All transaction prior to April 2013 show up with a valuation of 0.00 EUR in the final tax report. Is it possible that the oracle isn’t available for those times?
CoinMarketCap (CMC) does not provide Bitcoin, Litecoin or Namecoin prices before 5/2/2013 but they do have an established market price since at least 2011.
Classifying all mining, payment and other transactions as ‘OTC’ is not a viable workaround here. The whole purpose of using Accointing is to automate the process and differentiate between different types of transactions. Coinmarketcap is not acceptable as sole single price oracle for any user who was involved in crypto before mid-2013.
