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.
