I've just watched this first video.  Nothing new under the sun.

This is privately issued money.  It is a good thing, and it should be more used.  It's based on the trust from the public towards an issuer.  It should be easy to do on internet.  By the way, to some extend, one can consider stock shares to be such a kind of money.

Also, I don't believe hoarding to be a problem.  Especially if the money is divisable enough, as bitcoin is.  But we've discussed about that already in this forum.  Search deflation in topic.

Finally, I find it hard to believe that at the end, he proposes his perpetual coin to be related to the US dollar.  WTF !?

His perpetual coinn obviously has to be bitcoin, or at least a cryptocurrency.
