I already participated in Dimcoin ICO which was built on NEM blockchain technology it was the successful ICO but not yet listed on Exchanges . Again one more Comsa which is also doing very well and getting huge investment on that . But Even i am not huge fan of NEM based technology . I always looking for Ethereum based ICO's .
I also just joined DIM ico and waiting for exhange. And didn't make enough research on NEM yet.
