Legality of Cryptocurrency Around the World
The Library of Congress has done an excellent job of providing a current snapshot of the legal status of cryptocurrency around the world. For a full report in PDF, go to this site: https://www.loc.gov/law/help/cryptocurrency/cryptocurrency-world-survey.pdf
Some countries like Pakistan are already considering more positive treatment of crypto, but for now the list of countries where there is an absolute ban on cryptocurrency can be found here: Countries with ban on cryptocurrency
A review of the regulatory framework for cryptocurrencies (applicability of tax laws, anti-money laundering etc.) can be found here: Regulatory Framework
Laws are constantly changing. If you would like me to provide more in-depth legal research relating to any country and its treatment of cryptocurrency, please let me know in the comments below.
