Typically many assumptions are poorly documented.
May 31, 2018· For example, let's take the easiest target that's ever existed in Bitcoin: the genesis block. The probability of any single hash being less than the easiest target is 1 in 2³². That's one in over four billion. Therefore, we can reasonably expect somebody to run 2³² iterations of the mining problem in order to find a proper hash.
Ideally, I would then use this information to estimate mining profits in the future (6 months, 1 year, 2 years, 3 years, etc) using the reward curve and projecting a difficulty over time. It would also be cool to mess around with the price of Monero over time, for example assuming the price will increase 5% a month on average or something like ...
