Crypto Payments at Slamz
By Elin Norrgård, casino analyst — updated August 2026
Slamz operates as a crypto casino alongside its card and bank rails: a crypto deposit is credited once the network confirms it, and a crypto withdrawal is sent back to the same wallet within 24 hours of approval. The practical floor in either direction is around €50 of coin value. The coins accepted are bitcoin, usdt, litecoin and ethereum, and the choice between them matters far more than most guides admit — the network you pick decides both the fee and the wait.
Which coins and which networks
| Coin | Network | Confirmations | Typical wait | Network cost |
|---|---|---|---|---|
| Bitcoin (BTC) | Bitcoin mainnet | 1–3 | 10–40 minutes | Highest, varies with congestion |
| Tether (USDT) | TRC-20 | 1 | 1–3 minutes | Cents |
| Tether (USDT) | ERC-20 | 12 | 3–10 minutes | Ethereum gas, can spike |
| Litecoin (LTC) | Litecoin mainnet | 2–4 | 5–15 minutes | Very low |
| Ethereum (ETH) | ERC-20 | 12 | 3–10 minutes | Gas-dependent |
The single most expensive mistake in this table is sending USDT on the wrong network. TRC-20 and ERC-20 addresses look interchangeable and are not; funds sent to a TRC-20 address over ERC-20 are usually unrecoverable, and no support desk can reverse them. Match the network label in the cashier to the network label in your wallet, every time, even when you have done it before.
Making a crypto deposit
Open the cashier, choose the coin, and the system generates a deposit address with a QR code — treat it as single-use even when it is reusable. Copy it in full or scan it, send from your own wallet, and wait for the confirmations listed above. A bitcoin deposit is credited at the exchange rate captured when the transaction confirms, not when you press send, so a volatile ten minutes can move the credited euro figure by a percent or two either way.
Two habits save trouble. First, send a small test amount the first time you use a new wallet pairing; the €50 floor makes that cheap insurance. Second, keep the transaction hash. If anything stalls, that hash is what support and a block explorer both need — a screenshot of your wallet balance proves nothing.
Making a crypto withdrawal
Payouts go back to a wallet you control, and the operator applies the same-source logic it applies to cards: the address you deposited from is the default target. Requests clear inside 24 hours once approved, usually much sooner, and the blockchain fee is deducted from the amount rather than added on top. Slamz charges no commission of its own on a crypto withdrawal.
Crypto does not exempt anyone from verification. The licence conditions require identity checks on payouts regardless of the rail, so the anonymity a coin gives you is anonymity from your bank, not from the operator. Anyone expecting a nameless cashout will be disappointed; anyone who simply prefers gambling not to appear on a bank statement gets exactly what they came for.
Volatility between deposit and cashout
Your Slamz balance is held in euros, not in coin. Deposit €500 of bitcoin, play for a week, cash out €500 of bitcoin, and the number of coins you get back will differ from the number you sent — sometimes noticeably. That is the exchange rate doing its work, not a fee. Stablecoins remove the effect entirely, which is why usdt is the sensible default for anyone who wants crypto speed without the currency bet on top of the gambling one.
Fees, limits and when crypto is the wrong choice
Crypto has the loosest ceilings of any rail here and the fastest payouts after Trustly, but it is a poor fit in three situations: when you want a bonus that excludes crypto deposits, when you are moving small amounts where a Bitcoin network fee is a real percentage, and when you have never used a wallet before and are also trying to learn a casino cashier at the same time. In those cases Trustly or Skrill does the same job with fewer ways to go wrong.
