Made some updates to the Zcash mining profitability spreadsheet to include live cost to 51% attack the network and the amount of ASICS required to do so. Please let me know if you have any critiques to the math on the calculation
The best way to think about it is. At today’s price how much zec could I purchase with the amount of money planning to spend on mining equipment. Then compare that to how much zec your expected to earn over the course of the year based on today. Then discount that by 50%.
