Thanks for the tool - could you put in a modifier to change what the expected added hashpower on the network is? In other words, people have repeatedly brought up that you cannot double hashrate month after month, it would require exponential gains in productivity figures, that would require double capacity selling and money thrown at the hardware month after month - it doesn't work this way in real life.
Agreed!
this uniform % rise each month is unsustainable and incorrect. Doing a bottom up forecast yields higher difficulty in the next 2-3 months (as the new 28nm asics come out) but lower difficulty rise afterwards (because each asic company most likely ships the same amount each month, and definitely will not be shipping double the amount of asics each month.
1. probably need a way of adjusting the difficulty rise separately for each month that is separate for each month...
2. might be good if we could specify TH increase for each month, that way we can fill in our own forecasts, or use ones like DeathAndTaxes has produced... to see what the network effect is.
