Hey thanks for this,

I think this mining calculator are much more accurate than most of mining calculator out there, what I like is the site are automatically input the difficulty, block reward, and difficulty change with the latest updated data. This would make the mining calculator can calculate the latest profitability with the latest data.

I think the site is lack of coin/token can be mined since it's still less than 100 and the mining hardware is still not all listed yet.
