Your profitability calculations for Anoncoin and Kruger coin are wayyyy off....
Not really - the exchange price is a weighted calc based on a certain depth related to a conversion of BTC. So, it will look a lot smaller than other sites (potentially) until the markets get more established.
That being said, if the difficulty I was reporting was off, that would make the profitability off. Was it accurate? On both these coins I use data from a third party block explorer, which may explain the issue.
