Quick answer
If you are new to crypto and new to Duel.com at the same time, you are learning two things at once. This guide covers the crypto side in plain language — enough to deposit, play, and withdraw without needing to understand consensus algorithms or smart contract bytecode.
What cryptocurrency actually is
Cryptocurrency is digital money that exists on a blockchain: a public ledger maintained by a decentralised network of computers. No bank sits in the middle. When you send crypto, the network records the transfer permanently.
Key facts
- Key property
- Transfers are irreversible
- You control funds via
- Private keys / seed phrase
- Transfer cost
- Network fee (gas) paid to validators
- Transfer speed
- Seconds to hours, chain-dependent
For gambling purposes, the important implications are:
- No chargebacks. Once crypto leaves your wallet, it does not come back unless the recipient sends it back.
- You are responsible for accuracy. Wrong address or wrong network means lost funds, not a support ticket that fixes it automatically.
- Fees are real and variable. Every transfer costs something, and the amount depends on which blockchain you use.
The three things you interact with
Step 1
Your wallet
Holds your crypto
Step 2
The network
The blockchain you send on
Step 3
The platform
Generates a deposit address
Step 4
Confirmations
Network verifies the transfer
Step 5
Balance credited
You can play
1. Coins (assets)
Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Solana (SOL), and stablecoins like USDT and USDC are common examples. Each has a ticker symbol and a market price that can change (except stablecoins, which aim to stay at $1).
2. Networks (blockchains)
This is the part that trips up most beginners. A coin can exist on multiple networks. USDT, for example, lives on Ethereum, Tron, Solana, and others. The token name is the same; the underlying chain is different, and they are not interchangeable during a transfer.
See choosing the right network for the full explanation.
3. Wallets (where you store crypto)
A wallet is software (or hardware) that holds your private keys and lets you send and receive crypto. You need one before you can deposit. Setup guide: how to set up a wallet.
Stablecoins vs volatile coins
| Type | Examples | Balance while playing | Best for |
|---|---|---|---|
| Stablecoin | USDT, USDC | Stays at ~$1 | Predictable session bankroll |
| Volatile | BTC, ETH, SOL | Rises and falls with market | Users who want crypto exposure |
If a $100 deposit in BTC drops to $90 while you are playing, your effective bankroll shrank by 10% through no fault of your betting. Stablecoins eliminate that. Details: stablecoins explained.
How a deposit works, conceptually
You hold crypto in your wallet
Purchased on an exchange and withdrawn to your wallet, or held directly in a self-custody wallet.
The platform gives you a deposit address
Generated for a specific coin on a specific network. This address is the destination for your transfer.
You send from your wallet to that address
Your wallet deducts the amount plus a network fee. The transaction broadcasts to the blockchain.
The network confirms the transaction
Miners or validators include it in a block. Each subsequent block adds a confirmation. See blockchain confirmations explained.
The platform credits your balance
After enough confirmations, your playable balance updates. This is automatic once the threshold is met.

Fees: what you pay and to whom
Every blockchain transfer incurs a network fee (sometimes called gas). You pay this from your wallet; it goes to the network validators, not to the gambling platform.
| Feature | Typical fee | Speed |
|---|---|---|
| Tron (TRC-20 USDT) | Under $1 | Under a minute |
| Solana (SPL tokens) | Under $0.01 | Seconds |
| Litecoin | Under $0.10 | 2–5 minutes |
| Ethereum mainnet | $1–$20+ | 2–10 minutes |
| Bitcoin | $1–$10+ | 10–60 minutes |
Deep dive: gas fees and network costs.
Common beginner mistakes
- Sending on the wrong network — the most expensive mistake in crypto
- Assuming the deposit is instant — confirmations take time
- Ignoring network fees when depositing small amounts
- Depositing volatile coins without understanding balance can shrink independently of results
- Storing large amounts on the platform instead of in your own wallet
- Not testing with a small amount on a new coin or network combination
Security essentials
You do not need to become a security expert, but three rules are non-negotiable:
- Never share your seed phrase with anyone or any website
- Enable 2FA on your gambling account before depositing
- Verify the domain before logging in — bookmark the genuine site
- Verify deposit and withdrawal addresses after pasting
- Keep only session funds on the platform; store the rest in your wallet

Summary
Crypto gambling uses the same games with a different money layer. You hold coins in a wallet, send them on the correct network to a platform-generated address, wait for confirmations, and play. Choose stablecoins on cheap networks for predictable costs. Treat every transfer as irreversible. Enable 2FA, verify addresses, and test small before committing large amounts.
