Bitcoin Forum

I decided to write a small tool to look at past mining investments. Besides being a regular bitcoin calculator, it can also analyse data to answer questions like: "If I had bought 3Ghash in June, how much would I have made?" Here's the link:

Maybe we can learn something from the past that will help us predict the price/difficulty movements in the future... Anyway, suggestions/improvements and overall feedback are welcome :)

I like the layout, very clean.

Thanks

Thanks :) I will probably add more options and statistics soon, but I am still thinking about what would be a good indicator. Those calculators that estimate the earnings considering an X% difficulty increase are far from accurate..

Suggestion, something like this : http://dl.dropbox.com/u/2479243/bitcoin%20ROI%20.xlsx

So I don't have to change difficulty, price, and exchange rate manually.

I pay my elec bill in CAD but You can remove anything Canadian related.

as a general rule, To be safe don't plan on mining if your electricity price is higher than the world average. (unless fpga)

price and difficulty are closely related with electricity cost.

I don't have MS Office right now, but I will check it later on Windows. I took a peek using google docs and there are a lot of things there. Are you talking about ROI (cost to generate/sell price)?


I also agree, but I think that in the following months we will see a shift towards FPGAs. If a relatively cheap (say 1$/Mhash or so) FPGA becomes available, the network will adjust and mining with a GPU will not be profitable for most people. Of course there will be a transition period (not sure how long, though...).

fpgas will stay negligible for a little while.  At least this winter.

Would you consider open-sourcing this?

Maybe, but not right now. I still have a few issues to iron out...
