Coinfinity: Bitcoin dealing, euro payments, savings plans and self-custody

Coinfinity buys from and sells directly to the customer. Retail execution centres on accepting a dealer quote. Bitcoin is the standard asset; another crypto-asset requires an individual agreement. Its broader regulatory permissions do not establish a live retail altcoin market.[2]

The ordinary minimum order is €21. Lightning purchases have a €10 minimum and €250 maximum, alongside account-specific verification and funding limits.[2]

When selling, the ten-minute timer concerns initiating the Bitcoin transaction. It does not require the network to finish confirming it within ten minutes. Select the intended wallet and a sensible network fee before starting; confirmation can take longer. This distinction matters when a wallet asks for additional signing approval or when network traffic is heavy.[7]

The cancellation help page says confirmed SEPA orders cannot be cancelled. Treat the confirmation screen as the point for checking amount and destination. Closing the app afterwards is not a cancellation instruction, and a later change in the market price does not give the purchase a new rate.[6]

At a €1,000 fee base, 1.5% is €15. A hypothetical purchase and sale each measured on a €1,000 base would incur €30 in service charges before mining costs, bank charges or changes in Bitcoin’s price. This is a comparison of fee amounts, not a projected round-trip investment return; the eventual sale base will normally differ.[4]

On a €21 order the €0.49 minimum replaces the smaller percentage charge. The floor cannot be discounted; dividing purchases into small orders can therefore raise effective costs.[2]

BlockReward gives an eligible referred customer a 21% reduction in the service fee for six months. The referrer can earn 21% of qualifying service fees, paid monthly by SEPA once at least €10 has accrued. Referrers need an active account and a completed purchase of at least €21; the referral must meet the pre-first-order conditions. This is a conditional referral payment and fee discount, rather than interest on Bitcoin or a general deposit bonus.[16]

An existing-account referee may qualify before their first order. However, the referrer receives no bonus if that account already existed or the code was generated after the referee registered. The fee discount cannot combine with other reductions.[2]

The Fees & Limits screen displays the customer’s actual fee schedule and remaining buying and selling allowances. It distinguishes the allowance before additional proof of funds from time-based limits. Its 48-hour window can reset once payment and Bitcoin settlement have completed; it should not be read as a universal two-day lock on every customer.[14]

A bank transfer is also an ownership check. Paying from somebody else’s account can prevent matching or acceptance even if the reference and amount are correct. The published purchase methods are euro bank rails, so a customer with a different bank-account currency should establish their bank’s conversion and charges before sending. Coinfinity’s payment guide does not offer a multi-currency cash account.[11]

The purchase delivery guide sends an email once Bitcoin has been dispatched. Distinguish bank receipt, dispatch and blockchain confirmation when tracing a delay: they are separate events. Save the order reference and payment confirmation so support can locate the transfer. Network settlement should not be judged only from the time the bank showed a debit.[12]

Sale proceeds go to an account bearing the customer’s name; third-party payouts are excluded. Coinfinity says it sends outgoing bank payments by SEPA Instant, but the receiving bank’s capabilities still affect arrival. A completed blockchain transfer and a visible bank credit are separate milestones, so allow for both when planning a cash requirement.[8]

The June 2026 retail risk notice says purchased Bitcoin is held in a wallet controlled solely by the customer. Once delivered, it is outside Coinfinity’s insolvency estate according to that disclosure; transactions still awaiting settlement may nevertheless be delayed or fail. Bitcoin itself has no statutory deposit-insurance or investor-compensation protection. Self-custody changes who controls the asset; it does not eliminate transaction or device risk.[30]

For external wallets, the policy requires adding the address or extended public key. Purchases above €999 and sales from external wallets require ownership confirmation; the guide says an extended public key is mandatory for sales. New wallets or addresses also require email-code approval. The in-app wallet handles the relevant confirmation automatically. Complete these steps before initiating a time-sensitive sale, rather than trying to prove control after sending.[13]

Two-factor authentication protects access to the Coinfinity account, while the recovery phrase controls the Bitcoin wallet. These are different credentials with different recovery consequences. The published 2FA instructions explain activation but do not establish a universal withdrawal-hold period after every password or device change; obtain the applicable recovery instructions if access is lost.[15]

The identification guide describes an Austrian target market and says applications from residents elsewhere may be possible through passive provision of services. That statement is not a comprehensive country-acceptance list. A prospective customer outside Austria should obtain confirmation of residence eligibility and the actual contracting terms before planning a transfer. Available identification routes include official photo ID with bank verification, an NFC-capable passport, or verification at the Graz office.[17]

