If you use various FIAT currencies in your account, there will be error messages for those that are not your main account currency.
You can view (and change) your main account currency on the Account Settings page. We recommend to use the FIAT currency from the country you are living in.
The second FIAT currency will be treated as a foreign currency in our system and will be assigned a cost basis of 0 if there is no matching import.
Please add all second FIAT deposits as 'Income (non taxable)' since this transaction type is taken into account for the purchase pool and has a Fiat cost basis.
You could deactivate both sliders in the extended tax report settings that warnings for foreign/other FIAT currencies are not shown in the capital gains report:
This slider is no longer available for Germany because foreign currency gains must be included directly.
If you have fees during deposits then please add them separately as "other fee" transaction and not as part of the deposit.
If you live in a country that taxes income higher than capital gains, please use the following work around:
For example, if I have the following trade that showing a fiat deposit warning:
Buy: 0.15 BTC Sell: 40 USD
Convert it to your home FIAT (example: CAD) using the conversion rate at that time (which can easily be retrieved from CT by editing the transaction and using the "Sale value in CAD" value):
Buy: 0.15 BTC Sell: 50.78511838 CAD (the equivalent of $40 USD)
Please be aware that by holding onto the other FIAT (i.e. CAD) for a little while after ‘earning it’ (as it was listed as income), and before buying cryptos with it, you can lose or gain a little home FIAT (USD).
