Madrid's Growing Bitcoin Scene

Madrid has emerged as one of Europe's most Bitcoin-forward cities. The Spanish capital combines a large, sophisticated financial sector with a growing community of Bitcoin advocates and entrepreneurs. Watch Out Bitcoin serves the Spanish-speaking Bitcoin community and draws international attendees interested in the Iberian Bitcoin ecosystem.

October in Madrid is one of the finest times to visit — the brutal summer heat has broken, the city's parks and terraces are alive with activity, and the cultural calendar is at its richest. The conference runs October 2–4, placing it alongside bitcoin++ Germany in Berlin (October 1–3) — an efficient week for globally mobile Bitcoin attendees.

Retiro Park and Madrid

Madrid is one of Europe's great capital cities. The Prado Museum, Retiro Park (especially beautiful in autumn), the Bernabéu, the tapas and restaurant culture, and the city's legendary nightlife all make it a compelling destination well beyond any conference. Madrid Barajas Airport has excellent connections from across Europe, the Americas, and beyond.
