The five areas head to head
AI AnalysisFees & Costs
When it comes to fees and costs, users report criticism comparatively often. According to reviews, the fees and spread are repeatedly described as high. Especially among price-conscious users, this area is therefore perceived rather critically in the user data.
Direct crypto trading: total costs of 0.6% including the spread for liquid cryptoassets such as Bitcoin and 0.7% for less liquid ones, each for customary order sizes; orders start at €1. Crypto ETNs: order fee of €5.90 per exchange order plus exchange fees, and ongoing product costs (TER) that vary by issuer. As of October 2026.
Usability & User Experience
Users mainly report a clear design and an intuitive app with BISON. According to reviews, the platform is often described as easy to use, user-friendly, and self-explanatory. Some users mention annoying notifications and report that verification does not always go smoothly.
Not enough reviews available.
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.
Not enough reviews available.
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.
Not enough reviews available.
Customer Support
When it comes to support, users report mixed experiences in the reviews, but overall rather critical ones. There is repeated mention of no support or long response times, which is why some users describe customer service as room for improvement.

Verdict
In our overall rating Flatex leads with 3.1 against 2.5 for BISON.
On disclosed fees you pay €5.50 less at Flatex per €1,000 purchase.
Neither provider reaches 4.0 out of 5 in our rating, so we do not give an unreserved recommendation here.
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.
For investors in Germany who want to hold crypto with the same broker as their shares and ETFs, flatex is a solid choice: according to flatex, liquid assets such as Bitcoin cost 0.6% in total including the spread, less liquid ones 0.7%, each for customary order sizes. The selection of 25 cryptoassets is small, though, there is no staking and no crypto savings plan, and coins can neither be transferred to your own wallet nor deposited from one. flatex does not withhold tax on crypto gains, because directly held crypto is not subject to Germany's flat-rate withholding tax. Clients without a registered address in Germany cannot use direct crypto trading at all and are left with crypto ETNs. If you want a wide choice of coins or your own wallet, a crypto exchange is the better fit.
