#[0]​ , do you have any thoughts on how to approach tracking cost basis and record keeping in a way that preserves privacy while remaining compliant with tax law? Using something like crypto.com would be easier than spreadsheets for tracking cost basis but is a potential privacy risk . On the IRS side of things, using specific identifier for cost basis instead of FIFO can reduce tax liability, but to use it you must either specify transaction Id, public key, private key, or have sufficient record keeping. Clearly, all but record keeping is a no go from a privacy and security perspective. However, it’s unclear what is “sufficient” record keeping and how to do it in a manner that is as private as possible while holding up to audit level scrutiny.
