Of course these 25 coins are very good for the start. But I hope they also put a strong focus on the smaller coins that are not so well known. There are far too few trading opportunities for these
ONAM has done its homework and chosen the right first coins to list in their exchange. Important and popular coins should be in list to grab many potential traders.
I agree, Those common and popular coins will going to help them too on making a volume for their exchange. When they have some good volume getting more traders will be easy.
True, I think they made the right decision in listing these popular coins first as they're more stable than others.
