TL;DR: The "Cost" column in the summary table on the Realized and Unrealized Gains page only reflects the value of the coins you still own. It does not include the cost of assets you've already sold. For a complete view of your total original investment, refer to the "Realized Gains" table via the blue link below the summary. If, for example, you bought 1 BTC for €100 and sold 0.5 BTC for €60, your cost column will only show €50 for the remaining 0.5 BTC.
Why does the Cost column seem to ignore part of my spending?
The cost shown in the summary table reflects only the current value of the coins still in your possession. If you’ve sold some of your assets, the cost of those sold coins disappears from this column and is instead factored into the Realized Gains.
Let’s break it down:
You buy 1 BTC for €100.
You sell 0.5 BTC for €60.
You now have 0.5 BTC remaining, which cost you €50.
On the Gains page:
The Cost column will show €50.
The Realized Gain column will show €10.
The other €50 (from the sold portion) is not part of the Cost column anymore.
If the current BTC price is €60,000 (instead of the outdated €3010.74 used previously), then:
Your 0.5 BTC is now worth €30,000.
Unrealized gain = €30,000 - €50 = €29,950.
Where can I find the full amount I originally spent?
To see your original investment including sold coins, go to the Realized Gains table (linked in blue below the summary). There, the Cumulated Cost field shows what you spent on both sold and held coins.
Why doesn’t the Cost column always equal what I paid?
It only tracks what's still in your wallet. If you’ve sold part or all of an asset, that sale moves its cost out of the summary and into your Realized Gain calculation. That’s why you won’t see €100 in the example unless you look at the Realized Gains table.
Can I use the Cost + Gain/Loss columns to estimate my total spend?
Only if no coins have been sold. Once sales occur, the Cost column no longer reflects what you spent in total—only what’s left. The most accurate way to view your full investment is through the detailed gains breakdown.
Summary
The Cost column is not designed to track your total investment. It’s a snapshot of what your currently held assets cost. For a full breakdown, always refer to the Realized Gains table where you’ll find Cumulated Costs and realized profits or losses.
