Signing up to a crypto exchange takes a minute, and then the platform asks for your passport, a selfie and proof of address. Many people pause right there. What KYC is, and why you can no longer buy bitcoin anonymously on a major platform, is worth going through step by step, with the actual requirements of the exchanges, real processing times and the limits that apply to anyone who would rather skip verification.
The rules and figures below come from the official help sections of Binance, Bybit and Kraken, and from the texts of the European regulations, as of 8 October 2026. Platforms change limits and document lists regularly, so before registering it is worth opening the current verification page on the specific exchange's site.
KYC is easiest to explain through a banking analogy. The abbreviation stands for Know Your Customer. It describes the set of procedures a financial company uses to establish a client's identity and assess the risk of working with them. A bank does this when opening an account, a broker when signing a contract, a crypto exchange at registration or before the first large withdrawal.
For the user it looks like uploading a document and recording a short video of their face. On the platform's side the chain is longer. First identification, meaning the collection of client data. Then verification, meaning a check that the document is genuine and belongs to this particular person. After that comes risk scoring and ongoing transaction monitoring, where the system compares account behaviour against the declared client profile.
The idea came from banking compliance and anti-money laundering regulation (AML, Anti-Money Laundering). The international standard is set by FATF, the Financial Action Task Force. Its recommendations are not law in themselves, but countries write them into national legislation, and supervisors later hold firms to account for following them.
It helps to separate four related concepts that often get mixed up.
For cryptocurrency the consequence is simple. A centralised exchange in a well-regulated jurisdiction has to know whose account it is servicing, and has to attach party data to transfers. Hence the document requirement.
The main reason sits with licensing. Large platforms have long operated under supervision and cannot afford anonymous clients. Binance made verification mandatory for all users back in 2021, and the exchange's help centre says the same today. A new user needs the Verified level, otherwise deposits and trading are unavailable, while older unverified accounts are switched to withdraw-only mode. A step-by-step walkthrough of registration and the platform's interface is in the guide How to trade on Binance: complete guide 2026. Bybit words it similarly and requires at least the Standard level for all of its products and services.
The second reason is practical. Fiat rails, meaning bank cards, SEPA and local payment systems, are run by banks and payment providers with compliance requirements of their own. Without a verified client an exchange simply cannot push a transfer in hryvnia, euro or dollar.
The third reason concerns the account itself. A verified account is easier to recover if access is lost, and harder to hijack by someone posing as support. Exchanges also screen clients against sanctions lists, which protects the platform from fines and protects a legitimate user from being frozen through a chain of counterparties.
The fourth consideration looks ahead. In the European Union, Regulation (EU) 2024/1624, known as the AMLR, applies from 10 July 2027. Its Article 79 prohibits servicing anonymous accounts, crypto accounts included, and handling instruments that obscure transaction data, for example Monero and Zcash. The EU crypto services market is already licensed under MiCA, with companies holding CASP status as crypto-asset service providers. Anonymous setups have a limited runway, and that is worth weighing when choosing a platform for years ahead.
In Ukraine the legal regime is still in transition. The law "On virtual assets" was passed in 2022 but never entered into force, because the matching tax code amendments were never adopted. Bill No. 10225-д, which is meant to replace that framework and introduce licensing for platforms, passed its first reading in September 2025 and is being prepared for the second. Until it is adopted, Ukrainian users deal with foreign exchanges under the rules of the jurisdictions where those exchanges are registered.
The process is nearly identical across the major platforms. The user opens the verification section in account settings, selects country of residence and document issuing country, uploads the document itself, passes a liveness check (a short real-time sequence of frames showing the face) and confirms personal details. The application is then processed automatically, with disputed cases going to manual review.
One detail saves hours. The data in the form has to match the document character for character, including the transliteration of the name. Binance warns that once confirmed, you cannot change it yourself, and any later correction runs through a separate data update procedure.
The basic set is similar everywhere, what differs is the depth of the check.
