# Mining Profitability of BTC and BCH

When I review sites like fork.lol and they speak of Mining Profitability of BTC and BCH, how are these calculated? I am trying to figure out how mining profits change between these two coins and how someone determines which one is more profitable, and why the highest profitability switches between BTC and BCH?

mining\space profitability$$\frac{\mathrm{BCH}}{\mathrm{BTC}}=\frac{\frac{(\mathrm {BCH\, block reward + estimated\, total\, transaction\, fees \, in \, a \, BCH \, block})\cdot (\mathrm {BCH\, exchange\, rate\, (in\, USD)})}{\mathrm {BCH\, block\, difficulty}}}{\frac{(\mathrm {BTC\, block reward + estimated\, total\, transaction\, fees \, in \, a \, BTC \, block})\cdot (\mathrm {BTC\, exchange\, rate\, (in\, USD)})}{\mathrm {BTC\, block\, difficulty}}}$$

• Yes, average transaction fee * average number of transactions in a block. Bitcoin's difficulty algorithm is: bitcoin.stackexchange.com/questions/5838/… while Bitcoin Cash' algorithm is not so simple: yours.org/content/… – MCCCS Nov 18 '17 at 7:33
