| Meaning | More was sold than imported |
|---|---|
| Effect | Often cost basis 0 and a gain that is too high |
| Fix | Reload the missing source, do not hide the warning |
Do not look at the report button. Look at the asset, wallet and date of the first negative point. Immediately before that, an inflow is missing. That is the same gap chain.report shows as a balance discrepancy.
A CSV only for the current year, depot splits in CoinTracking, a transfer to a hardware wallet that was never imported, a DeFi outflow without a counterpart, duplicate tickers without a contract address. The software is rarely “broken”. The history is incomplete.
1) Import the same history into chain.report. 2) Open the wallet and asset with the gap in CleanUp. 3) Reload the missing exchange, an older CSV or the counterpart wallet. 4) Generate the report only after the balance closes.
No. A small negative balance often flips an entire lot to cost basis zero. The gain then jumps far above the economic result.
That hides the gap. The tax office will still ask for the origin. Reload the missing movement instead.
Yes, as one source. You still have to reload the years, wallets and chains that trigger the warning.
This guide structures the data issues and common German administrative practice. It is not tax advice. The assessment in your case stays with you and your tax advisor.
Import your CoinTracking data and open CleanUp. The warning becomes a concrete gap with a next step.
