India and the United States have emerged as the leading countries in cryptocurrency adoption for 2025, according to Chainalysis' Geography of Cryptocurrency Report. India ranks first across all sub-categories, while the U.S. follows, bolstered by institutional interest and the approval of spot bitcoin ETFs. Pakistan, Vietnam, and Brazil round out the top five. The Asia-Pacific region is the fastest-growing, with a 69% increase in on-chain transaction volume, driven by India, Pakistan, and Vietnam. Latin America and Sub-Saharan Africa also show significant growth. Stablecoins such as USDT and USDC are pivotal in global adoption, with Circle's EURC and PayPal's PYUSD experiencing notable growth. Bitcoin remains the primary entry point for fiat on-ramps, with the U.S. leading in fiat inflows. The report notes widespread adoption across various income levels, though lower-income countries face greater vulnerability to economic shocks.
