You deposit with crypto, you win, you request a withdrawal, and then 1Win asks for proof of where the money came from. That request is normal. What is not normal is the reply many players send back: a phone screenshot of their wallet balance, or a cropped image of a single incoming transfer. The withdrawal stays frozen, the support ticket goes quiet, and a routine check turns into a week of back and forth. A 1Win review will tell you the platform is licensed in Curaçao, which means source of funds checks are a legal obligation, not a mood swing from the payments team.

The mistake is not the request itself. It is answering it with the wrong format. A screenshot shows a number at a moment in time. It does not show where the coins came from, how long they sat in the wallet, or whether the address on screen is the same one you deposited from. Investigators work with transaction trails, not pictures of them. When the document does not connect a blockchain address to a verified exchange account, the file is bounced and the clock on your payout restarts.

This piece walks through what actually satisfies a 1Win AML source of funds request, why wallet screenshots fail, and how to export the right files the first time. If you use 1Win sports betting or the 1Win casino and fund your account with crypto, this is the one procedure worth learning before you need it.

Understanding AML Source of Funds Requests at 1Win

1Win was founded in 2016 and operates under a Curaçao license held by MFI investments Ltd. That license is the reason a withdrawal can stop mid-flow and a request for source of funds lands in your inbox. Curaçao rules require licensed operators to run anti-money laundering checks, and a bookmaker that skips them risks its license. So the request is not a personal attack on your account. It is a compliance step that every licensed betting platform has to perform.

What most players miss is that source of funds is not the same as identity verification. A passport confirms who you are. A bank statement or exchange export confirms where the money came from. 1Win asks for the second when the first is already done and the numbers still look odd.

Several things trigger a review. A deposit pattern that jumps from 20 $ to 3,000 $ in a week. A withdrawal requested within minutes of a deposit, with almost no betting activity in between. Multiple accounts sharing a device, IP, or wallet address. A cryptocurrency deposit from a wallet that has no visible history. Any single flag can push a cashout into manual review, and crypto transactions get extra attention because blockchain records are pseudonymous.

Here is the practical part. Source of funds checks usually happen at withdrawal, not at deposit. Money going in is easy to accept. Money going out is where the operator carries legal risk, so that is where the paperwork appears. If you have 1Win bonuses active, read the terms before you panic: bonus wagering and AML review are separate processes, but a frozen withdrawal pauses both.

In a broader 1Win review, this is the unglamorous side of the product. The 1Win casino side with its 14,000+ slots and 500+ live dealer games, the 1Win sports betting markets, the welcome bonus of +500% on deposit, the cashback up to 30%, the 0.5 $ minimum deposit, the iOS and Android apps: none of it matters if you cannot withdraw. Treat AML as part of the cost of using a licensed operator, prepare documents before you need them, and the process takes days instead of weeks.

The Crypto Wallet Screenshot Mistake That Delays Withdrawals

A wallet screenshot shows a balance and maybe a few recent transfers. That is all it proves. It does not show where the coins came from, how they were acquired, or whether the same wallet sent money to 1Win in the first place. AML analysts at the bookmaker need a traceable chain from source to deposit, and a phone screenshot breaks that chain at the first step.

Worse, screenshots are trivially editable. Anyone with an image editor can change a number, a date, or a wallet address in under a minute. Compliance teams know this, which is why a PNG of a Trust Wallet or MetaMask screen is treated as unverified information. It does not matter that your screenshot is genuine. The format itself carries no evidentiary weight, so the reviewer cannot tick the box and the request stays open.

What Actually Happens After You Upload a Screenshot

The request does not get rejected outright. It goes back into the queue with a note asking for the same documents again, and the clock restarts. In practice this means:

• Your withdrawal stays pending while the review is open, sometimes for days per round of back-and-forth.
• Each resubmission adds another review cycle, and the queue is not first-come-first-served.
• Repeat incomplete submissions can flag the account for closer scrutiny, which slows future cashouts too.
• In the worst case, the risk team applies a temporary block on withdrawals until the source of funds is fully documented.

None of this is unique to 1Win. Any licensed operator working under a Curaçao license has to keep records that satisfy its regulator, and a screenshot does not satisfy anyone. The mistake is not that you deposited crypto. Crypto payments are fully supported, and there is no penalty for using them. The mistake is answering a documentary request with evidence that cannot be audited.

There is a second, quieter problem. If the wallet address in your screenshot does not match the address that funded your 1Win deposit, the reviewer now has two conflicting data points to resolve. That turns a routine check into an investigation, and it is entirely avoidable.

The fix is simpler than most people expect: send the raw export, not a picture. The next section covers exactly which files 1Win wants and how to pull them.

What 1Win Actually Requires: Full CSV Transaction Histories

A screenshot of your wallet balance tells the AML team nothing they can verify. It is a picture, not a record. What 1Win’s compliance department asks for is the transaction history behind the money: a CSV export from the exchange or wallet you used before the funds reached the betting platform. This is the same standard banks apply when you move a large sum, and it exists because 1Win operates under a Curaçao license and has to show where player money comes from.

In practice, a compliant file from Binance, Bybit, Kraken, or Coinbase contains a row per movement with a timestamp, asset, amount, network, and both the sending and receiving wallet addresses. That last column is where most players trip up. 1Win needs the wallet address in your history to match the address you originally deposited from. If you deposited from wallet A but your CSV shows activity from wallets B, C, and D, the reviewer cannot connect the dots and the request comes back for more detail.

