Just started mining Ryo and the profit is showing $0.00 but it's mining ok (hash rate is 7.4 kh/s)
It looks like it's removed from CoinCalculators.io main listing due to low volume.
You can manually add it back via the Options dialog, Statistics Provider section, where you can add a CoinCalculators JSON URL:
