I think bitcoin's value lies both in its ability to move wealth effortlessly across borders as well as being the digital equivalent of the US Dollar, in that the other crypto-currencies are traded against btc, just like commodities are traded in dollars.
But what if it becomes like a new "consumer prices index"?
What if Bitcoin becomes the new Zero?
Numbers existed before Zero did.
I'm not sure I understand what you mean with New Zero, but if you're asking if I think bitcoin will one day be worth nothing, then yeah, anything can become worthless.
I just don't worry too much about bitcoin going to zero because a. I don't own a lot of bitcoins and b. If it goes to zero some other crypto-currency will have replaced it due to being more useful.
Personally, I see a lot of merit in the argument that we are in the beginning of the process of moving from fiat currencies to crypto-currencies, just as humans moved from precious metal currencies to paper.
Doesn't really matter what happens to bitcoin in the long run, crypto-currency is here to stay, IMHO.
