Identity

Identity checks confirm who a bettor is. Source-of-funds checks ask a harder question, namely where the money in the account came from.
Crypto sportsbooks send these requests far less often than ID checks, yet they tend to appear at sensitive moments, such as a large withdrawal or a sudden jump in deposits. Vague answers can hold a payout for weeks.
Bettors who understand the usual triggers and the documents compliance teams accept can turn a stressful email into a routine one.
<h2 id="source-of-funds-versus-source-of-wealth">Source of Funds Versus Source of Wealth</h2>
Compliance teams use two related terms, and requests sometimes mention both. The table sets out the difference.
Term
Question it answers
Typical evidence
Source of funds
Where did these specific deposits come from?
Exchange statements, wallet history, payslips
Source of wealth
How did the bettor build their overall assets?
Employment history, business ownership, investments, inheritance
Identity verification
Who holds the account?
Photo ID, selfie
Address verification
Where does the account holder live?

Source-of-funds checks usually come after identity and address verification. Reviews of this kind follow similar triggers at casinos and sportsbooks, as an explainer on<a href="https://cryptodaily.co.uk/2026/07/withdrawal-reviews-at-crypto-casinos-what-triggers-a-check" rel="noopener noreferrer nofollow"> withdrawal reviews</a> shows.
<h2 id="common-triggers-for-a-request">Common Triggers for a Request</h2>
Anti-money laundering rules ask operators to understand the money moving through each account, especially when activity looks unusual. Several patterns tend to prompt a request.
<h3 id="large-or-cumulative-amounts">Large or Cumulative Amounts</h3>
Big single deposits, large withdrawals or cumulative totals above an internal level often lead to a review. Operators rarely publish the exact figures.
<h3 id="changes-in-behaviour">Changes in Behaviour</h3>
Sudden jumps in deposit size, rapid in-and-out movements with little betting, or play that seems out of line with the account profile can raise questions.
<h3 id="wallet-risk-flags">Wallet Risk Flags</h3>
Blockchain analytics tools score incoming wallets. Funds linked to mixers, sanctioned addresses or high-risk services can trigger a request even on a modest deposit.
<h2 id="documents-that-usually-satisfy-a-request">Documents That Usually Satisfy a Request</h2>
Clear, consistent evidence closes most reviews quickly. Compliance teams commonly accept the following:
<ul>
 <li>Exchange statements: purchase records showing the crypto came from a verified exchange account</li>
 <li>Withdrawal records: exchange outflows matching the deposit hash and amount</li>
 <li>Payslips or tax returns: proof of regular income behind the purchases</li>
 <li>Sale documents: records of selling property, shares or other assets</li>
 <li>Crypto income records: mining, staking or trading history with dates and amounts</li>
</ul>
Connections between documents matter as much as the documents themselves. Payslips, exchange purchases and matching deposit hashes together tell one clear story.
High-volume bettors meet these checks most often, as a comparison of sportsbooks for<a href="https://cryptodaily.co.uk/2026/07/4-crypto-sportsbooks-for-high-volume-bettors-limits-and-withdrawals-compared" rel="noopener noreferrer nofollow"> high-volume bettors</a> on limits and withdrawals explains.

Players who expect larger activity can keep a simple record. Saved exchange statements, noted deposit hashes and straightforward funding routes all make a later answer easier.
Stablecoin funding through a verified exchange often produces the cleanest paper trail. CryptoDaily's guide to<a href="https://cryptodaily.co.uk/2026/07/how-to-fund-a-crypto-sportsbook-with-stablecoins" rel="noopener noreferrer nofollow"> stablecoin funding</a> covers the steps.
Honest, complete answers matter most. Altered or missing documents usually extend a review or end in account closure.

Fraud investigations can pause account operations for up to 14 business days.
Dexsport also applies a turnover rule, so every deposit needs wagering once on sports at minimum odds of 1.3, or twice through casino play, ahead of a withdrawal. That turnover rule discourages deposits made only to move funds through the platform.

<h2 id="conclusion">Conclusion</h2>
Source-of-funds requests ask where the money in a sportsbook account came from, and they usually follow identity and address checks. Large or cumulative amounts, sudden behaviour changes and wallet risk flags commonly trigger them.
Exchange statements, matching withdrawal records, payslips, sale documents and crypto income records satisfy most requests, especially when they link into one clear trail. Altered or incomplete evidence tends to prolong a review.
Dexsport combines open-ended ID requests with a turnover requirement on deposits. Keep records of every funding route. Betting laws differ from one country to another, so confirm where you stand, bet only at legal age and expect that KYC or AML checks may apply.
