If you're starting a pop group in Japan, where giant rosters and virtual superstars are par for the course, how do you stand out? By tying yourself to something trendy -- and in 2018, that means cryptocurrency. Meet Kasotsuka Shojo (Virtual Currency Girls), a J-pop group where each of the eight girls represents one of the larger digital monetary formats. Yes, you're supposed to cheer for bitcoin or swoon over ethereum (what, no litecoin?). The group played its first concert on January 12th, and naturally you had to pay in cryptocurrency to be one of the few members of the general public to get in.
