Services and trading mechanics
Sections ↑BISON is the Boerse Stuttgart Group’s app and web service for buying and selling cryptocurrencies. EUWAX supplies trading, while a separate group company provides crypto custody. The service also has securities accounts, whose bank, eligibility rules and trading arrangements differ from the crypto account covered here.[2]
Crypto trading parameters
| Parameter | Published rule |
|---|---|
| Trading session | Crypto trading is available around the clock; this is spot ownership, without short selling. |
| Minimum order | €0.01. |
| Largest per-trade limits | BTC, ETH, XRP and SOL: €500,000; ADA and DOGE: €250,000. |
| Other assets | Generally €100,000; a specified group of smaller assets has a €10,000 ceiling. The displayed asset limit governs. |
| Daily activity | No fixed count of daily trades; liquidity and security controls can alter executable size. |
Orders and reserved balances
| Instruction | How it works | Control |
|---|---|---|
| Limit | Maximum buy price or minimum sell price. | Price-limited requests expire after 90 days. |
| Stop | Buy above a trigger or sell below one. | A trigger does not remove execution and liquidity constraints. |
| Open request | Expected consideration is reserved. | Cancel before execution to release it; editing means cancel and replace. |
Savings plans debit the BISON euro settlement balance weekly, monthly or quarterly. Weekly plans permit a chosen weekday; monthly and quarterly plans use the first or fifteenth. A plan can be paused or terminated, and several plans can coexist. Insufficient funds can cause an occurrence to be skipped while the plan remains active, so closing the app or missing one payment does not stop later purchases. A bank standing order used to replenish the balance is a separate instruction.[6]
Staking availability
| Asset | Minimum | Who can use it |
|---|---|---|
| Ethereum | 0.005 ETH | Verified customers resident in Germany. |
| Solana | 0.1 SOL | German residence remains a continuing condition. |
| Staked balance | Not freely tradable | Moving abroad ends eligibility; exit requires the unstaking process. |
For a first purchase, staking activation can take up to two days for ETH or four for SOL. Rewards are credited weekly. Unstaking requires the underlying network’s release process, which can take days or weeks; the app shows progress. Neither BISON nor the customer can accelerate the network queue. BISON states that its staking service falls outside MiCA’s regulated service protections.[11]
Pricing and worked cost examples
Sections ↑Published crypto charges
| Cost component | Published basis |
|---|---|
| BTC and ETH spread | Average proportional spread of 1.25% when buying or selling. |
| Other crypto spread | Average 1.75%; market conditions and order size can change it. |
| Account and custody | No separate account or crypto custody charge. |
| Standard transfers | BISON charges no euro SEPA or crypto deposit/withdrawal fee; external providers may charge. |
| Staking | 27% of network rewards for ETH and SOL. |
The trading contract uses separate EUWAX buying and selling prices. A sale immediately after a purchase therefore receives the lower bid, even if the market has not moved. The following illustration uses invented executable quotes and assumes they remain unchanged; it does not represent a current BTC price or a guaranteed spread.[8]
Hypothetical unchanged-quote round trip
| Input or calculation | Result |
|---|---|
| Purchase budget / ask | €1,000 / €50,625 per BTC = 0.0197530864 BTC. |
| Immediate sale at invented bid | 0.0197530864 BTC × €49,375 = €975.31. |
| Cost before other effects | €24.69, or approximately 2.4691% of the starting euros. |
Card, Apple Pay and Google Pay funding adds 2.49% of the transaction amount. On a hypothetical €1,000 funding transaction that component is €24.90, before any cost of a later crypto trade. Eligibility requires at least three months of verification and an earlier euro deposit. The published range is €50–€10,000, with a €10,000 monthly cap. Visa and Mastercard require 3-D Secure; only two saved cards can be added within six months.[9]
A hypothetical gross staking reward of 0.01 ETH yields a 0.0027 ETH commission and 0.0073 ETH after that commission. This calculation applies the published 27% share to a given reward; it does not forecast the network reward, annual return or euro value.[7]
Funding, withdrawal routes and transfer checks
Sections ↑Euro payment routes
| Route | Requirements | Timing and limits |
|---|---|---|
| SEPA deposit | Euros from an account in the customer’s own name; use the current personal IBAN. No SWIFT, PayPal or third-party funding. | Ordinary transfers generally take 1–3 business days; instant SEPA can arrive within seconds.Source 14 |
