BISON vs Flatex Comparison

Editorial assessment, November 2026: We have downgraded BISON to 1.9 out of 5 and do not recommend it. The deciding factor is cost. According to BISON's fee page (accessed 8 November 2026), the proportional spread on Bitcoin and Ethereum averages 1.25 percent per purchase or sale, and 1.75 percent on all other cryptocurrencies. Buying Bitcoin and selling it later therefore costs around 2.5 percent, and around 3.5 percent for other coins. Deposits by credit card, Apple Pay or Google Pay cost an extra 2.49 percent, and BISON keeps 27 percent of staking rewards on Ethereum and Solana. MiCA-licensed exchanges in our exchange comparison charge from 0.2 percent for the same purchase. The authorisation of EUWAX AG and Boerse Stuttgart Digital Custody GmbH in the ESMA register does not change this calculation.

BISON is the crypto app of Börse Stuttgart and is perceived in the DACH region as a provider with a traditional capital markets background. The provider is EUWAX AG, a Börse Stuttgart company supervised by BaFin that has notified BaFin of its crypto services under MiCA. Crypto custody is handled by Boerse Stuttgart Digital Custody GmbH, which has held a MiCA authorisation from BaFin since January 2025. Euro balances are held at Solaris SE and Deutsche Bank and are covered by statutory deposit protection up to EUR 100,000 per investor and bank. According to BISON, 69 cryptocurrencies are tradable, plus stocks and ETFs, and the app has more than 1.06 million users.

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. According to BISON, staking of Ethereum and Solana is currently not regulated under MiCA. Deposits are possible via SEPA, instant bank transfer, and credit card.

Costs sit in the spread, which according to BISON averages 1.25 % on Bitcoin and Ethereum and 1.75 % on all other cryptocurrencies, the upper range among the brokers compared. 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. Since April 2025 the bank has been notified to BaFin under MiCA for executing crypto orders, and its custodian Tangany has held a MiCA authorisation since August 2025. In France, the Netherlands and Spain the same bank has offered direct crypto trading under the DEGIRO brand since September 2025. If you prefer securities, more than 55 crypto ETNs can be bought through a savings plan from €1 with no order commission. If you want a wide choice of coins or your own wallet, a crypto exchange is the better fit.
