Cost basis for USA should include fees incurred to buy AND sell the cryptocurrency. Cointracker Tax Center does not always include these fees in the cost basis. Nor does it consistently deduct fees from the proceeds of a sale. This means transactions have to be manually edited to reflect the true capital gains. This shortcoming really diminishes the value of this product.

US tax rules (and possibly other jurisdictions) allow users to use specific identification instead of FIFO, if they can show how the calculations are done. Specific identification means the user can arbitrarily pick and choose which coins is being disposed of for accounting purposes for each disposal.

For example FIFO (2016), LIFO (2017), LIFO (2018), HIFO (2019), etc. Also relevant for people who move between different tax jurisdictions (e.g. US to UK). Could also be in the middle of the tax year.

As an example - in Ireland the Irish Revenue has given guidance that a 4 week bed and breakfasting rule applies to cryptocurrency asset disposals. Otherwise FIFO cost basis can be used. Currently, CoinTracker has bed and breakfasting set up in the 'Share Pool - UK' cost basis method but this includes the averaging of the cost basis on previous purchases. Review the cost basis methods provided and introduce a cost basis method to account for countries with other requirements for calculating cost basis and capital gains.
