Nice review thanks for the link.
I like his presentation, it makes it a lot more easier to listen. So I learned from this video that the competitors of Gizer are: Enjin coin, FirstBlood and MobileGo. Never heard of the first two, but the last one is very promising.
Thanks a lot for sharing this link.
Always nice to see reviews about project you support. I think GIZER is a much more stronger platform then the coins in the review.
