The first pure POS success should be NXT, the pure pos2 were popular, especially for free, you sell, who to see active community, completes the peripheral application. 2 tokens personal value is 2014 of the mainstream, after all, many mainstream concept, active community, peripheral application has the funds to promote.
I think so.
I think NXT comm C2 is a good choice, not propaganda, not ask you to buy, just can know the technology and development.
