币界网报道：Cuba is experiencing a quiet but growing Bitcoin revolution as citizens increasingly turn to cryptocurrencies to circumvent economic sanctions and hyperinflation. With limited access to traditional banking and the U.S. dollar restricted due to embargoes, Cubans are adopting peer-to-peer Bitcoin trading via platforms like Telegram and local meetups. Independent tech communities, such as the Havana-based "CriptoCuba," are educating locals on crypto wallets and decentralized finance. Despite slow internet speeds and government skepticism, Bitcoin remittances from abroad now account for a significant portion of family incomes, bypassing costly intermediaries. The Cuban government, while wary of decentralized currencies, has cautiously allowed crypto usage amid its worst economic crisis in decades. Some state-run enterprises even accept Bitcoin for services, though regulatory clarity remains absent. Meanwhile, underground "crypto cafés" offer offline trading tutorials, reflecting grassroots demand for financial sovereignty. This organic movement highlights how geopolitical constraints are accelerating crypto adoption in unexpected regions.
