Kraken's best points are reserve transparency and fee structure. The quarterly Merkle proof of reserves lets users verify their own balance is included, backed by independent attestation. Kraken Pro offers low fees that fall with volume, undercutting most US rivals. The 14-year record with no customer-fund hack is the other pillar, and it holds up against close scrutiny. But there are certain frictions too. A first ACH deposit is held for about a week, new withdrawal addresses lock for around 72 hours, and the cheap path lives on Kraken Pro rather than the default screen. Users who need same-day cash-out or want a beginner-first experience will feel both. Use Kraken if you want verifiable reserves, low pro fees, and a clean long-term record, and can plan funding ahead. Skip it if you need instant cash-out or want a one-tap interface with no learning curve.
