If I get you right based on your last response its about getting the right exchange rate to use or is it that you want to do cross exchange of Fiat currencies?

Yes, I want to use the right exchange rate to keep my accounts as accurate as possible, I'm only using the one fiat currency and that's Euro. I have it straight in my head now that the altcoin exchange rate doesn't matter, because that's predetermined by the amount of altcoin I end up with and the euro value I assigned to the Bitcoin "sale" on the other side of the transaction. I just need to establish the best method of calculating that euro value, whether that means taking the value from the original purchase price of BTC (probably too much room for manipulation since I could decide those are the coins I bought at 500 or 980 or anywhere in between Cheesy

), the average purchase price of all my BTC (presently about 760) or from the exchange rate of the day (~840).

Especially looking at those figures, the exchange rate of the day seems to be the way to go. My aim is to record the amount of euros I have invested in each coin as accurately as possible, both for my own profit/loss control and for taxes, etc.

Does it sound as though I'm on the right lines?
