Deposits at Duel.com are made in cryptocurrency exclusively. The platform holds no fiat balance in any national currency, and what sometimes appears to be a "card deposit" is in fact the purchase of cryptocurrency through an external provider followed by transfer to the balance — a distinction that changes both the fees and the party responsible for the transaction, and one explained in detail below.
Six steps to fund a balance
- Prepare the wallet Cryptocurrency must already be held in an external wallet or on an exchange. A deposit is a transfer between two wallets, not a conventional payment.
- Open the wallet page inside the account select deposit, then choose the required coin from the list.
- Select the network Some coins run on more than one network. USDT, for instance, trades on TRC20, ERC20 and others, each with an entirely different address. This is the decisive step in the whole operation.
- Copy the deposit address using the copy control or by scanning the QR code. Typing the address by hand is not acceptable: a single wrong character sends the funds to a destination nobody owns.
- Execute the transfer from the external wallet pasting the address and confirming that the selected network matches on both sides, then sending the amount.
- Wait for network confirmations The balance credits once the required confirmation count is reached. That takes anywhere from seconds to tens of minutes depending on the coin and network congestion.
The costliest error in crypto casinos: the wrong network. Sending USDT over ERC20 to an address designated for TRC20 produces no error message and returns nothing — the funds go to an address that is technically valid on a different network and become unreachable to both parties. Neither the platform nor the provider has any means of reversing the transfer. The practical rule: match the network name literally between the deposit screen and the sending screen before confirming, and run a small test transfer when using a coin or network for the first time.
Supported coins and available networks
The platform supports 16 coins across 23 deposit and withdrawal rails, per the official wallet source verified in August 2026: BTC, BCH, ETH, LTC, USDT, USDC, SOL, BNB, XRP, DOGE, TRX, ADA, LINK, AVAX, HBAR and GRAM.
| Coin | Network | Typical fee | Confirmation speed |
|---|---|---|---|
| USDT · USDC | TRC20 | Very low | Seconds to minutes |
| USDT · USDC | ERC20 | High and volatile | Minutes |
| LTC | Litecoin | Low | Minutes |
| SOL | Solana | Very low | Seconds |
| TRX | Tron | Very low | Seconds |
| XRP | XRP Ledger | Very low | Seconds |
| DOGE | Dogecoin | Low | Minutes |
| BTC | Bitcoin | Variable with congestion | Tens of minutes |
| ETH | Ethereum | High and volatile | Minutes |
| BNB · ADA · AVAX · LINK · HBAR · BCH · GRAM | Native networks | Low to moderate | Seconds to minutes |
The practical choice: for small amounts, low-fee networks such as TRC20, Solana and Tron preserve a higher share of the sum — a network fee of a few dollars on a ten-dollar deposit consumes a considerable part of it. For larger amounts fees become marginal and the choice is better made on whichever coin the player already holds. Stablecoins such as USDT and USDC add a benefit independent of fees: they neutralise exchange rate movement between the moment of deposit and the moment of withdrawal.
Buying cryptocurrency by card on the site
For those holding no cryptocurrency at all, the site offers an alternative route through a specialist external provider accepting Visa and Mastercard alongside local payment methods in some markets such as Apple Pay, Pix and Blik. Describing this route precisely is necessary to understand what actually happens to the money.
Three direct consequences follow from that ordering:
- The operation is not a fiat deposit. The resulting balance is digital, and later withdrawals are made in cryptocurrency rather than back to the card. The route runs one way.
- Processing fees apply. They are charged by the external provider rather than the platform, and are typically higher than ordinary network fees. The claim of "fee-free deposits" refers to direct crypto transfers only.
- The bank may decline. Many banks refuse cryptocurrency purchases or gambling-related transactions based on merchant category codes. In jurisdictions where the activity is prohibited, the refusal occurs at the payment service provider level and cannot be circumvented by the player.
Limits, fees and crediting time

| Maximum deposit | None | — | Passing €5,000 cumulatively triggers mandatory identity verification |
| Deposit fees | None | The platform | Network fees are always borne by the sender |
| Card purchase fees | Processing fee | External provider | Outside the platform's control |
| Time to credit | Seconds to tens of minutes | The network | Depends on the coin and congestion |
Why depositing in Kuwaiti dinars or via KNET is not possible
The question recurs and the answer has two independent components, each sufficient on its own.
The structural reason: the platform operates no fiat balances whatsoever. There is no account infrastructure in national currencies, no agreements with local banks or national payment networks such as KNET, and no destination a dinar transfer could reach.
The regulatory reason: in countries prohibiting gambling, Kuwait among them, national payment networks and banks do not process this class of transaction. The barrier here sits well upstream of the platform, at the bank and payment service provider level.
Any party advertising a "deposit in Kuwaiti dinars" or "payment via KNET" on this platform is advertising a service that does not exist. Such offers typically appear on domains impersonating the brand or through unofficial intermediaries, and funds sent through them reach no gaming account. Kuwait is in any case on the operator's restricted-country list.
The deposit has not arrived: the handling path
- Check the transfer status on-chain Copy the transaction identifier from the sending wallet and inspect it in the blockchain explorer for that network. If the transaction is pending, the issue is network congestion rather than a fault at the platform.
- Match the address and network Compare the destination address shown in the transaction against the one displayed on the deposit page, and confirm the networks match. A mismatch is the most common cause.
- Contact support with complete information The transaction identifier, network name, coin, amount and time of sending should all be included. A complete message is handled on the first reply; an incomplete one consumes an extra round or two. Live chat is available 24/7 with a median response of around a minute, and email at around two hours.