Source-of-funds examples include payslips or a current tax assessment, securities-sale records linked to the receiving bank statement, and property-sale documentation. A narrative can help connect a complicated sequence of transactions. Proof of a current bank balance alone may not explain where the money originated; retain the records connecting the original source to the account making the purchase.[32]

The personal registration flow first activates the email address and then directs the user to dashboard verification. This makes it useful to distinguish an account that exists from one authorised for the intended transaction. Resolve any missing identity information before sending money, especially if a purchase depends on a near-term price or payment deadline.[9]

Support is available at [email protected], by telephone on +43 316 711 744 and through app chat. The published Graz front-office hours are Monday to Friday, 09:00–13:00 and 14:00–17:00; callbacks can be booked. Those office hours do not constitute a promise of continuous staffed dealing support simply because online buying and selling is available around the clock.[25]

The complaint procedure lists the FMA, the Austrian financial-services industry ombudsman and consumer conciliation as escalation contacts. Their inclusion does not establish that every dispute will produce compensation. Preserve the complaint, supporting documents and written reply, particularly where the disagreement concerns a confirmed quote, payment timing or the chosen wallet address.[24]

The FMA’s 19 December 2025 decision granted Coinfinity GmbH, FN 415803a, MiCAR authorisation under Article 63. The listed activities are custody and administration, exchange against money, exchange against other crypto-assets, advice and transfer services. Operating a crypto trading platform is not one of the activities listed in that notice. Its older virtual-currency registration ceased when the new authorisation was granted. This is a dated regulator decision, not a claim that every authorised activity is offered in the standard app.[27]

The regulatory history also includes a final €105,000 fine announced by the FMA on 6 October 2025. The authority identified shortcomings in enterprise risk analysis, employee training, and policies and procedures for customer due diligence on occasional transactions. It said the accelerated proceeding had ended and the penalty decision was final. This is a specific historical compliance finding; it should be considered alongside, and not confused with, the later authorisation decision.[28]

The legal operator is Coinfinity GmbH, registered as FN 415803a in Graz. Its imprint gives Griesgasse 10, 8020 Graz as the business address and names Raimund Ortner and Stefan Grill as management. Use that entity and the actual agreement when checking correspondence or payment instructions; the product names describe services within the business.[26]

Coinfinity dates its beginnings to 2014, when Max Tertinegg and Stefan Kliment opened the original Graz Bitcoin business. Its April 2024 anniversary account describes a local shop and over-the-counter purchases. That history helps explain the continuing emphasis on personal assistance and self-custody, but longevity alone is not evidence of present liquidity or audited trading volume.[29]

A 1 October 2026 announcement says Raimund Ortner succeeded Max Tertinegg in management, working alongside Stefan Grill. It assigns Ortner the client division and Grill internal operations; Tertinegg is to focus on artificial intelligence. A change in an executive’s work does not itself establish an AI trading mandate or a customer-facing autonomous dealing product.[35]

In February 2026 Coinfinity announced the acquisition of the physical bitcoin.wien business, describing advice and education plus planned integration of in-store buying and selling. The Vienna operation complements the digital service. The announcement should not be read as proof that every promised shop feature had already launched on that date.[34]

The Austrian withholding guide is expressly limited to Austrian tax residents. It requests acquisition dates and costs to calculate the relevant capital gain, distinguishes holdings acquired before 1 March 2021, and describes a 27.5% withholding rate for applicable newer holdings. If records are missing or implausible, its fallback assumes half the sale proceeds as acquisition cost. Preserve purchase and transfer records before moving Bitcoin between wallets; a wallet balance does not by itself establish tax cost.[31]

Coinfinity’s March 2026 DAC8 explanation says it collects tax residence and identification numbers and describes annual transaction reporting to Austrian authorities. That provider reporting does not replace the customer’s own records. A user changing residence or operating through a company should keep the account’s tax details current and check the reporting treatment for that specific situation.[19]

Account deletion is a user-requested app process: open Your Account, then Personal data, and select Delete Account. That instruction is separate from cancelling a bank standing order or securing a self-hosted wallet. The deletion help page does not establish that leaving an account idle automatically closes it, nor does it document a recurring inactivity charge.[33]

For recurring purchases, the user controls the amount and frequency at the bank. Cancelling the standing order stops future plan payments; a saved plan label is not a bank debit mandate. Match the payment reference to the intended plan so that a changed savings schedule does not become an unidentified transfer.[21]
