Verdict
In our overall rating Smartbroker+ leads with 4.4 against 4.0 for 21bitcoin.
On a €1,000 purchase you pay €1.10 less at 21bitcoin.
For most investors Smartbroker+ is therefore the better choice.
21bitcoin has established itself as an Austrian Bitcoin app across German-speaking Europe, valued above all for a transparent fee structure starting at 0.79%. The provider is licensed by Austria's Financial Market Authority (FMA) as a virtual asset service provider and deals exclusively in Bitcoin. Users single out the automatic transfer to a personal wallet above defined thresholds as a genuinely useful security feature.
The savings-plan approach is refreshingly uncomplicated: standing orders are invested in Bitcoin as soon as the money arrives, and the flat wallet-transfer fee of 0.00001 BTC is widely seen as fair. For investors in Austria, Germany and Switzerland looking for an FMA-regulated alternative to the Swiss Bitcoin apps, 21bitcoin reads as a solid option. Total costs of €7.90 on a €1,000 trade sit in the middle of the field.
Because Bitcoin is the only asset on offer, 21bitcoin is not aimed at investors who want a broad crypto portfolio – a limitation some users do point out. The absence of two-factor authentication in the app and the €15 minimum order also leave room for improvement. That makes 21bitcoin a good fit for Bitcoin-focused investors in German-speaking Europe who care about cost transparency, automatic wallet transfers and Austrian regulation.
Smartbroker+ is perceived in the DACH region as a multi-asset broker that combines cryptocurrencies with stocks, ETFs, and derivatives on one platform. With 25 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.
