Added NiceHash 'coins' for reference.
You can now compare mining available coins to mining the same algorithm directly on nicehash, rewards are in BTC.
Current price and average 24h price come from NiceHash api, so the rewards and revenues are just a multiplication of `hash_rate * price`
Exchange rate link will take you straight to NiceHash orders for given algo.
Also listing current nethash(speed from NiceHash api) with change from 24h average.
I will add 3day and 7day profitability calculation, once I gather enough prices to calculate the average.
Happy mining
