Monero nethash before the fork 1200 MHASH, nethash after the fork( block 693) 176 MHASH . the nethash will continue to decline until we reach 720 blocks.
At 176 MHASH we got around 352 000 gpu's mining (@500h/s). This should take some load of ethereum and zcash and boost the profit all over the board.
Nah, looks like the difficulty is going back up, but it could just be a lump of miners shifting over.
