Verdict
In our overall rating Smartbroker+ leads with 4.4 against 4.1 for BSDEX.
On disclosed fees you pay €5.50 less at BSDEX per €1,000 purchase.
For most investors Smartbroker+ is therefore the better choice.
BSDEX is valued as the official crypto trading venue of Börse Stuttgart and is considered one of the most trustworthy platforms in the German market. With custody licensed by BaFin through Boerse Stuttgart Digital Custody GmbH, trading fees of 0.35 % and free wallet withdrawals, the platform is viewed positively by security-conscious investors.
The selection of only 10 cryptocurrencies is clearly room for improvement compared with other exchanges. The absence of a savings plan, staking and alternative payment methods beyond SEPA is also occasionally criticized. The 2FA protection via SMS only instead of TOTP is likewise seen as needing improvement.
BSDEX is considered particularly suitable for investors who value a German, regulated infrastructure connected to Börse Stuttgart and want to focus on the main cryptocurrencies such as Bitcoin and Ethereum.
Smartbroker+ is perceived in the DACH region as a multi-asset broker that combines cryptocurrencies with stocks, ETFs, and derivatives on one platform. With 39 tradable cryptocurrencies and custody via the BaFin-licensed Tangany GmbH, the provider is considered to be on solid regulatory footing. Trading fees of 0.9 % for crypto are in the mid-range among German neobrokers.
The option to set up savings plans from as little as 0.01 € is appreciated, as it enables an especially accessible entry point. The platform is available via app and web and is aimed at investors who want to manage different asset classes centrally. For users who already invest in stocks and ETFs and want to add crypto as an additional component, Smartbroker+ is seen as a practical solution.
Wallet transfers to personal wallets are currently not possible, and staking features are not offered — both are occasionally criticized by users. The limited deposit methods, restricted to SEPA transfers, and the waiting time after registration are also considered to have room for improvement. Smartbroker+ is therefore particularly suitable for securities investors in the DACH region looking for a German broker with BaFin-regulated crypto custody and a broad product range.
