Study Examines Hidden Costs Across Five German Retail Bitcoin Platforms

An analysis conducted by cryptoticker.io on September 30, 2026, reviewed fee structures across five platforms serving German retail customers: justTRADE, finanzen.net ZERO, BISON, Kraken, and N26. The findings indicate that purchasing 100 euros of bitcoin never yields a full 100 euros worth of the asset, even on platforms advertising commission-free transactions. While visible execution charges leave between 98.50 euros and 100 euros, the spread embedded in quoted prices adds an additional cost that most platforms fail to specify upfront.

The report highlights that the total cost of buying bitcoin consists of two distinct components: stated order commissions and bid-ask spreads. Order commissions appear directly on transaction statements as fixed execution fees or percentages. In contrast, spreads are integrated directly into the purchase price rather than charged as formal fees, allowing brokers to market zero-commission trading while still embedding profit margins.

According to the review, only one of the five surveyed providers discloses enough pricing detail for customers to calculate their final bitcoin receipt in advance. Among the platforms studied, justTRADE listed the lowest disclosed commission at 0.125 percent, deducting 12.5 cents on a 100-euro order with a 25-euro minimum order size, though it applies an additional trading venue spread.
