Anything ("real" or digital or anything at all) can be assigned a value by anybody. This value is also self assigned - if you don't think a laptop is worth 700USD like the maker says it is, you might not want to buy it.
A US dollar bill is at the end of the day just a piece of paper - that is assigned a value (that constantly changes) by the market.
The real question is if the currency has any value to a substantial amount of people. Obviously currency is useless if only two people in the world can use it. However as BTC is now over 2000USD/coin and you can use many payment processors (including stripe), I'd be inclined to say that it does indeed have value - and a use; your assignment of value to BTC may be lower.
