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
Demand depending of the utility of token/coin, if the token useless demand will be stagnant and no more new investor buy it, its really hard to find new ICO coin without utility, in roadmap + whitepaper we will see the utility of token/coin but after ICO some problem come and the utility cannot be implemented like at the roadmap. then the project dead withour volume transaction
