I've always wondered how these mining calculators work. Now I saw a formula:
Reward = ((hashrate * block_reward) / (current_difficulty * 2^32)) * (1 - pool_fee) * 3600
(Can be seen via
this page.)
My question therefore is: to which period does "reward" refer to? To an hour, a day or a month? The number 3600 appears within formula, which makes me think it could be an hour. However, the result of several dollars per hour seems a little bit too high. That's why I'm unsure. Any suggestions?
