21bitcoinOur Opinion

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.

finanzen.net ZEROOur Opinion

finanzen.net ZERO benefits in the DACH region from the strong brand recognition of the financial portal finanzen.net and positions itself as a neobroker without explicit order fees. With 33 tradable cryptocurrencies, the broker offers a comparatively broad coin selection among German neobrokers. Crypto custody is handled by Tangany GmbH, which is licensed by BaFin, and is valued by security-conscious investors.

Particularly noteworthy are the savings plans starting at 0.01 €, which represent the lowest entry amount in the comparison of German brokers. The dedicated TAN app is considered a solid security feature. For investors who want to manage crypto alongside stocks and ETFs on one platform, finanzen.net ZERO is seen as an accessible option.

Despite the advertised 0 % trading fees, spreads lead to total costs of around 24 € per 1,000 € trade, which is considered room for improvement in the broker comparison. A wallet transfer is also not possible, and deposits are limited to SEPA transfers — both are occasionally criticized by users. finanzen.net ZERO is therefore especially suitable for investors who prefer a well-known German brand with BaFin-regulated custody and value particularly low minimum savings plan amounts.
