The infrastructure looks solid. There are multiple pools. You can buy it on SwissCex, C-Cex, and Mintpal.
So far, not a promising coin. Nevertheless, the critical question is whether it will be actually used in games or not? It is used in Mine Rust, a Minecraft mod. The upcoming 1BillionHex MMO announced to support ZedCoin. This is actually not much, but a start.
Overall, not a good coin. However, if it ever gets integrated into a moderately good game, it will be an instant hit. I bought some for my “probably lost money” category.
