The post is written in a great attracting manner, that makes you keep reading. However, it's more unrealistic that accurate. Yeah, this guy predicted $10k, but his $100k for 2019 is probably a seriously overrated prediction.
Almost no governments in 7 years? That's also extremely weird. The govs are not only responsible for taxes and economic stability. There are other political, organizational and legal issues they will keep solving even if mass adoption really happens.
Apart from that, this person suggests that deflationary economics in bad in the long run, while Japan has been doing pretty good with it, and the topic is not researched enough.
