Of course we must see the situation and condition first before investing. Their price down because investor already invest their money for 3-6 months ago. so they better pull out some profit first and wait and see the market condition. So when their price already dumped enough then its time for buy and hodl until reach the moon with the note that project really is good enough or the developer still keep on the track about their roadmap. But if your project really has something value inside, i think after they listed on exchanger, their price not will low than ICO price. So now adays investor already being smart to choose which one is good and which one is bad.
