Interesting. As you know I am not really a cryptojunkie I don't really have the patience these days but I have pondered about the future of the platform given how there still needs to be centralised clearing houses to somehow convert fiat currency to virtual stuff. Main problems will always be competition and regulation. Once those to things are the norm then so will all the other financial instruments that go with it.

Like taxing with real money what you make with vitual money

Another pain point for society to wrap it's head around. As technology is evolving faster than society is, we will keep coming up against these pain points where we have no moral guidance, laws or conventions to deal with what technology can do.
