i think batter we hold our coins so we can get some good price value bcoz if someone selling it under 500 then he is doing big mistake its price will rise more up soon its just first day of its trading
i think it is mined before listing on exchanges bcoz after listing on exchange a lot of people will mine and difficulty will increased if you use calculator to check mining profitablity then with its current difficulty its the best SHA256 coin to mine supposing its price at over 42coin
so mine silently and get some decent amount of 21c at low difficulty
