It's funny that he says it's worthless and has no value but in the same interview says its great for people in Venezuela, Cuba and North Korea. I believe he just made the perfect use case for it without even knowing it. People want a currency that isn't controlled by the government and isn't tied to the whims of central banks who can inflate it and make it worthless at will. And like Gold, it really is limited... it's right there in the code. It's also not easy to generate, so there is no "just print more". Just my 2c. though.
