BISON vs Relai 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.

Relai has established itself in the DACH region as one of the best-known Bitcoin-only apps and is especially appreciated by the Bitcoin community. The Swiss company follows a consistent self-custody approach: Bitcoin is held directly in the in-app wallet, and transfers to external wallets, including hardware wallets, are possible. Customers in the EU are served by Relai EU SASU, which has held a MiCA authorisation from the French financial markets authority AMF since 23 October 2025 and, according to the ESMA register, may operate in all 27 member states via the EU passport; in Switzerland, Relai AG is a member of the self-regulatory organisation VQF. Relai is therefore considered to be on solid regulatory footing.

The savings plan functionality is particularly valued, enabling automatic Bitcoin purchases with direct transfer to your own wallet or a hardware wallet. For investors who see Bitcoin as a long-term store of value and place importance on self-custody, Relai is regarded as one of the most accessible solutions. The fee is 1 % per purchase, or 0.9 % with an invite code; the first monthly auto-invest plan up to €100 remains fee-free. Paying by credit card, Apple Pay or Google Pay adds 3.0 %.

Since only Bitcoin can be traded, Relai is not suitable for investors interested in altcoins, something occasionally criticized by some users. The minimum amount of 50 € and the setup of external wallet transfers are also seen as room for improvement. Relai is therefore especially suited to Bitcoin-focused investors who want to combine self-custody and automated saving with a regulated provider.
