According to @StockMarketNerd, Nubank’s NU has reached 14 percent of Mexico’s adult population as customers after six years, with Mexico’s ramp running faster than its early Brazil trajectory and NU now serving over 60 percent of Brazil’s adults (source: @StockMarketNerd, Oct 26, 2025). Nubank offers in-app crypto trading in Brazil for BTC and ETH through Nubank Cripto launched in 2022, linking its large user base to crypto market on-ramping (source: Nubank press release, May 2022). Fintech platforms are key fiat on-ramps for retail crypto participation in Latin America, making NU’s accelerating penetration relevant to monitoring access trends for crypto liquidity and adoption (source: Chainalysis, 2023 Geography of Cryptocurrency report). The cited post does not state whether crypto trading is available in Mexico, so no cross-market rollout should be inferred from the penetration data alone (source: @StockMarketNerd, Oct 26, 2025).
