Many coins are below ICO prices due to this recent dip and I think this is the last dip that we will experience and bull run will start soon. At this moment, it's time to accumulate some quality coins, what coins are good to buy?
Below ICO price is usually happen to a coins which is not listed on official exchange yet.
Yes this is good time to buy on decentralized exchange like IDEX or EtherDelta, and once your coins listed on offcial exchanges it will be good for you, but your coin never listed or it's scam, that's bad.
