NEO Holders will once again be treated to an additional airdrop of a NEP-5 called the NNC token, simply for holding NEO coins in their compatible NEO wallet(s). Similar instances have already occurred with Ontology and Master Contract Token.
The snapshot of the blockchain will take place on June 27, 2018. Users holding NEO in a compatible wallet will be rewarded with .1 of a NNC token for each 1 NEO coin they hold.
One (1) NEO coin is currently worth $53.08, at the time of writing this article.
NNS plans to airdrop its NNC tokens to NEO holders in the ratio of 1 NEO=0.1 NNC. The snapshots of NEO holdings will be taken on June 27th after the completion of NNS contract testing and no security loopholes are found. NNC will be airdropped within one week after that.
