Well, statistics teaches us that randomly clicking octo explorer transactions will likely show the wallet with the currently highest hashrate.
it's this one:
http://explorer.octocoin.org/address/8NQcJrZgyqJYiNXUuXtbQXn3AKufTSXqmTbut, the octo explorer somehow doen't show it
EDIT:
if anyone has some spare time he could try to trace back this address. if it leads to the first days/weeks it is likely the devs wallet and it means they are still mining with lots of hashrate.
That address is most likely a pool address, as seen here in the link to FusionHash's wallet address.
http://explorer.octocoin.org/address/8dWMopM6t8exAvGc7PQUEtrHdBwgTnktJbIt could be Edric's pool address, it could be a multipool (although i don't think any multis mine octo anymore), or it may be someone solomining (most likely)
speculation leads to no good here at this point so take that as you will