What the team typi. 1win aviatrix offers additional context worth reviewing. cally wants to see:

• Full CSV export covering the period in which the deposit was made, not a trimmed extract
• Wallet addresses that match the deposit source on file
• Exchange account details showing the account holder’s name
• Fiat on-ramp records if you bought crypto with a card or bank transfer
• A brief written explanation if funds passed through an intermediary wallet

There is a practical trap here. Many players keep funds spread across multiple wallets and top up a deposit from whichever one has a balance that day. From the AML side, that looks like money arriving from an unrelated third party, which triggers further review. If you use a self-custody wallet as an intermediate step, expect to provide the on-chain history for that wallet too.

PDF bank statements are usually accepted for fiat deposits, and exchange-issued statements work in place of a raw CSV when the CSV is unreadable. What does not work is a phone photo of a wallet screen, a cropped balance view, or a chat message from a friend confirming a transfer. The rule is simple: the document must let a reviewer trace the money from its origin to the 1Win deposit address without gaps.

Step-by-Step: How to Prepare and Submit Compliant Source of Funds Documents

When 1Win asks for source of funds, the request is usually specific: a full transaction history from the exchange or wallet service you used to fund your account. Random screenshots won’t pass. Here is the exact process that works.

Step 1: Identify the original deposit route. Open your 1Win account history and find the deposit that triggered the review. Note the amount, date, coin or currency, and the wallet address you sent from. That address is the anchor for everything else. If you deposited via a personal wallet, you will need the exchange history showing how coins arrived at that wallet in the first place.

Step 2: Export a full CSV from your exchange. Log into the platform you used (Binance, Kraken, Coinbase, Bybit, or similar), go to the transaction or wallet history section, and export a CSV covering a window that includes the deposit date plus at least three months before it. Do not trim the file. Partial histories raise more questions than they answer. If you used multiple exchanges, export from each one.

Step 3: Align wallet addresses. Open the CSV and confirm that the withdrawal address listed matches the wallet address you used to fund 1Win. This is where most players fail. A CSV showing a Binance withdrawal to an address you no longer control, or to a different wallet than the one that hit 1Win, breaks the audit trail. If you routed through an intermediate wallet, export that wallet’s history too. The chain must be continuous: exchange, wallet, 1Win.

Step 4: Prepare the document set. You typically need the CSV files, a short written explanation of the deposit route, and a screenshot of the wallet address itself (not the balance, the address). Label each file clearly: exchange name, date range, and purpose. Convert everything to PDF or keep CSVs intact, since many verification teams cannot open proprietary formats.

Step 5: Submit through the correct channel. Use the verification section in your 1Win account dashboard or reply to the compliance email with attachments. Do not send documents to support chat. Do not upload to third-party file hosts. If the file exceeds the upload limit, split it by month and note the sequence.

Step 6: Follow up once, politely. Compliance reviews at 1Win typically take 24 to 72 hours. Send one follow-up after three business days if you have heard nothing. Repeated messages slow the queue for everyone, including you.

Consequences of Non-Compliance and How to Protect Your 1Win Account

Refusing to hand over a full CSV history is not a neutral act. Under anti-money laundering rules, an operator that cannot match the money leaving the account to a verified origin has to treat the funds as unexplained. At 1Win that typically means the wager stays in the balance while the withdrawal is frozen, not rejected outright. You will still see the money in your account, which makes the situation feel temporary. It is not. Until the file lands in the verification queue, the payout does not move.

Escalation follows a predictable path. A first missed deadline triggers a reminder and a fresh 72-hour window. Ignore the second and the compliance team can restrict withdrawals entirely, void pending 1Win bonuses, and in the worst case close the account under the terms of the Curaçao license, returning the remaining balance minus processing costs. Accounts closed for AML reasons also land on internal watchlists, so opening a new profile with the same ID or email rarely works.

Prevention is mostly admin hygiene, and it takes less time than the dispute it avoids.

• Keep exchange exports current. Download a CSV from Binance, Kraken, or your wallet provider every month and store it with the deposit date in the filename.
• Deposit from one source. Mixing cards, e-wallets, and crypto across a single account makes the audit trail impossible to reconstruct later.
• Do not move funds between wallets before depositing. A hop through a second address breaks the link to the exchange record.
• Verify early. Completing account verification before your first cashout removes the trigger that starts a review.
• Watch the clock. Answer requests inside the stated window, even if only to say the export is coming.

Players who use 1Win sports betting and 1Win casino products heavily should treat documentation as part of the bankroll. A 500+ live casino game catalogue and 14,000 slots generate large turnover, and large turnover draws attention. Keeping clean records means a cashback payout up to 30%, free spins, and any active 1Win bonuses survive the process instead of being cancelled at the point of withdrawal.

The pattern worth remembering: the platform asks once, the player answers with a screenshot, the file gets bounced, and three weeks disappear. A CSV and a matching wallet address take an afternoon to assemble. That is the whole trade-off.

The single most useful habit you can build before your next cashout is a dedicated folder on your device or in cloud storage. Every time you deposit crypto to 1Win, drop the exchange CSV for that transaction into it, name the file with the date and the amount, and paste the sending wallet address into a plain text note. Five minutes of housekeeping per deposit saves days of back-and-forth later. If you use multiple exchanges or self-custody wallets, keep one subfolder per source so the wallet address on your 1Win deposit matches the withdrawal address on the exchange statement without guesswork.

Then run a dry test. Request a modest withdrawal, well under any threshold that would trigger a full source of funds review, and watch how the process behaves for your account. If a request for documentation does arrive, export the full CSV from the exchange, not a screenshot, not a PDF summary page, and submit it through the verification section of your account dashboard. Keep the ticket reference. If you have already sent screenshots and the review is stalled, send the CSV proactively with the same ticket number rather than opening a new one. Accounts that respond with complete files in one pass clear review faster than accounts that trickle documents in over several days. Documenting your funds properly also protects the 1Win bonuses and cashback you have accumulated, since promotional balances typically sit behind the same verification gate as your principal.
