mining specific coin instead of mining the algorithm on nicehash for example is far away from calculator results
i mined criptoreal for 24 hours
calculators say above 400 CRS i will mine
but on hashpool.eu i just mined 211 CRS
The hashrate and difficulty of a low cap coin can vary drastically and the calculators give an assumption of the earnings based on current hashrate which is never the case when mining.
This is not the case with Gincoin, Crypt0zone simply completely overestimates the earnings. Consistently around 30%.
You can take what they predict and minus 30% from it and then take into account fluctuations due to global hashrate.
