But nobody will give a other person money for something that the person has get for free in the past. You need ever a initial value. This is a question of psychologie and human envy
Money is inherently worthless, no matter what currency you look at. I agree it won't have value until someone buys NEX, but again this goes back to the market. If the market thinks it's worth something, it will be worth something.
Worth isn't a tangible property. Worth doesn't mean bitcoin, or USD or NXT or anything like that. Worth is what people determine. A currency doesn't have to be exchangable to have worth, therefore it does not have to have a price to acquire worth.
Scarcity alone gives something worth. When the free NEX is over, it then becomes scarce. Enough alone to give something value.
