Ever played any online game with ingame currency? There are no pricetags in dollars. Well at least used to in Diablo III that is possible too. The difference here is item prices in dollar follow their ingame gold value not verse visa.
That's the point I'm trying to make if bitcoin started as a trading tool for something valuable but not necessarily costly (for example game items or pictures) it would have evolved very differently. It's already too late for that since we have almost half of all bitcoins valued in dollar instead of something fundamental.
I wouldn't say it's too late to change that
I just wrote that because I can't think of any.
I'm open to suggestions... and I mean it.
It does't matter, if it happened as you said (game items for bitcoin), then you can know the exchange rate between dollars and bitcoin by knowing the price in dollars of the game items. Dollars, and currency in general are used as the common denominator because it is a more widespread commodity than game items. That's the function of money, to serve as a means of comparison.
It does greatly matter....
In case of online games the ingame currency is more broadly used than dollars. The scenario I was proposing is one where bitcoin would be more broadly used than dollars for some niche market, at least within the community it is used for.
