The blocks he mines are empty.
I think it deserves to be reorged, but itIt is faster to submit empty blocks than it is ones with transactions.
Do you want a high chance at 50 coins
(~85%) or a small chance of 50.1 coins?

Dude is just working with what he has. The other miner who has never moved coins and just crossed a million is wild too.
Honestly, he's selling more coins than any premine too and killing the traders. Kind of a win.
He could get knocked out in several ways though. Do it better, reorg, and so forth.
Pretty kick ass BitAxe with the right set up. I think someone could pool hop too. Mine BTC/BCH or whatever then when 20 mins come on, click over for the Testnet fast block, and back to mining whatever profits.
