Why does the hash suddenly jump so "high"
It's mostly due to one big player '888' that is mining at Bitember:
This would suggest a company is behind it with 150Mh/s mining power. Renting something like this would cost you about 0.05 BTC on Betarigs a day. This should create about 10M Nutcoin a day, according to those stats. It could be more than this, since about 21 million Nutcoin are created each day now.
This means the current cost for creating 1M Nutcoin is 0.005 BTC or 0.5 LTC. With the current prices on Allcoin, you can buy a million Nutcoin for about 0.1 LTC. This means the current market price is five times lower than it costs to make these coins!
A logical reason is that the creation company is putting a lot of power behind the coin because they still have plans for it. It costs them about 1,5 BTC a month, so they must have some sort of a plan.
