Missing source files
An old exchange, broker, or wallet export may be absent from the import set.
Holdings reconciliation
When your imported crypto history says you should hold the wrong amount.
Gainz compares what you declare you currently hold against imported buys, sells, sends, receives, and available lots so the gap becomes a review queue instead of a mystery.
Common causes
Holdings gaps usually point to missing context.
Owner transfers
Sends and receives may represent movement between your own accounts rather than sales.
Disposals or losses
Some sends may need research as disposals, trades, lost assets, fees, or other documented events.
Duplicate history
Full-history exports can overlap with yearly exports and inflate activity if imported twice.
Gainz approach
Make the discrepancy explainable.
The goal is not to hide a mismatch. The goal is to identify what records, user decisions, or professional review are needed before relying on generated reports.
Not tax advice
Gainz helps organize reconciliation evidence. Classification decisions should be supported by records and reviewed with a qualified tax professional.
