That's not what I'm saying at all. Bitcoin proved to the world that a cryptocurrency can work, I just think we can do better, and clearly the world agrees. There's a lot more people talking about bitcoin than using it. If a cryptocurrency is to gain wide adoption, it must actually be a currency, and bitcoin by its nature is not, it is a commodity. The reason bitcoin is not being adopted faster is not because very few people know about it, but because a lot of people are aware of this fact. I think that there can be a global cryptocurrency, but it's impossible for bitcoin to be it- as is. Since bitcoin can't really be changed much as released, any improvement would be a new coin, and like I said before, I think we can do better.
