Tagesgeld-Konto.net Tagesgeld-Konto.net — Ein mächtiger Strom beginnt oft mit einer beständigen Quelle, doch erst die intelligente Kanalisierung der gewaltigen. 
With the granting of the official cryptocurrency custody license by the Federal Financial Supervisory Authority (BaFin) to blocknox GmbH, the Stuttgart Stock Exchange has created a regulatory turning point in European trading with digital assets. Instead of forcing investors into the unregulated offshore environment, the Bison App operates as a fully regulated interface in Germany between the traditional fiat system and the crypto market. The trading process does not take place through an anonymous order book, but is handled by EUWAX AG – a wholly-owned subsidiary of the Stuttgart Stock Exchange – as a liquidity provider and trading partner. This architecture eliminates the counterparty risk that exists with many foreign crypto exchanges due to insufficient deposit protection and lack of regulatory oversight.
While we at Tagesgeld-Konto.net always emphasize the fundamental importance of the deposit insurance fund for traditional cash positions, the crypto sector requires a completely different risk assessment regarding custody and market integrity. The choice of a specific trading venue not only determines transaction costs but, above all, the legal security of the deposited assets in the event of a market disruption.
The Regulatory Architecture: Trading Under the Umbrella of the Stuttgart Stock Exchange
The legal and technical structure of the platform fundamentally differs from traditional crypto exchanges. Investors do not trade directly with each other (peer-to-peer order book), but enter into a bilateral trading transaction with EUWAX AG. EUWAX AG continuously provides buy and sell quotes and ensures the execution of customer orders. This brokerage model guarantees immediate execution certainty at the displayed prices, without the risk of partial order execution due to insufficient liquidity in the order book.
Trustee Custody by blocknox GmbH
A central weakness of many trading platforms is the mixing of customer funds, equity, and crypto holdings. The Stuttgart platform strictly separates these levels. The acquired cryptocurrencies are held in trust by blocknox GmbH. This company acts as a dedicated crypto custodian and maintains the holdings in a multi-tiered security system. A large portion of the assets is secured in so-called cold wallets – that is, storage media physically disconnected from the internet – to minimize the risk of cyberattacks and hacks. Custody is free for the end customer and is already included in the spread costs of trading.
Fee Structure and Spread Mechanics in Detail
The monetization of the platform does not occur through direct order commissions (commission-free trading), but through the difference between the buying and selling price – the so-called spread. This is a crucial factor for return calculation, especially in short-term trading strategies (day trading) or the use of savings plans.
The Target Spread and Market Volatility
The broker does not charge fixed order fees, custody fees, or deposit and withdrawal costs. Instead, a variable spread is applied, which is oriented towards a target value of 1.25 percent. In phases of extremely high market volatility or with illiquid altcoins, this spread can dynamically increase, as EUWAX AG must hedge its own price risk when quoting prices. For the investor, this means: The displayed buy and sell prices already include all costs. There are no hidden surcharges (slippage), as the trading price is guaranteed at the time of order confirmation.
| Comparison Criterion | Stuttgart Stock Exchange Platform | Offshore Crypto Exchanges | Traditional Neobrokers |
|---|---|---|---|
| Fee Model | Spread-based (approx. 1.25%) | Maker/Taker Fee (approx. 0.1% – 0.5%) | Fixed external cost flat rate + spread |
| Asset Transfer (Withdrawal) | Free to own wallet | Network fees apply | Usually not possible (closed system) |
| Regulation & Custody | BaFin (Germany) | Often unregulated / third countries | BaFin (Germany) |
| Tax Reporting | Automated info report (FIFO) | External tools required (API) | Integrated tax deduction (KapESt) does not apply to real cryptos |
Step-by-Step Guide: From Onboarding to First Trade
The integration of this trading platform into the private portfolio requires a structured process that complies with the strict requirements of the Money Laundering Act (GwG). Those who install the Bison App on their device go through a standardized KYC process (Know Your Customer), which forms the basis for opening the fiat account.
KYC Process and Capitalization of the Settlement Account
The referenced fiat balance (Euro) is not held at the Stuttgart Stock Exchange itself, but at Solarisbank AG in Berlin. This has the significant advantage that the Euro deposits are subject to statutory deposit insurance (up to 100,000 Euros). The verification process is seamlessly conducted via the VideoIdent procedure from IDnow. After successful verification, the investor receives an individual IBAN. The capitalization of the account is done traditionally via SEPA transfer. Only when the Euro balance is credited is the liquidity released for trading – margin trading on credit is systemically excluded, which drastically increases investor protection.
Order Types and Strategic Market Entry
A professional crypto portfolio requires precise timing. The platform offers, in addition to the classic market order (execution at the next available price), limit orders as well as stop-buy and stop-loss orders. By placing a limit order, investors can fix the entry price and protect themselves against short-term price spikes. The trade is only executed when the price of the underlying asset (for example, Bitcoin or Ethereum) reaches the defined target value, allowing the investor to maintain control over the effective entry price.
Tax Documentation for German Crypto Investors
The taxation of digital assets often poses massive administrative challenges for private investors. Unlike traditional stocks or ETFs, where in Germany the flat tax (capital gains tax) of 25 percent plus solidarity surcharge is automatically deducted by the custodian bank, real cryptocurrencies are subject to different tax mechanisms.
Private Sales Transactions and the FIFO Method
Cryptocurrencies are classified as “other economic goods” under German tax law. Their trading falls under § 23 of the Income Tax Act (EStG) as a private sales transaction. Gains are completely tax-free if more than one year (365 days) elapses between acquisition and sale. For sales within this holding period, a tax-free allowance of 600 Euros per calendar year applies. If this limit is exceeded, the entire profit is subject to taxation at the personal income tax rate.
To simplify these complex calculations, the platform strictly applies the FIFO method (First-In-First-Out) in its documentation. The oldest holdings of a coin are considered to be sold first for tax purposes. The greatest added value for the investor is the annually generated info report. This document prepares all transactions of the year in compliance with tax regulations, lists tax-free as well as taxable gains, and can be directly passed on to the tax advisor or included as an attachment “SO” (Other Income) in the income tax return. This eliminates the need for expensive external tax tracking software.
Conclusion and Strategic Action Instructions
For investors who prefer the regulatory framework of a German exchange over the minimally cheaper but riskier trading on foreign platforms, this broker model offers an excellent foundation for crypto trading. To optimally utilize the platform’s structure for personal wealth building, the following operational steps should be implemented:
- Consistently use limit orders: Avoid unlimited market orders to protect yourself from sudden widening of the spread during volatile market phases. Instead, set hard price limits for buy and sell orders.
- Activate savings plan function to smooth volatility: Set up automated, fee-free savings plans (starting from small amounts) to benefit from the cost-average effect and minimize timing risk in the highly volatile crypto market.
- Extract tax report annually: Actively download the provided info report at the beginning of the new year and check your realized gains against the 600-euro exemption limit according to § 23 EStG before submitting your tax return.
- Check self-custody for long-term holdings: Utilize the option for free withdrawal of real cryptocurrencies. If you build significant holdings beyond the one-year holding period as “buy and hold” positions, transfer them to your own hardware wallet to gain absolute control over your private keys.
Note on financial risks: Cryptocurrencies are highly speculative asset classes and are subject to extreme price fluctuations up to the risk of total loss. The information provided here does not constitute individual investment advice. The tax treatment depends on personal circumstances and may be subject to future changes. Check the current spread conditions of the provider before each transaction.
