This question is what lead me right back to Bitcoin. Bitcoin can do anything enabled through the power of layered technology. The same approach we use to build the entire internet. I still think its healthy to ask this question frequently because it isn't impossible that something better comes along but you really have to ask yourself since the start of money and value itself, has anything else better come along? What are the chances of something better than Bitcoin being invented considering all that time spent getting to this point? I personally am not willing to risk being on the other side of that question.
