Ah got it.
Yeah, we thought about that. We really did. But the thing is we also work closely with individual creators to be able to give out a certain number of free Keys to their specific stories as well.
That is something the community hasn't really seen yet because the Dev team is still finalizing it, but once they're done we'll be able to do cool free Key giveaways for specific series based on whatever a creator feels like doing.
For instance, if a specific story isn't selling well and the creator wants to get more people to try their story, they can say "hey Tapas, why don't you give everyone 5 free keys to my story so people will come try it out".
That wouldn't be something we could do with a Coins only system because people might take those Coins and spend them on a story that creator didn't control.
When we give away Coins it's something Tapas is doing and Tapas will have to pay the creators whose Keys are bought with those Coins. In the future when we give away Keys directly, that is something Tapas won't have to pay for because the creator gave us permission to do it.
So basically, in a nutshell, Coins are the currency of the entire Tapas system and Keys are controlled by individual creators. And the number of free Keys we provide to readers is a discussion we have with every single creator involved with the Key program.
