Well, I don't think Bitcoin has no value . Why? Because if there is none why many people still into it. Many still gaining income from it. So meaning they valued Bitcoin.
Of course bitcoin has value. We do not waste our time without gaining from it. Bitcoin exist and circulate on the market which make it volatile. Even we cannot touch it like fiat, we can able to used it as a real one to pay for something we buy though it is a product or a service.
