XAYA is a new and more general, advanced project run by the Huntercoin team (including snailbrain who invented blockchain gaming with Huntercoin).  We want to take the learnings from the Huntercoin experiment to the next level with XAYA - but of course, Huntercoin itself is still live and prospering as well.

There was a snapshot for giving CHI to HUC holders, but that was already last year - so if you buy HUC now, unfortunately you won't get CHI for it.
