Buying or selling cryptocurrency through a P2P platform often involves transfers between individuals’ bank cards. For the user this may look like an ordinary exchange, but the bank sees only hryvnia movement: numerous incoming payments from different people, repeating amounts, rapid onward transfers, or activity that does not match the customer’s known financial profile.
In that situation the bank may suspend a specific transaction, temporarily restrict account use, or request explanations and documents. Completing a P2P trade does not automatically mean a legal violation. At the same time, having an order on a crypto exchange does not guarantee that the bank will treat every transfer as clear and documented.
The customer’s main task is not to hide the economic substance of the operations, but to show consistently where the cryptocurrency came from, to whom it was sold, how the P2P order links to a specific bank transfer, and why the volume of deals matches the customer’s income.
Why a bank may restrict an account after P2P trades
Under financial monitoring legislation, banks check customers, analyse their financial operations, and apply a risk-based approach. The decision therefore depends not only on the amount of a single payment, but also on overall account behaviour, the number of counterparties, payment purposes, the customer’s financial profile, and other risk factors.
The bank’s attention may be drawn by:
- regular incoming payments from a large number of unfamiliar persons;
- significant turnover without confirmed income at a matching level;
- rapid withdrawal or transfer of almost all received funds;
- splitting one amount into many similar payments;
- transfers whose economic substance cannot be established;
- a complaint from another customer, a fraud notice, or a counterparty linked to suspicious activity;
- using a personal card for systematic activity that resembles entrepreneurial activity.
Important: there is no universal “safe amount” that automatically excludes review. Even small transfers may be analysed together if their frequency or structure does not match the customer’s ordinary activity.
The legal framework for such measures is set by Law of Ukraine No. 361-IX, and the National Bank of Ukraine explains the general principles of bank work in this area on its page on financial monitoring.

What to do after a card or individual transaction is blocked
Act calmly and with documents. Attempts to urgently move funds between other banks, open new cards, or give contradictory explanations may only complicate the review.
- Clarify the nature of the restriction. Through the bank’s official chat, phone line, or branch, establish whether a specific payment was stopped, outgoing operations were limited, the payment instrument was blocked, or the bank is reviewing the business relationship as a whole.
- Ask for a list of required documents. Requirements differ across banks. It is better to obtain them in writing and record the ticket or reference number.
- Build a chronology of operations. For each disputed incoming payment, note the date, amount, P2P order, counterparty, how the cryptocurrency was obtained, and the further movement of hryvnia.
- Match bank transfers to orders. The amount, date, and time of the payment should logically correspond to P2P platform data. If one order was paid with several transfers, explain that separately.
- Prepare proof of asset origin. Exchange history alone shows that an operation occurred, but does not always explain the original source of the cryptocurrency. Where needed, add information about acquisition, income, investments, payment for work, or another lawful source. See also the article on proving Source of Funds.
- Provide the bank with a coherent explanation. The documents should form one consistent picture, not a set of unrelated screenshots.
Do not give the bank or any “intermediaries” a seed phrase, private key, exchange password, or two-factor authentication codes. Those data are not needed to confirm trades.
Which documents help confirm P2P operations
The exact package depends on the circumstances, but it may usually include:
- a bank statement for the relevant period;
- P2P order history with dates, amounts, and statuses;
- the exchange account identifier and proof that the account belongs to the customer;
- TxIDs, wallet addresses, network, and digital asset name;
- history of deposits, purchases, sales, and cryptocurrency withdrawals;
- contracts, invoices, acts, tax returns, income certificates, or other documents explaining the source of funds;
- an explanatory letter with a matching table between P2P orders and hryvnia payments;
- where needed — an analytical report on digital asset movement and risks of related addresses.
Screenshots are better supplemented with statement files and exchange exports. Dates, amounts, identifiers, and other data that allow the link between operations to be verified should be visible. Do not edit images so as to hide material information.
If the bank does not explain how to submit documents, does not consider the request, or breaches the established procedure, the customer may use the internal complaint process, contact the National Bank, or obtain individual legal assistance. At the same time, the bank may be limited by law in disclosing certain information about financial monitoring measures.
Please note: this article is informational. The outcome of a review depends on the actual operations, documents, the customer’s financial profile, and the bank’s risk assessment.
