Many of the coins in Primes belong to hashstakers, which could have came from hashpoint miners.
Technically impossible. Hashpoint miners were free to withdraw their coins at any time, unless they put them into HashStakers, which happened AFTER the initial pre-mine distribution.
Well, actually it is possible if most Hashpoints were fake, generated by the likes of Craig, and never really left GAW's possession. Which is why all those figures are meaningless no matter how you look at it. Also consider that GAW never clearly separated their own coins from "investors" and "customers" coins and were caught selling "borrowed" coins on Paybase.
The fact is that there are a lot of coins in GAW addresses that technically belong to users. So counting all prime coins as belonging to gaw is inaccurate.
And if they knew how many hashstakers they sold, they could have guessed how many coins would stay in zencloud.
The point here is that the 40% includes anything in zencloud which is prime staking.
Zencloud has nothing to with prime staking. Zencloud is simply paying coins out of premine, it was paying out before Primes even started staking, and after that it's still paying out of premine and not out of newly staked coins.
We don't know if 40% coins were given to Hashpoint miners. There is no record of that, in fact I don't even know where you got that number from - got a link or something?
Hashstakers didn't have to be loaded with coins, so Hashstaker sales weren't a good indicator of how many coins would be locked up. But GAW did try to hype it up and lock in as many coins as they could, I'll give you that.
Bottom line - it's pointless to try to make sense of these numbers. The whole thing is obfuscated for a reason. The few instances when GAW got caught red-handed (premine moving to Cryptsy or being sold off on Paybase) should be a good indicator of what the whole charade is about.
https://hashtalk.org/topic/22975/initial-paycoins-of-12m. It actually says 60%, I thought I remembered him saying 40% but I may have gotten mixed up.
The fact that zencloud was paying before the staking began doesn't actually mean anything. The staking is cumulative, so even if they waited until after six months to stake, they still should get the same total staked, possibly without the compounding. So they could technically have depended on future stakes for payouts. (I haven't looked through the code, but I understand that's how POS coins usually work. May be wrong.)
But either way, taking the number of coins right now in primes is not a good proxy for how many gaw has, because many if not most of those are actually owned by customers.
