Never loose faith, ICX is one good project from thousands out there which stood the test of time, maybe it won't reach the ATH since the market matures and the fomo from 2017-2018 won't be as hard as it was, but I think Icon have a lot of room to go to $1-2 again.
It is quite possible that it will be so. This project seems to me a really good investment option. And if you already have coins, then selling at current prices is definitely not worth it ... the altcoin season is ahead.
