The participation rate of Brazilian women in cryptocurrency trading has surged from 11.34% in 2019 to 29.96% by December 2025, according to the Brazilian Federal Revenue Service. This marks a near tripling over six years, with a peak of 40.95% in January 2024. Despite this increase in participation, the trading volume by female investors remains low at 12.88% in 2025, indicating smaller average transaction sizes compared to male counterparts. In a related development, Brazil introduced the Crypto Asset Declaration System (DeCripto) in 2025, which will require monthly declarations starting July 1, 2026. The system's regulations were shaped with input from female practitioners and civil servants, highlighting the growing involvement of women in the regulatory aspects of the crypto industry.
