user education to price volatility.
For advocates of Bitcoin as electronic cash (as described in the original whitepaper), El Salvador highlighted both the promise and the gap. The vision of fast, cheap, peer-to-peer payments at national scale requires a blockchain that can handle high transaction volumes at low cost. This is precisely the goal of BSV, which has scaled to support enterprise-level throughput while keeping fees fractions of a cent — a capability worth exploring for any nation considering a similar path.

Whether other countries follow El Salvador's lead remains to be seen, but the precedent has been set. The world's first national Bitcoin experiment is still unfolding, and its lessons will shape the conversation around cryptocurrency adoption for years to come.
