Verdict
In our overall rating Flatex leads with 3.1 against 2.9 for BSDEX.
On disclosed fees you pay €3.50 less at BSDEX per €1,000 purchase.
Neither provider reaches 4.0 out of 5 in our rating, so we do not give an unreserved recommendation here.
BSDEX is a regulated crypto trading venue of Börse Stuttgart. Custody is handled by Boerse Stuttgart Digital Custody GmbH under BaFin supervision, and withdrawals to your own wallet are free. That is solid, but compared with other platforms it is not enough for a good rating.
The offering is narrow: only 10 cryptocurrencies, no savings plan, no staking and SEPA bank transfer as the only payment method. Buying with a market order costs 0.35 %; the advertised 0.20 % applies to maker orders only. Two-factor authentication works via SMS only, authenticator apps are not supported. Users are lukewarm too: the app scores 1.5 stars on Google Play and 3.2 on Trustpilot, with reports of login problems, repeated logouts and issues after updates.
Our verdict: BSDEX suits investors who only want to hold Bitcoin and a few large coins through German exchange infrastructure. If you are looking for a regulated platform with a wider selection, savings plans or staking, Bitpanda or Coinbase are the better choice.
For investors in Germany who want to hold crypto with the same broker as their shares and ETFs, flatex is a solid choice: according to flatex, liquid assets such as Bitcoin cost 0.6% in total including the spread, less liquid ones 0.7%, each for customary order sizes. The selection of 25 cryptoassets is small, though, there is no staking and no crypto savings plan, and coins can neither be transferred to your own wallet nor deposited from one. flatex does not withhold tax on crypto gains, because directly held crypto is not subject to Germany's flat-rate withholding tax. Clients without a registered address in Germany cannot use direct crypto trading at all and are left with crypto ETNs. If you want a wide choice of coins or your own wallet, a crypto exchange is the better fit.
