Yes IEO now more popular but it not impressed me if there add a lower volume exchange IEO even at this time i do not follow IEO. Actually at this time cheap market i want buy some coins for the future profit which coin already have added more exchange with expensive developing.
There are lots of cheap altcoins, and it's a lot better than IEO. so we don't need to get in the way to join IEO. Just buying altcoin top 20 is enough
