Verdict

In our overall rating Relai leads with 4.2 against 3.1 for Flatex.

On a €1,000 purchase you pay €2.00 less at Flatex.

For most investors Relai is therefore the better choice.

FlatexOur Opinion

For investors who want crypto exposure inside a conventional brokerage account alongside shares and ETFs – complete with German tax reporting and a familiar interface – flatex is a solid choice. If you want to own real coins and withdraw them to your own wallet, you need an actual crypto exchange instead.

RelaiOur Opinion

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. With a VASP license in Switzerland and an ongoing MiCAR license application, Relai is 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. Fees of 0.9 % are in the mid-range of the brokers compared.

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 Swiss regulation.
