A script to calculate the account balances for each coin given a full transaction report which you can download from Coinbase.
WIP: the account balances currently don't match the numbers from Coinbase. Either the transaction report is incomplete or there are still bugs in the script.
Needs ruby and bundler (gem install bundler).
Then run bundle
Download a full transaction report from Coinbase and place it alongside main.rb
Remove all the crap before the header row.
Then run ruby main.rb to see the balances.
