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
My question is how you got the token, if its a token you bought from an exchange, then you can as well sell it back to them. Unless its just a coin that you got from airdrops and events like that and they happened not to be on any exchange, then everything has turned to waste.
If a coin cant be traded then its as good as useless because youre just holding digits and not real money since there is no way you can actually pull out the money. The main reason most people are investing their time and money is because they need profit and when a coin cant fulfill that, then it should be abandoned.
