最新报道：According to the latest Chainalysis data, on-chain activity in Sub-Saharan Africa surged to over $205 billion in the twelve months ending June 2025, a 52% increase from the previous year. This growth solidified the region's position as the third-largest cryptocurrency economy globally, currently trailing only the Asia-Pacific and Latin American markets. Researchers point to a particularly sharp surge in March of last year, when a sudden devaluation of the Nigerian currency sparked a rush into cryptocurrency and pushed monthly transaction volume to a staggering $25 billion. Chainalysis data shows that small-value transfers were the cornerstone of this expansion. Over 8% of all on-chain value transferred in Sub-Saharan Africa was for transactions below $10,000. This figure significantly exceeds the global average of 6%, highlighting the deep grassroots adoption of digital assets into everyday financial activities. While retail activity forms the foundation, institutional momentum is also growing, particularly in the region's two largest economies. In Nigeria, which leads by a significant margin with $92.1 billion in receipt value, institutional activity is becoming increasingly visible beneath the surface. The report notes that high-value stablecoin transfers facilitate trade flows in sectors such as energy, as well as commercial payments between Africa, the Middle East, and Asia, establishing cryptocurrencies as a vital settlement rail underserved by traditional finance. South Africa, the region's second-largest market, demonstrates a model of institutional maturity driven by regulatory clarity. The country boasts hundreds of licensed virtual asset service providers, fostering a formal ecosystem that attracts institutional participants. Notably, major financial institutions such as Absa Bank are currently in the advanced stages of developing cryptocurrency custody and stablecoin products, marking a critical shift from theoretical exploration to active product development for sophisticated clients. The data also highlights how token preferences reflect local realities. In Nigeria and South Africa, Bitcoin (BTC) still plays a significant role compared to other markets. It accounts for 89% of fiat currency purchases in Nigeria and 74% in South Africa, significantly higher than the 51% of US dollar transactions. Beyond BTC, stablecoin adoption, particularly USDT, has been more pronounced than in Western markets, accounting for 7% of purchases in Nigeria. This reflects their critical role as digital dollar alternatives for savings and informal foreign exchange acquisition in economies facing significant discrepancies between official and black market exchange rates.
