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
High price and no volume means that there is some sort of manipulation going on in the trade pair and exchange platform.
This is one reason why i do not always follow coinmarketcap, i prefer to visit the exchange and see things for myself.
It is hard to identify tokens with no worth, but with good research strategy, you can have an advantage
