| Verdict | Depends | Depends |
| Best for | Active multi-exchange traders | US crypto investors filing IRS forms |
| Who it's not for | Buy-and-holders using one exchange | Heavy traders with 10k+ transactions . cost and accuracy complaints pile up |
| Privacy | ISO 27001-compliant per Koinly's own materials; one source references an unverified data breach.⁷ | One known incident: a 2022 third-party breach exposed some users' personal info; CoinTracker says its systems and crypto funds were unaffected. |
| Support quality | No reliable evidence in reviewed sources | Reddit reports of unresolved tickets and refund refusals |
| Public sentiment | Long-term users report reliable tracking, but plan confusion and API-key security concerns recur across reviews.¹ | Mixed: users value the integrations and Coinbase ties but repeatedly report wrong tax records, denied refunds, and security worries.15 |
| Biggest gotcha | API-key access means breach exposure sits with the vendor; one source cites a Koinly data breach⁷ | Wrong cost-basis records reported even after purchase . verify before filing16 |
