Hi there, we have not yet finalized the method of distribution, whether it will be a bitcoin snapshot, raiblocks snapshot, airdrop or some other method, i'm aiming towards even and fair distribution, if you have suggestions you are welcome to post your idea! i noted that another user mentioned it would be a good idea to do a similar process to what the ZClassic team are doing, which is merging ZCL and bitcoin snapshot together, there is a possibility i could do this combined with the donators fund, although it leaves the question of, is it fair? still very open to discussion.
Distribution method proportional to snapshot of some currency won't be distribute evenly, it would favor the rich. There is an option of normalizing airdrops (e.g. any address with positive balance will receive exactly 10 Stones), but it's not feasible for bitcoin-based currency where any distinct entity may have contol one address or millions. Would work with ethereum, though. You'll just have to filter out big ethereum mixer addresses which is pretty easy to do. So, normalized airdrop on good-looking ethereum addresses would work.
Airdrop faucet will be more or less fair and even, but it'll be a strain on community.
One more possibility would be to airdrop to identity management blockchains like Civic but those are unpopulated and will be for a few years more.
One more cool option is airdrop to some social network or other OpenID provider. Popular networks are full of bots and dead accounts, but there are a few that would be cool to do (e.g. airdrop to Github accounts, which are largely genuine nowadays).
