AI AnalysisFees & Costs

The reviews present a mixed picture when it comes to fees and costs: on the one hand, low fees are mentioned positively several times; on the other hand, users criticize high fees. According to user reviews, the perception of costs is therefore not consistent.

Some users report that the app does not open immediately, which makes usability appear limited from the perspective of individual reviews.
Features & Offering
According to reviews, users are rather reserved about BISON’s offering, mainly because of the limited coin selection. Many users would like to see more coins or cryptocurrencies; additionally, an API for Blockpit, staking, savings plans, as well as an iPad or Mac version are mentioned occasionally.
In the analyzed user reviews, there are only a few recurring statements about features and the offering, which is why this area mainly reveals individual requests.

Overall, the feedback mainly shows additional feature requests.
Stability & Security
In terms of stability and reliability, many users are generally positive about BISON. According to reviews, the app is repeatedly described as reliable. However, some users report app crashes, so from the perspective of individual reviews the technical reliability still has room for improvement.
Regarding stability and reliability, the analyzed user data mainly contains individual critical feedback. Some users report that the app cannot be opened immediately or that withdrawals are perceived as delayed.

Customer Support

Verdict
In our overall rating Kraken leads with 4.2 against 2.5 for BISON.
On disclosed fees you pay €2.60 less at Kraken per €1,000 purchase.
For most investors Kraken is therefore the better choice.
BISON is the crypto app of Börse Stuttgart and is perceived in the DACH region as a provider with a traditional capital markets background. Crypto custody is handled by Boerse Stuttgart Digital Custody GmbH, which is regulated by BaFin. With 26 tradable coins, the selection is clearly limited compared with specialized crypto exchanges.
As one of the few offerings among German brokers, BISON allows free wallet transfers to your own wallets. Staking, savings plans, and an integrated tax report are also available. Deposits are possible via SEPA, instant bank transfer, and credit card.
The trading fees of 1.25 % are in the upper range of the brokers compared and are occasionally criticized by users. The exclusively SMS-based 2FA and the processing time for wallet transfers of up to 24 hours are also seen as room for improvement. Overall, BISON is aimed at investors who prefer an established German provider and are willing to accept trade-offs in fees and coin selection.
Kraken is considered one of the oldest and most established crypto exchanges and has been active in the market since 2011. With over 380 tradable cryptocurrencies as well as savings plan and staking features, the platform is appreciated by long-term investors. The extensive security protocols, including 2FA and account lock, are rated positively.
The trading fees of 0.99% and total costs of €9.90 per trade are in the middle range compared with cheaper providers. The lack of EU regulation or a BaFin license is occasionally criticized. Cost transparency is regarded as limited, which some users see as room for improvement.
Kraken is considered particularly suitable for investors who value a long-established platform with a wide coin selection and want to use savings plans and staking — even without EU regulation.
