There have been plenty of discussions from time to time on the price speculation of Bitcoin. Where do you guys see the price of one Bitcoin in the years to come? Most importantly, why? How would Bitcoin work? Bitcoin can not exist independently without any other currency, because then where do you derive its value? Imagine Bitcoin though is adopted worldwide, as a popular secondary means of processing transactions. What should the value be of a Bitcoin if literally every person who owned a bank account and debit and credit cards also used Bitcoin wallets and bitcoins daily
Bitcoin derives its value form being an Internet currency, fast and reliable against fiat transactions, slow and troublesome. In this fashion, it can exist without any other currency alongside. In my view, it would work even better in the latter case.
Also, as previous posters have noted, much of its value comes from speculation, why then it can't be said that it derives its value from speculation as well? Maybe, it's not the best way of using it, but it is still a far cry from claiming that it wouldn't exist if every person started to use bitcoins on a daily basis.
