However, we can consider it roughly constant in the short term for our purposes here, as over a 720 block period (one day) the reward drops ~0. Section II provides updated calculations based on Section I. Take the reciprocal of the probability to get the average number of hashes to solve a block. From the drop-down menu, select Settings. Divide by 115792089237316195423570985008687907853269984665640564039457584007913129639935, which is the maximum value of a 256-bit number. Nonetheless, you can get a rough idea using this method. Right now it is a little less than 11 XMR, but I m going to just use 11. Disclaimer: The reward changes based on how many transactions are included in a block. Generally speaking, the formula to determine the hashrate needed to mine 1 XMR per day is: n = (Network Hashrate) / (720 * Avg Block Reward) What CPU / GPU would be required to solo mine 1 coin a day. Finally, Select In the left-hand column, select Settings from the list. 20 June 2017 Update to Section 1: Hashrate: ~87. To find out the exact reward at any given time, you could go to a block explorer (http://moneroblocks. Additionally, the optimistic (50% probability) and pessimistic (95% probability) estimates are shown as well.
