The term intrinsic value has two meanings - financial and numismatic. Financial meaning only applies to stocks and other financial instruments, it's basically an objective value of how profitable this instrument can be based on its economic performance. This is not applicable to Bitcoin, because Bitcoin generates profit purely from speculative trading. The second meaning, the numismatic one, applies to coins - it is the value of the metal a coin is made of. Bitcoin is digital, so it has no intrinsic value in this sense.

There's nothing wrong with not having intrinsic value. Gold doesn't have one, gems don't have one. In fact it's good that Bitcoin is money in pure form, just like fiat money, because other uses don't interfere with its supply and demand.