| Published deposit limits | New customers: €20,000 per transfer / €200,000 monthly. Existing customers: €50,000 / €300,000. | Larger intended transfers require support review.Source 14 |
| Euro payout | Only unreserved euros, to the verified reference account established through an incoming deposit. | Normally 1–3 banking days; large payouts can receive additional checks.Source 15 |
Crypto deposits must come from wallets beneficially owned by the customer. A tradable asset is not necessarily enabled for deposits. Match the exact asset and network, and include required destination tags or memos such as those used for XRP, XLM and HBAR. Confirmation and source-of-funds checks can postpone crediting; sending an unsupported token to a familiar-looking address is not a supported deposit route.[16]
Selected published transfer minimums
| Asset and network | Minimum deposit | Minimum withdrawal | Address limitation |
|---|---|---|---|
| BTC on Bitcoin | 0.00005 BTC | 0.001 BTC | 1, 3 and bc1q addresses supported both ways; bc1p is deposit-only. |
| ETH on Ethereum mainnet | 0.000009 ETH | 0.01 ETH | Do not substitute an Ethereum layer-2 network. |
| SOL on Solana | 0.0002667 SOL | 0.1 SOL | Use the supported Solana route. |
Purchased crypto has a separate 24-hour withdrawal hold. Outbound requests require password, SMS and email confirmation. BISON permits cancellation within the first hour or while the request remains pending; after final processing the transfer cannot be reversed. Contact support if a withdrawal is still pending after 48 hours. A security setting can disable crypto withdrawals; re-enabling requires support and may take several business days. Transfers to another person’s wallet or a service provider’s wallet are prohibited; the destination must belong to the customer.[17]
BISON’s wallet-verification procedure can require a Satoshi test or digital signature once cumulative transfers involving a self-hosted wallet reach €1,000. A test approval lasts six months for the verified address; a changed address needs a fresh check. The test amount must arrive within three hours, and the sender bears its network cost. Requested beneficiary or platform details must also match the real transfer.[19]
Custody, bank balances and account security
Sections ↑Boerse Stuttgart Digital Custody GmbH holds crypto for customers through fiduciary custody. Customer assets may be pooled together, while remaining separate from the firm’s own assets; individual ownership is recorded in the custody relationship. The agreement also addresses third-party custody arrangements. Its liability provision for attributable crypto loss is tied to the asset’s market value at the time of loss, rather than protection against ordinary price falls.[13]
Different protections cover different assets
| Balance or activity | Published protection | Boundary |
|---|---|---|
| Euro bank balance | Statutory protection generally up to €100,000 per depositor per bank. | Solaris or Deutsche Bank holds crypto-account euros; crypto itself is outside deposit insurance.Source 21 |
| Trust account | EUWAX holds the bank balance for customers, separately from its own funds. | Other eligible deposits at the same bank share the protection ceiling; the BISON IBAN is not a general payment account.Source 22 |
| ETH staking | Munich Re-backed cover addresses specified slashing events, including operator failures. | The inspected description supplies no customer monetary cap and does not establish price-loss cover.Source 12 |
The Deutsche Bank arrangement is a trust omnibus account, rather than a separate personal bank account opened directly with that bank. BISON may ask the customer to reconfirm an intention to trade. If that confirmation is not supplied, idle euros can be returned to the reference account; funds can subsequently be deposited again. This is a balance-handling procedure, and the description does not specify a fixed inactivity-fee schedule.[20]
Device and recovery controls
| Control | Practical effect |
|---|---|
| Secure Session | A desktop crypto withdrawal needs approval from a trusted mobile device. A session lasts 20 minutes; extension or restart is mobile-controlled.Source 23 |
| Lost trusted device | Reset through an available trusted device, or contact support if none remains. Web access alone does not replace the approval device.Source 23 |
| SMS authentication | New devices and sensitive actions trigger checks; recognition can reset after 90 days, cookie changes, browser updates or private browsing.Source 24 |
| Lost phone number | Support requires identity evidence and proof of the replacement number. Email changes can require verification of both addresses and a callback.Source 25 |
Eligibility and verification
