I am in the same boat as you. Friends in IT, accounts, economics, business, not bothering to "waste" their time. However i do know why.
If Bitcoin doesn't have any usages such as the ability to buy goods and services, then what other usage does it have?
It would be nothing more than a ponzi scheme. The current "civil war" just about proved their point.
Then why are you bothering in posting and earning bitcoin in the forum? if there isn't such use for it? I think you can surely convert bitcoin to fiat money and that is the time you can surely buy it for the goods and services that you need, and in my opinion bitcoin is a good way to save and earn money by means of trading on with some altcoins.
