A bunch of cryptobros who don’t really have an interest in playing video games started to think “what if everything in a game was a cryptocurrency, and what if instead of playing for fun, you invested in the game to earn more money?”
Seriously, “play-to-earn” is the thing they want to make happen. They took all those boring trends that make shitty microtransaction-fests feel like a job, and they saw a future where stuff like this would actually be your job.
