Sometimes it's really hard to judge a coin that wheather the coin is shitcoin or a genuine one. No one expects a shitcoin in his portfolio. During the ICO even the shitcoins comes with it's fake real uses how you can verify that they are telling the truth or not!!
We didn't have the choice whether it's a good coin or not, so even if that's shit coin it doesn't matter as long as it's trusted by many holders. Just wait for the perfect time for altcoin season and it will be the proof.
