🇦🇷 Local energy and influence
Many visitors fell in love with Buenos Aires for its spring atmosphere and lively streets, yerba mate culture, asado and steak, ice cream, soccer energy, street art, and surrounding nature. Some stay far beyond Devconnect.
Buenos Aires was the perfect location to host the first Ethereum World Expo. Argentina has one of the most active cryptocurrency markets in the world, with around 20% owning cryptocurrencies and using it for savings, inflation hedging, access to credit, and stability. Across the city, many vendors accept cryptocurrencies for payment, and this familiarity made Devconnect feel like they were in the right place at the right time. Devconnect itself was also formed with contributions from the local and regional Ethereum community.
