How crypto payments actually work

Named assets are not the same as network support

Operators list supported coins in cashiers and guides. Our index snapshot counts operators publishing between roughly a dozen and twenty-one named assets. But an asset name hides the important detail: which network. USDT exists on Ethereum, TRON, Solana and others; sending it on the wrong chain to a deposit address expecting a different one is the classic irreversible mistake. Good cashier pages state asset-and-network pairs explicitly. Where an operator lists "ERC-20 tokens" or "SPL tokens" as families without enumerating every asset, treat any specific token as unsupported until confirmed.

Confirmations: why deposits wait

A deposit is not spendable when it appears; most operators credit after a number of network confirmations. Those vary by asset. Bitcoin typically needs more than Litecoin, while some stablecoin chains need fewer. They confirmation time depends on congestion and the fee you attached. A "missing" deposit is usually one waiting for confirmations; check the transaction on a block explorer before contacting support.

Fee models

• No deposit fees are common, but conversion fees can apply if you fund through fiat rails.
• Withdrawal fees may be flat per route, percentage-based, or passed through as miner fees.
• Internal conversions (say BTC to USDT inside the account) carry spread or explicit fees.
• Minimum withdrawal amounts exist per route; below them requests can fail or be consumed by fees.

Stablecoins and volatility

Many players hold bankroll in volatile assets but wager in stablecoins. Check whether the operator credits stablecoin values 1:1 or applies conversion spreads, and whether bonuses count stablecoin play differently. Volatile-asset balances also mean your effective bet size drifts with the market. Some players convert to stablecoins on deposit purely for accounting sanity.

A safe-transfer routine

1. Match asset symbol and network exactly against the cashier's instructions.
2. Send a minimal test amount first; confirm it credits.
3. Whitelist withdrawal addresses if the operator supports address books with cooldowns.
4. Keep records: tx hashes for every deposit and withdrawal.
5. Never share seed phrases; no casino support agent needs them.

Our comparison marks each operator's published crypto support as source-limited where token families go unenumerated, because "21 supported cryptocurrencies" and "every asset on every network" are very different claims.
