The financial aspect deserves special mention because the majority of cryptocurrencies operate on blockchain-based systems, so it is inevitable to consider whether a particular state takes a supportive or restrictive approach to regulation. The United Kingdom and the United States have specifically chosen a supportive approach taking into account economic competitiveness considerations<\/o:p><\/p>\n
