Crypto in, crypto out: the full Duel payments manual

Every fiat gambling payment passes through a chain of intermediaries — card schemes, acquiring banks, payment processors — and each link adds delay, fees, and a veto. The notorious «pending withdrawal» of fiat books isn't incompetence; it's the chain working as designed, with fraud holds and batch processing at every hop. Crypto deletes the chain. A deposit is a transaction you broadcast; a withdrawal is a transaction the platform's automated system signs — usually within seconds of the request, because there is no reversible rail behind it requiring human review.

The same finality is why crypto platforms can run the friction-free verification model covered on our no-KYC page, and why the rakeback system can pay withdrawable cash instantly rather than bonus credits. The trade-offs are crypto's own: transactions are irreversible (a mistyped address is a lost payment), networks charge variable fees, and volatile coins move in value while you play. Each coin page below covers its specific profile — Bitcoin, Ethereum, USDT and Solana get full guides; the rest are summarised in the table.

The flow is identical for every coin: open the cashier, pick the coin, and the platform generates your personal deposit address (plus a QR code). Send from your wallet or exchange; the balance credits after the network's standard confirmations — seconds on Solana, a few minutes on most chains, longest on Bitcoin.

The four rules that prevent every common disaster. Match the network to the address. USDT exists on multiple chains; sending TRON-USDT to an Ethereum address is the classic irreversible error — the cashier states which network each address expects. Send a test amount first on your first deposit of any new coin; the few cents of extra fees buy certainty. Mind exchange withdrawal delays — your deposit speed includes your exchange's processing queue, which can dwarf the network's own time. Respect minimums — sub-minimum deposits can be lost or require support intervention; the cashier lists the floor per coin.

One property of crypto bankrolls deserves explicit treatment: unless you use stablecoins, your balance has two sources of variance — your betting results and the coin's price. A winning week in BTC terms can be a losing week in your home currency, and vice versa. The clean mental model is to pick a unit of account and judge everything in it: if your bankroll is USDT, think in dollars; if it's BTC, think in sats and accept the fiat value as weather. Mixing units is how winning bettors convince themselves they're losing and losing bettors convince themselves they're winning.

Keep records regardless — date, coin, amount, and transaction ID for every deposit and withdrawal. It costs seconds (every transaction is already on-chain; you're just indexing them), reconciles your true results across coins, and answers any future tax question your jurisdiction may ask, a topic our no-KYC guide treats honestly. The platform shows your transaction history; your own ledger makes it portable.

Crypto transfers fail rarely, but when they stall the diagnosis follows a fixed ladder. Step one: the block explorer. Paste your transaction ID into the relevant chain's explorer — if the transaction shows as unconfirmed, the network is still working and the fix is patience (or, on Bitcoin, a fee-bump if your wallet supports it). If the explorer shows it confirmed but the balance hasn't credited, step two: count the confirmations against the platform's requirement — crediting follows the threshold, not the first confirmation. If confirmations are ample and the balance is still missing, step three: verify the address and network you actually sent to against what the cashier issued — the moment of truth for cross-network mistakes. Only after those three checks is it a support-ticket matter, and arriving with the txid, the explorer link and the timestamps turns a multi-day back-and-forth into a single exchange. The deeper lesson: every step of that ladder is public information — on-chain transparency means you are never waiting in the dark the way fiat pending-payment queues force you to.
