Personally, I don't see cryptocurrency ever going back to $0, the technology is better than existing models of centralized banking and middle men. Unless something comes along that disrupts the disruptor, I think it's here to stay for the forseeable future.
I agree, but not enough to put more than a small slice of my net worth in at this point. Fortunately, if it doesn't go to zero, it'll probably 100x or 1000x again, so I'll be fine with just a small slice of my net worth :)
