Our 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.
