Ab chain is really doing great untill now and hope that they have a good amount of investors now to develop their platform and get more attention from peoples globally. This platform will truely turn out to be the best and also can compete platforms like adsense.
Yeah this platform is reaching new heights everyday. As the ico is in their initial phases I think its the best time to invest in this platform, their token price is reasonable as of now.
On your place I would separate process of purchase for 2 phases, in 1 phase I would advise to enclose 70% from amount, and after to buy in addition by 30% from means ab chain tokens already on exchange. It most likely would increase their amount and helped advancing.
