I recently added a public-address-wallet to CoinTracker with a long history of small recieves from mining. I paid taxes on these in a previous year using a slightly different USD exchange rate, so I need to adjust my basis on each TX.
What can I do to bulk adjust my basis? I can produce a spreadsheet pretty easily, but filling each and every one into the website by hand is not going to happen.
I can write some python if there is an API available.
