Thanks rdw, however:

As already mentioned above staking that wallet is just asinine. First of all, such amounts should be offline for safety. Second, they're robbing their own bagholders. Third, it makes the network more centralized and if their node goes down it would probably cause some lengthy block times until diff adjusts. We already had hours-long blocks when they moved 2 million coins. Nice people. Anyway, that's between the "team" and the bagholders so whatever.

But how about the remaining coins still not accounted for:

5 million IONs will be available through the Initial Coin Offering (ICO) in exchange for BTC and a wide selection of other cryptocurrencies.
3.4 million IONs are allocated to ionomy.com and shall be distributed as structured incentives to gamers through the gaming applications designed by ionomy.com.
2.5 million IONs are reserved to pay bounties for coin development. done

And the ICO bitcoins of course - where are those?

As for the XPY burn - they claimed to have collected 10 million XPY but only burned about half of it. AFAIK they haven't even published the addresses of the coins that haven't been burned yet.

Edit: There is nothing new in this info BTW, the dev bounty and the XPY partial burn were known months ago. If you asked recently and got these answers you're just being played. Although there is some weird movement from what was presumably the old dev bounty address but I don't know if that's even worth looking into:
