What CryptoTaxMatch will and won't do
- It never invents a purchase price. Missing cost basis is shown as unknown, not zero.
- It never deletes your records. Proposed fixes come with a reason, and you decide.
- It doesn't calculate tax or replace your tax software; it helps you find what to fix in it.
- It's a beta: tested on sample files, not yet on every exchange's real export. See what's tested.
