I think it is good. The miner will push the prices for the cryptonight coins up. the difficilty will increase extremly. If you mined 300 etn per day you will mine only 3-5 in a few weeks. the price will go up. hold your mined coins and smile all day 
I don't know why people operate under this misconception. Yes it has happened a couple of times, but, that was when coins were in a bull market already. Logically, and it happened with SIA, the faster miners are reaping rewards, the more supply is driven to the market. That drives prices "down" not "up". Especially when said "miners" are trying to recoup huge hardware costs.
