Brazil is rapidly emerging as a key player in the global cryptocurrency market, with Nubank, backed by Warren Buffett, expanding its offerings to include four new altcoins—Cardano, Near Protocol, Cosmos, and Algorand—bringing its total to 20 digital assets. This growth reflects a broader trend of increasing digital currency adoption in Brazil, where stablecoins account for 90% of transactions, and the government is exploring legislation to allow salary payments in Bitcoin. Nubank's revenues have surged from $245 million in 2021 to nearly $3 billion in 2024, underscoring the rising demand for crypto services in the region.
