Doesn't matter if zarhex exchange is a big or a small currently, in any way that is a real place where we would be able buy or sell these coins. On my mind only a presence on an exchange adds a value to the coin, i.e. when someone wants to buy it and there is a place where he can do this.
So many new coins are appearing last days, those could have a nice whitepapers, famous developers, sweet promises, but despite of all of this investors and bounty hunters are waiting months or even years until they get listed at least on one exchange, meanwhile their coins remains as just digits on monitors without any real value. I don't like to wait so long, i prefer when the coin has any available exchange asap. So i consider as a big plus that Zvault will be listed soon at least on zarhex exchange.
Other plus is PoS, because it doesn't require a specific tech knowledge and equipment in comparizon with PoW.
