21bit review for Australian players
21bit is the fastest payer on the list: it advertises instant withdrawals, and it accepts Bitcoin and Ethereum alongside standard methods.
Our verdict
21bit scores 9.8 out of 10. Fastest cash-out here, with Bitcoin and Ethereum. It suits careful starters who want a $15 entry, anyone who values instant crypto payouts and people who pay by Apple Pay.
Welcome offer
21bit advertises a 225% match up to $3,400 with 100 free spins. Try the calculator to see what your deposit could turn into.
Illustration only: multiplies your deposit by the headline match, capped at the advertised maximum. Real welcome packages are often split across several deposits and may carry conditions.

Is 21bit legal in Australia?
21bit is licensed in Curaçao, not in Australia. Under the Interactive Gambling Act 2001 operators may not offer online casino games to people in Australia, and the regulator can block sites. Players are not the target of the law, but you get no Australian consumer protection. Read the full explainer.
