Coins only have value if people accept them as valuable. The userbase ultimately decides whether or not they would accept payment via a certain coin.
If the userbase is not interested in a coin, it will not matter how much hashrate is behind the coin, or how many figureheads try to prop it up. That coin will not have value.