Sections ↑The crypto account is for private individuals aged at least 18. BISON excludes company, joint, third-party and multiple accounts, and requires no US tax liability. The customer must provide tax identifiers for all applicable tax residencies. Approved nationality and residence are separate checks. Access to securities requires additional German residence, nationality, tax and telephone conditions, so crypto eligibility should not be reused as a securities eligibility decision.[27]
BISON describes active provision in Germany, Austria and Switzerland. It also describes registration by other EEA citizens on their own initiative, subject to the supported-country rules. This distinction is narrower than assuming every EEA resident receives an identical marketed service or every nationality is accepted.[28]
Identity verification uses IDnow video identification or the supported German electronic-ID route. A passport or foreign identity document can require recent proof of residence, generally no older than six months. Video verification needs working camera and microphone access; the electronic-ID route needs the enabled identity-card function and compatible device. Verification and a successful deposit precede full account use.[29]
Support, disruption and leaving the service
Sections ↑BISON provides its Help Centre and contact form in German and English. Its BEA virtual support assistant can answer routine questions and collect details outside staffed hours. The published description gives it a support role; it does not establish authority to place trades, approve withdrawals or override identity checks.[2]
During extreme volatility trading may pause, and concentrated limit requests at the same price can be rejected. For a disputed order, BISON asks for the date, time, coin and description through the contact form. The inspected order guide offers no guaranteed emergency telephone execution route.[5]
Formal complaints are free and can be submitted using the complaint route or by post to EUWAX in Stuttgart. BISON targets a response within 15 business days; exceptional cases can extend to 35 with an interim explanation. Its procedure identifies the German Federal Universal Conciliation Body in Kehl as an external route, while access to courts remains available.[30]
To close the account, first remove all euro and crypto balances. The web interface can sell residual amounts that the mobile app cannot handle. Download reports before cancellation, because account access and the associated partner relationships end with closure. Simply ceasing to use the app is different from this explicit closing process.[26]
Legal entities and regulatory scope
Sections ↑Current primary register entries
| Entity | Identifier and basis | Recorded crypto services |
|---|---|---|
| EUWAX Aktiengesellschaft | BaFin ID 20000020; BAK 109154. Entry uses MiCA Article 59(1)(b), the notified financial-institution route. | Crypto/funds and crypto/crypto exchange from 1 April 2025; execution from 21 November 2025.Source 35 |
| Boerse Stuttgart Digital Custody GmbH | BaFin ID 10157207; BAK 157207. Article 59(1)(a) authorisation. | Custody/administration and transfer services from 17 January 2025.Source 36 |
Company, scale and related platforms
Sections ↑The website imprint identifies EUWAX Aktiengesellschaft, also styled EUWAX AG, at Börsenstraße 4, 70174 Stuttgart, registered in Stuttgart under HRB 19972. BISON is the product brand; it is not a separate legal counterparty replacing EUWAX.[3]
The homepage displayed more than 1,050,000 users when checked on 20 October 2026. Although another homepage passage calls them active users, it supplies no measurement window or activity definition. The figure therefore records BISON’s stated user reach, not independently verified monthly active traders or trading volume.[1]
BSDEX is a related Boerse Stuttgart platform with a separate account. Its FAQ explicitly says that a BISON login does not work there. The two products should therefore not be merged into one set of fees, order controls or account permissions.[37]

Reports, incentives and account tools
Sections ↑BISON’s Info Report is designed around German tax reporting and uses FIFO for realised results and holding periods. Externally transferred holdings can be excluded from automatic gain calculations, leaving the customer to reconstruct acquisition history. The report is available through the account’s document area; custody statements are also available, including historical-date requests back to 1 January 2025. These records support reconciliation but do not settle every customer’s tax treatment.[31]
Transaction-history exports use a selected period and arrive as CSV in the postbox. They cover purchases, sales, transfers and rewards. A zero crypto-fee field reflects the embedded spread, not zero economic trading cost. Referral or cashback credits can appear as deposits, and external wallet addresses are omitted from the CSV; use transaction details and outside records when those fields matter.[32]
