The digital bank Nubank, backed by billionaire investor Warren Buffett, has expanded its cryptocurrency offering by introducing four new altcoins. From March 25, the over 100 million Brazilian customers of the platform can now buy and trade Cardano (ADA), Near Protocol (NEAR), Cosmos (ATOM), and Algorand (ALGO). This expansion brings the total number of digital assets available on Nubank Cripto to 20, further consolidating the institution’s presence in the digital currency sector.

The adoption of four new cryptocurrencies represents a significant milestone in the growth path of Nubank in the crypto sector. The bank had already integrated into its portfolio Bitcoin (BTC), Ethereum (ETH), Solana (SOL), XRP and the stablecoin USDC.

The introduction of ADA, NEAR, ATOM, and ALGO adds an overall market value of 34.6 billion dollars to the institution’s offering. This decision follows a series of strategic moves by the bank to consolidate its position in the cryptocurrency sector, initiated with its entry into the market in 2022.
The expansion not only concerns the offering of digital assets but is also reflected in the financial growth of the bank. According to data reported by Statista, Nubank’s revenues increased from 245 million dollars in 2021 to almost 3 billion dollars in 2024, demonstrating the strong increase in its user base and the demand for crypto services.
The Role of Warren Buffett and the Expansion of Digital Finance
One of the most relevant aspects of Nubank’s success lies in the continuous support of Warren Buffett through Berkshire Hathaway. The investment company initially invested 500 million dollars in the fintech company in 2021, then increased its stake with an additional billion dollars. In 2024, Berkshire Hathaway increased its investment, moving from a 0.1% to 0.4% stake in the bank. This trust from one of the most influential investors in the world has helped to strengthen Nubank’s credibility and attractiveness in the financial market.

Nubank and the crypto sector in Brazil
“`
The expansion of Nubank’s crypto platform fits into a context of growing adoption of digital currencies in Brazil, the largest market in Latin America with an estimated GDP of 5.4 trillion dollars.
The country has recorded remarkable growth in the crypto sector, with stablecoin representing 90% of digital transactions. In January 2025, Binance became the first exchange to obtain a broker-dealer license in Brazil, while other fintech companies like Revolut have also expanded their presence in the country.
In 2024, Brazil led the region with a cryptocurrency trading volume of 6 billion dollars. Additionally, the government is considering a legislative proposal to allow the payment of salaries in Bitcoin, a move that could significantly transform the local financial landscape.
Growth of crypto adoption in Latin America
The adoption of cryptocurrencies in Latin America continues to grow rapidly. According to the Crypto Landscape in Latin America report by Bitso, in 2024 the number of users of the exchange platform in this region increased by 12%.
Investor behaviors are also evolving, with 38% of users owning at least three different cryptocurrencies, indicating greater sophistication in investment strategies. This change is particularly evident in Argentina, where the economic crisis and inflation exceeding 100% have led many citizens to view stablecoins as a safe haven.
In Argentina, the reduction of currency controls has further encouraged the adoption of cryptocurrencies, increasing Bitso’s user base by 11%, reaching 1.6 million users. Brazil has also seen steady growth, with a 6% increase in the crypto base, reaching 1.9 million users. Stablecoins represent 26% of purchases in the country, a figure that reflects concerns about the devaluation of the real and the growing interest in decentralized finance (DeFi).
A future increasingly digital
The entry of four new cryptocurrencies into Nubank’s portfolio strengthens its leading position in the digital financial sector of Latin America. With a growing adoption of digital currencies by institutional and retail investors, Brazil seems destined to consolidate itself as one of the most relevant crypto markets globally.
The cryptocurrency sector continues to evolve rapidly, with regulation and investor trust playing a key role in defining its future. The progressive integration of digital assets by banks and fintech is helping to normalize the use of cryptocurrencies, making them an increasingly concrete reality for millions of people.
