There is the minimum to fund an account (a small per-coin amount) and the minimum to arm the welcome package, which is a qualifying deposit of at least 30 USDT or the crypto equivalent. Confusing the two is the easiest way to deposit and then wonder why the bonus did not attach.
Seven coins, no casino-side fees
mBit Casino has been crypto-only since 2014: Bitcoin, Ethereum, Litecoin, Dogecoin, Bitcoin Cash, Tether (USDT) and Ripple (XRP). There is no Interac, card or bank route. mBit Casino charges nothing to deposit or withdraw on any of the seven; the only cost is the network fee your own wallet sets.
Per-coin minimum deposits
The account-funding minimums below are reported by AskGamblers and are the only published figures for them, so treat the table as single-source and confirm in the cashier on the official site. Several sit well under 30 USDT in value, so a bare minimum deposit can leave the welcome tier untriggered.
| Coin | Reported minimum deposit |
|---|---|
| Bitcoin (BTC) | 0.35 mBTC |
| Ethereum (ETH) | 0.01 ETH |
| Litecoin (LTC) | 0.14 LTC |
| Dogecoin (DOGE) | 115 DOGE |
| Bitcoin Cash (BCH) | 0.05 BCH |
| Tether (USDT) | 10 USDT |
| Ripple (XRP) | 25 XRP |
Which coin to send
Because the bonus floor is quoted in USDT, a stablecoin deposit is the one where you know exactly where you stand: 30 USDT clears the threshold with no price guesswork. With a volatile coin the value of the same amount moves with the market, so it might qualify one day and fall short the next. Litecoin and Dogecoin usually confirm faster and cost less to move than Bitcoin on-chain, while Ethereum gas can cost more than either.
Withdrawals
Payouts go back on-chain to the wallet you name, fee-free on the casino side. Many Trustpilot reviewers (4.4/5 across 483 reviews) report crypto withdrawals within hours, while Reddit, Bitcointalk and the AskGamblers forum carry recurring reports of delayed or withheld cashouts and slow KYC. Completing verification early is the sensible precaution. The withdrawal guide covers speed and the reported limits.
