The question of benefits and costs of cryptocurrencies is interesting, so I read the paper. Unfortunately, poor readability, strange assumptions such as the dollar value of social benefits of cryptocurrencies (confusing with dollar value of mining) and strange desiderata such as dollar value of mining being higher than dollar value of costs. Clear bias towards regulating and policy targeting of cryptocurrencies. There is no mention of the fact that pollution is produced by power plants and directly controllable by their owners, not cryptocurrency miners. No mention of the fact cryptocurrencies are less than 1% of total world electric energy consumption. A proper analysis of costs/benefits would put cryptocurrencies' externalities in perspective to other comparable and bigger consumers (cryptocurrencies are a very small part). This disproportional targeting of cryptocurrencies as the most important climate destroyer that we see in the news seems to be unwarranted. Also, somehow the fact that pollution is generated by power plants, not consumers, is not so hot topic.
