"This report surveys the legal and policy landscape surrounding cryptocurrencies around the world. While not dissimilar in form to the 2014 Law Library of Congress report on the same subject, which covered forty foreign jurisdictions and the European Union, this report is significantly more comprehensive, covering 130 countries as well as some regional organizations that have issued laws or policies on the subject. This expansive growth is primarily attributable to the fact that over the past four years cryptocurrencies have become ubiquitous, prompting more national and regional authorities to grapple with their regulation. The resulting availability of a broader set of information regarding how various jurisdictions are handling the fast-growing cryptocurrency market makes it possible to identify emerging patterns, some of which are described below. The country surveys are also organized regionally to allow for region-specific comparisons."
