Not an expert in tokenomics, but the fact that $ZING has no maximum supply disturbs me. Let's say, $SPS and $GODS have it (according to coingecko.com), and that makes them more interesting to investors, as I see it.
Not sure how the mentioned games will keep rewarding players when the tokens end. Maybe, they'll decrease $SPS /$GODS rewards when the USD price is large due to scarcity of the tokens? No idea.
If everything is fine, $ZING might enter large exchanges one day, so worth thinking about this. Let's say, Gods Unchained probably got good funds when they entered the last bull market at its end in October 2021.
There's a few reasons it doesn't have a cap, it's not meant to artificially create scarcity and to reward players and investors over many years to come in different ways. We also have plans to use the token, both as players and as the project, so it'll be more a balance between how much is being created compared to demand and how much is being burned. While it doesn't have a cap it doesn't mean we'll just wildly keep printing millions.
Hive works similarly in a way, once the inflation drops down to 0.5% yearly it'll go back to being inflationary as far as I understand.
