Key takeaways
- Only 4 of the 9 casinos we review support cryptocurrency — Crocoslots, Bitkingz, Oshi and Spirit Casino. Spin Casino, All Slots, JackpotCity, Lucky Nugget and Kiwi's Treasure are all fiat-only.
- Oshi and Spirit Casino are tied for the widest coin selection at 6 cryptocurrencies each — not a single clear leader, despite what either operator's own marketing might suggest.
- Crocoslots and Bitkingz both support 5 coins (Bitcoin, Ethereum, Litecoin, Dogecoin, XRP) via the same Coinspaid processor, with instant processing.
- Crypto processing is instant at Crocoslots, Bitkingz and Spirit Casino; Oshi doesn't explicitly break out a separate crypto processing time in its own published data.
Cryptocurrency support is genuinely rare across the casinos we review — most of the market still runs on cards and e-wallets only. We went through the exact coin lists published by each of the 4 crypto-friendly operators to see who really offers the widest selection, rather than repeating whichever casino's own marketing claims "the most."
Crypto casinos in NZ
Six cryptocurrencies processed instantly via CoinsPaid, at a flat NZ$30 minimum for both deposits and withdrawals. Tied with Oshi for the widest coin selection of any casino we review — not the outright winner some marketing copy suggests.
Six cryptocurrencies, including Ripple which none of the other three crypto casinos on this list support. Oshi's own published data breaks out e-wallet (0–1 hours) and card/bank transfer (1–5 days) withdrawal speeds separately, but doesn't state a distinct crypto processing time — worth confirming directly with support if timing matters to you.
Five cryptocurrencies processed instantly through the Coinspaid processor, alongside a wide spread of cards and e-wallets. Large first withdrawals typically involve an identity check that adds time outside the crypto rail itself.
Same 5-coin lineup and instant processing as Crocoslots, plus a standout feature: in-account crypto conversion and direct crypto purchases via Mercurio and MoonPay, useful if you don't already hold crypto before signing up.
No crypto support at all
Five of the nine casinos we review — Spin Casino, All Slots, JackpotCity, Lucky Nugget and Kiwi's Treasure — run entirely on fiat banking rails with zero cryptocurrency option, and are upfront about it in their own terms. If Bitcoin or another coin is a requirement for you, these five are off the table regardless of how they otherwise rank on bonuses or game selection. Spin Casino, for instance, is our highest-scoring casino overall, but it's fiat-only end to end.
Pros & cons of crypto casino play
| Pros | Cons |
|---|---|
| Instant processing at 3 of the 4 crypto-friendly casinos (Crocoslots, Bitkingz, Spirit Casino) | Only available at 4 of the 9 casinos we review — over half our list is fiat-only |
| Bitkingz's Mercurio/MoonPay integration lets you buy crypto directly in-account if you don't already hold any | Crypto price volatility between deposit and withdrawal isn't something any casino terms cover — that risk is yours alone |
| Oshi and Spirit Casino both offer 6-coin selections, covering most major cryptocurrencies | Oshi doesn't publish a separate crypto withdrawal time, so exact speed needs confirming with support |
How to deposit with crypto
Choose a crypto-supporting casino
Only Crocoslots, Bitkingz, Oshi and Spirit Casino accept cryptocurrency among the 9 casinos we review.
Set up a wallet or use in-account conversion
Bitkingz uniquely lets you buy crypto directly through Mercurio or MoonPay if you don't already hold any — elsewhere, you'll need your own external wallet.
Deposit the minimum or more
All four crypto casinos use the same NZ$30-equivalent minimum transaction size.
Complete identity verification before your first withdrawal
Even "instant" processors like Coinspaid and CoinsPaid sit behind a one-time KYC check on larger first withdrawals.
Terms you must know
- Spirit Casino and Oshi are tied at 6 coins each, not one clear leader — check the specific coin list for the one you hold before assuming either is "the widest."
- Crocoslots and Bitkingz share the same 5-coin list and processing infrastructure — Coinspaid — so their crypto terms are functionally identical.
- Crypto price movement between deposit and withdrawal isn't covered by any casino's terms. That volatility risk sits entirely with you as the player.

Responsible gambling
Cryptocurrency's price volatility adds a layer of risk on top of the gambling itself — a winning session can look different in NZD by the time you convert it back.
