hashrate

Bitcoin mining profit calculator based on difficulty.

Uses difficulty data from the blockchain.info API and extrapolates data with simple linear regression (via. linefit).

If used in production, I strongly encourage these results to be verified with the bitcoinx profit calculator.

Note: this calculator currently uses a static 25 bitcoin reward. It won't work very well for calculations before 2013 or after 2016.

Note also that I designed this to be used in Rails, so it caches the json from blockchain's API for six hours before requesting it again.

$ gem install hashrate

Or, if used in a gemfile (like in Rails):

gem 'hashrate'

How much would a 100 GH/s machine have earned running for the last six months?

>> require 'hashrate'
=> true
>> now = Time.new.to_i
>> Hashrate.earning(now - (60 * 60 * 24 * 30 * 6), now, 1000 * Hashrate::GH)
=> 201.08229099734106

201 bitcoins - wow!

What do we expect this machine to earn in the next six months?

>> Hashrate.earning(now, now + (60 * 60 * 24 * 30 * 6), 1000 * Hashrate::GH)
=> 9.280482914219407

Only 9 bitcoins - ouch. Should've started running it six months ago.
