GDP-weighted shadow economy as percentage of GDP: Mean 22.67%
https://www.cia.gov/library/publications/the-world-factbook/geos/xx.html
World GDP: $120.2 trillion (2016 est.)
If Bitcoin's market cap reaches the entirety of the global shadow economy (excluding all of its value from non-shadow uses), Bitcoin's market cap would therefore be $27.2 trillion. Potential for its current $0.136 trillion cap to increase 200x.
