I believe the 6 decimal, 1 CKM = 1 Crypto Kingdom Million (Markka) solution we went with is still a viable option.
And a more logical one.
As long as we get the game currency listed on some external exchanges, I don't worry about decimal places at all

That won't really be a hard job, we just need to gather some
BTC to pay for a listing on some exchanges.
That's it.
What our challenge is, it's getting a good dev that's going to make a GUI for our website.
The things we're talking about are secondary..
