Verdict
In our overall rating Kraken Pro leads with 4.4 against 4.0 for 21bitcoin.
On a €1,000 purchase you pay €3.80 less at Kraken Pro.
For most investors Kraken Pro is therefore the better choice.
21bitcoin has established itself as an Austrian Bitcoin app across German-speaking Europe, valued above all for a transparent fee structure starting at 0.79%. The provider is licensed by Austria's Financial Market Authority (FMA) as a virtual asset service provider and deals exclusively in Bitcoin. Users single out the automatic transfer to a personal wallet above defined thresholds as a genuinely useful security feature.
The savings-plan approach is refreshingly uncomplicated: standing orders are invested in Bitcoin as soon as the money arrives, and the flat wallet-transfer fee of 0.00001 BTC is widely seen as fair. For investors in Austria, Germany and Switzerland looking for an FMA-regulated alternative to the Swiss Bitcoin apps, 21bitcoin reads as a solid option. Total costs of €7.90 on a €1,000 trade sit in the middle of the field.
Because Bitcoin is the only asset on offer, 21bitcoin is not aimed at investors who want a broad crypto portfolio – a limitation some users do point out. The absence of two-factor authentication in the app and the €15 minimum order also leave room for improvement. That makes 21bitcoin a good fit for Bitcoin-focused investors in German-speaking Europe who care about cost transparency, automatic wallet transfers and Austrian regulation.
Kraken Pro is the separate trading interface from Kraken (pro.kraken.com and Pro mode in the mobile app) and is aimed at active traders. Unlike the standard platform with flat 0.99% fees, the volume-based maker/taker model applies here, starting at 0.25% maker and 0.40% taker, decreasing as 30-day volume rises. Account, verification, and asset balances are shared between both interfaces.
The order set covers market, limit, stop-loss, take-profit, trailing stop, iceberg orders, and bracket/OCO combinations. Margin trading is offered with up to 5x leverage depending on the pair, with selected assets reaching 10x. The availability of margin and derivatives is tied to MiFID II requirements in some EEA countries and is handled via Payward Europe Digital Solutions. Charts, order book, and API access (REST and WebSocket v2) are described in user reviews as sufficient for active strategies; the learning curve compared to the standard interface is occasionally criticized.
Kraken Pro is considered particularly suitable for active traders who value pro order types, lower volume-based fees, and margin features. Those primarily looking for savings plans or simple spot investing will find a more fitting setup on the standard interface. This comparison does not constitute investment advice.
