It's back to square one if you are holding a coin or token for long term and finally altcoin season comes and the token or coin surge in value but has no trading volume on exchange, all your efforts and pain while holding is total waste, do not hold tokens or coins that have no demands, real use cases are what makes them very demanding
i agree the coin with no demand or real use case is not really a good to hold
price can drop at any time if the supply will not match the demand.
indeed the price increase can be seen from the influence of demand and the total supply of coins or tokens, because if more demand means that the tokens can be very expensive because many people will buy them.
