Conclusion — Strengths, limitations and suitable uses. Your workflow and the functions it requires are what matter.
In this direct comparison, 21bitcoin and BISON are two broker-style crypto exchanges with spread price logic — no maker/taker order book. Both are aimed at users who want to invest in crypto via app and recurring investment plan, without a Pro-CEX trading mask. Costs arise via the spread; a sensible comparison sums up the buy and sell sides. CASP license is documented for both; Proof of Reserves is missing from the catalog for both.
21bitcoin is an Austrian Bitcoin-only broker: only BTC/EUR, no multi-asset catalog. Lightning payout is documented; Staking is missing. Recurring investment plan from EUR 25; SEPA and card deposits, without SEPA Instant and PayPal. Tax data as CSV, not native for DE. If you only want to build Bitcoin, you will find a narrow product area. Profile: 21bitcoin.
BISON is the Stuttgart Stock Exchange's app with multi-asset spread buying, market, limit and stop orders. Recurring investment plan from EUR 0.01, staking, SEPA Instant and native tax report DE. Costs are within the documented spread - the Stuttgart context and BaFin reference describe the supervisory framework, but do not replace a condition check. Futures and Perps are missing; API and sub-accounts are not provided. Details: BISON.
No overall rating: Bitcoin-only with Lightning and narrow scope vs. multi-asset with stop orders and native DE tax report — the relative classification is derived from the catalog lines.