Proof of address is usually a utility bill, a bank statement, a tax document, a certificate from a government body or a tenancy agreement running longer than six months. Bybit accepts such a document only if it was issued no more than three months before submission. The exchange separately lists what will not do, and the list is not obvious. It includes mobile phone statements, insurance and medical documents, bank transaction slips and handwritten receipts. A domestic passport and student, work or travel visas are not accepted as identity documents either. A walkthrough of the platform's own interface is in the guide How to trade on Bybit: complete guide for beginners 2026.
One more Bybit requirement is a frequent cause of rejection. The exchange accepts only photographs of the physical original document and rejects scans and electronic copies. And exactly one verified account is allowed per person.
Not everyone needs to raise their level in advance. If the task is limited to spot trading and withdrawals in crypto, the base tier is usually enough. Proof of address and source of funds come into play where fiat is connected, amounts grow, or access opens to particular products. The logic is the same everywhere, and the higher the potential risk of an operation, the deeper the check.
The platforms publish their own benchmarks. Bybit cites roughly fifteen minutes in a normal case and a ceiling of 48 hours for a complex check, and if that is exceeded it suggests opening a support case. Binance states that documents are usually reviewed within 48 hours, though in some cases it takes longer. Kraken says it most often finishes inside 30 minutes, with manual review stretching that out. Kraken's help page dated 6 October 2026 carries a separate notice about delays in processing new accounts and a request not to submit repeat applications, which shows well how these benchmarks drift under load. The general order of working with the platform is covered in the guide How to trade on Kraken: the complete guide 2026.
The practical takeaway is simple. Get verification done before the money is needed, not at the moment an urgent withdrawal comes up.
Bybit publishes a list of typical rejection reasons, and it repeats almost word for word on other platforms.
The last point deserves a careful read. Bybit determines country restrictions by the trader's nationality, not by their current place of residence. Relocating does not by itself open access.
Platforms where you can trade with no documents at all are getting fewer every year. The large centralised exchanges have closed that route. Where an account is formally created with just an email, the platform reserves the right to request documents at any moment, and the request usually arrives right before a withdrawal.
Two options remain. First, second-tier centralised exchanges that leave an unverified account a small withdrawal allowance. Second, decentralised platforms where trading runs straight from the user's wallet and there is no account as such, for example Uniswap, Hyperliquid or dYdX.
The choice between them rarely comes down to anonymity alone, so a point-by-point comparison helps.
The first limitation comes down to money. Without verification the entire fiat loop is closed. Buying crypto with a card, withdrawing profit to a bank account or using P2P with platform escrow is not possible, and only crypto-to-crypto exchange remains.
The second concerns the size of the account. Platforms revise limits for unverified accounts regularly, usually tightening them, so relying on a figure from someone else's six-month-old article makes little sense. Check the exchange's own limits page on the day of the operation.
The third, and the most unpleasant, is a funds freeze triggered by internal risk control. In the summer of 2025 a trader known as White Whale publicly claimed that MEXC had locked around $3.1 million on his account without any breach of the terms of service, and then offered to confirm his identity at an in-person meeting in Malaysia, even though no such procedure appears in the exchange's terms. The platform responded that restrictions are not applied arbitrarily and stem from AML obligations. These are the positions of two sides in a public dispute rather than established fact, but the situation shows the nature of the risk. While assets sit on a centralised platform, access to them is decided by its compliance team, and the absence of verification does not strengthen the client's negotiating position.
The fourth limitation applies to decentralised platforms. Documents genuinely are not needed there, but in exchange the user picks up a different set of problems. There is no support desk to restore access. An error in an address or a lost key is irreversible. Network fees come on top of trading fees. In a thin market slippage becomes noticeable, meaning the gap between the expected and the actual execution price. Many protocols' web interfaces restrict access by country, and the anonymity itself is conditional, because the blockchain is public and analytics services link addresses to one another.
The fifth concerns workarounds. Ready-made verified accounts sold in topic chats breach the rules of every large platform. Binance states plainly that an account cannot be transferred to another person and that you cannot substitute someone else's ID for your own. The risk here is twofold. The exchange closes such an account at the first unscheduled review, and the seller keeps access to the email and documents the account was opened under.
