Kraken was founded in 2011. In fifteen years of operation it has never experienced a hack that resulted in customer fund losses. This is a record that no other major exchange can match. Binance has been hacked twice. Bybit suffered the largest crypto hack in history in 2025. Coinbase has never been hacked but also has not been operating as long. Kraken’s security track record is not a marketing claim — it is verifiable history.
In 2025, Kraken completed its acquisition of NinjaTrader for $1.5 billion, the largest deal in crypto-to-traditional finance history. This fundamentally changed what Kraken is. It is no longer just a crypto exchange.
The Verdict First
Kraken is the right exchange for security-conscious traders at any level, European users who need MiCA licensing, traditional finance investors migrating into crypto, and intermediate traders who want competitive fees with institutional-grade transparency. It is not the cheapest option for small infrequent buyers.
The NinjaTrader Deal: What It Means for Users
The May 2025 acquisition of NinjaTrader brought nearly 2 million professional futures traders into the Kraken ecosystem. For existing Kraken users, this created access to over 11,000 US-listed stocks and ETFs, tradeable commission-free alongside their crypto holdings. For NinjaTrader’s professional client base, it provided a direct on-ramp to crypto through a platform they already trusted.
This positions Kraken similarly to what Coinbase is attempting with its 2026 stock trading launch, but with a more established base of professional and institutional traders rather than retail beginners.
Fees: Simple Interface vs. Kraken Pro
The instant buy and sell interface charges around 1% plus payment method fees. This is not competitive and should only be used for very small or one-off purchases where convenience outweighs cost.
Kraken Pro charges 0.25% maker and 0.40% taker at the entry level, dropping at higher volume tiers. High-volume makers can reach 0.00%. These rates are competitive with Coinbase Advanced and significantly better than Coinbase’s simple interface, though slightly higher than Binance and OKX at equivalent volumes. Futures fees are on a separate schedule and remain competitive.
Proof of Reserves: Quarterly Cryptographic Audits
Kraken conducts quarterly cryptographic Proof of Reserves audits that allow individual users to verify their balance is included in the exchange’s total holdings. This goes beyond standard financial audits. You can independently confirm, using your own Kraken account data and the public Merkle tree, that your funds are represented. OKX offers monthly PoR. Most other major exchanges do not offer verifiable user-level PoR at all.
Security Architecture
95% of deposits are stored in air-gapped cold storage across multiple geographic locations. Mandatory two-factor authentication. Support for YubiKey hardware security keys, authenticator apps, and biometric verification. No successful client fund hack in fifteen years of operation. There is no SAFU-style insurance fund, but the cold storage practices and track record provide a different kind of confidence.
Who Should Use Kraken
Right for you if: Security track record matters more to you than fee margins. You are European and need MiCA-licensed services. You are a traditional finance professional who wants crypto access through a platform that also connects to equities and futures. You value cryptographic Proof of Reserves transparency. You want a full product suite without the regulatory history of Binance.
Wrong for you if: You are making small infrequent crypto purchases and will use the instant buy interface, where fees are high. You need the lowest possible fees at high volume, where Binance and OKX have an edge. You expect fast verification or responsive customer support, where Kraken has historically been slow.
Bottom Line
Kraken’s fifteen-year security record is its most compelling argument and it is a strong one. The NinjaTrader acquisition makes it a serious contender for traditional finance professionals looking for a unified trading environment. Its fees on Kraken Pro are competitive. For anyone who places security and transparency at the top of their criteria list, Kraken belongs at the top of the shortlist alongside Coinbase. Use Kraken Pro from the start and avoid the instant buy interface.
