Want to know what the true value of each coin right now should be?  1 NRS = $7.74USD = .014btc (based on mining on 8 cores at DigitalOcean)

8 cores cost per hour = $.238
8 cores (12.86 hashes per minute) = 771.6 hashes per hour
Network hashes per hour (currently 558 per second) = 2,008,800
Probability of mining 1 block (80 coins) in 1 hour (network/personal hashes per hour) = 1:2603

So, theoretically it will take you 2,603 hours to mine 1 block of 80 coins with 8 cores on Digital Ocean.

2603 hours * $.238/hour = $619.51 per block

$619.51 per block / 80 coins per block = $7.74USD

$7.74USD = .014btc


Please feel free to double check the math.