One scenario is worth spelling out, the one where the "I will manage without verification" strategy breaks. A trader works for a year on a platform with a small daily withdrawal cap, the balance gradually grows, and at some point the accumulated amount can no longer go out in a single payment. The exchange offers to raise the limit through verification, and the documents are submitted not calmly but under pressure, with the money effectively locked. If a mismatch with the real place of residence or nationality then surfaces in the form, the review drags on. Verification completed in advance never creates that situation.
The main argument against verification is practical rather than ideological. A passport copy and a selfie handed to a platform live on there, and a leak of that set is more dangerous than a leaked password. A password changes in a minute, a passport number does not.
The example is not hypothetical. In May 2025 Coinbase disclosed that attackers had bribed some staff at an outsourced support operation and obtained access to customer data. The leak covered names, addresses, phone numbers, email, the last four digits of social security numbers, masked bank details, transaction history and images of government-issued documents. According to the notification filed with the Office of the Maine Attorney General, 69,461 individuals were affected. The attackers demanded $20 million to stay quiet, the company refused to pay, and it put its own remediation costs at $180–400 million. The exchange's systems were not breached, the data was carried out by people with legitimate access.
One more point rarely gets attention. The data does not disappear after the check. Anti-money laundering regulation obliges companies to retain client and transaction records for a set period after an account is closed, and that usually means several years. You cannot have an uploaded passport withdrawn on request. The decision to verify is made once and holds for a long time, which is why it is worth choosing platforms with a clear jurisdiction and licence rather than the first one that comes up.
The working conclusion follows from that. A user cannot rule out a leak on the platform's side, but can reduce the damage.

There is a separate question about trading software that comes up for almost everyone. A terminal for working with the order book, the tape and clusters does not ask for documents, because it connects to the exchange not as a client but through an API key for an account that already exists. Secret Terminal is built this way and stores user data locally on the computer, without sending it to external servers. A key carries a set of permissions, and for analysis and trading it is enough to allow trading operations while leaving withdrawal permission off. If the exchange supports binding a key to an IP address, that is worth enabling. Then even a compromised key will not let anyone move assets off the account.
Creating such a key and connecting an exchange is shown in a free lesson on the Secret Terminal YouTube channel.
It is a check on a client's identity before a platform starts servicing them. The exchange asks for a document and a photo of the face, matches the details and decides whether to open full access. The procedure came from banking and works on the same principles at crypto exchanges.
Technically yes, but the choice of platforms has narrowed. On Binance a new account without the Verified level gets neither deposits nor trading. Bybit requires at least the Standard level for its products and services. What remains is decentralised protocols and a few centralised exchanges with tight limits, and in both cases the limitations described above apply.
Usually from fifteen minutes to two days. Bybit cites a benchmark of about fifteen minutes and a ceiling of 48 hours, Binance fits within 48 hours, Kraken states under 30 minutes for an automated check. Manual review of a disputed application stretches the timeline, and during surges in new registrations the platforms warn about delays themselves.
A passport, ID card or driving licence showing a photo, date of birth and document number. At advanced levels proof of address is added, for example a utility bill or a bank statement no older than three months. Bybit specifically notes that it accepts photographs of physical originals rather than scans and screenshots.
Check the reason in your account and submit again with it fixed. Most often it comes down to image quality, a mismatch between the form and the document, or an already verified account existing for the same person. If the reason is unclear, contacting support with the application number helps.
Yes, it is part of enhanced due diligence. The request usually arrives with large amounts, unusual operations or an internal rule being triggered. A bank statement, a contract, documents on the sale of property or an income certificate work as confirmation. Ignoring the request is a bad idea, as account operations will be restricted until a reply arrives.
No. The terminal connects through an API key to an account that already exists and does not ask for documents. But if the exchange account itself is unverified, the platform's limits and restrictions stay in force regardless of which interface the trading runs through.
What KYC is and why it is needed boils down to a trade. The user hands the platform data and in return gets fiat rails, workable limits and a defined procedure in case of a dispute. Verification is done once, and after that the time goes into what the whole thing was for, working the market. Secret Terminal connects over API to Binance, Bybit, OKX, WhiteBIT, Kraken and other platforms, brings the order book, the tape, clusters and charts into one workspace, and stores data locally on your computer. The free version for Windows and MacOS is available at secret-terminal.com.
