Optimism casinos are few and far between. So few, in fact, that we’ve only recommended two casinos that accept OP in this guide.
Even so, there’s much to know about Optimism and its native currency, OP, and how it’s an excellent (albeit niche) cryptocurrency for gambling online.
Let’s dive straight in:
Which Casinos Accept OP?
Right now, there are only two OP-friendly casinos we can wholeheartedly recommend. Let’s start with our top pick:
BC.Game: Best OP-Friendly Casino

❌ KYC may be required
Overview
BC.Game is a well-rounded crypto casino that sits at position two on our list of the best crypto casinos in general. It’s an added bonus that BC.Game is one of the few casinos out there that accepts OP.
The platform has an excellent welcome bonus up to the value of $220,000 (or OP equivalent) split over your first four deposits.
You can claim the first match of 180% if you deposit a minimum of 4.044775666629589 OP. You can claim three more match deposit bonuses if you successfully unlock your winnings.

BetFury: Anonymous OP Gambling
Fast Facts
Established: 2019
License: Curaçao
Best for: Anonymity (no KYC)
Pros & Cons
- Three welcome bonus options to choose from
- No KYC requests
- 8,000+ games available
- Regular tournaments and special promos
- Frequent Lucky Wheel spins up for grabs
❌ Less favorable OP limits compared to BC.Game
Overview
BetFury is a casino for the people–offering three different welcome bonus packages. The biggest is a 150% deposit match up to $2,500 (or OP equivalent) plus 50 free spins when you deposit a minimum of 203.417412 OP.
Like BC.Game, BetFury has a phenomenal game selection (over 8,000 titles) that you can bet on using OP. The platform also has an excellent sportsbook and regular sport-specific promotions.
But BetFury’s crowning glory is likely the fact that it’s anonymous. In other words, you won’t be asked to complete a KYC check before you withdraw your funds (unless you’re visibly up to no good).
Now, what about limits?
BetFury OP Limits
| Min. Deposit | Min. Withdrawal | Withdrawal Fee |
| 0.5 OP | 0.5 OP | 0.6 OP |
As you can see, BetFury has a higher minimum deposit amount and a slightly higher withdrawal fee than BC.Game. But if you’re undeterred, you can snag your preferred BetFury welcome package (free spins and all) here:
What Is Optimism?
The Optimism blockchain is a layer-2 scaling solution for Ethereum that aims to increase the speed and reduce the costs of transactions on the Ethereum network.
Layer-2 solutions are secondary frameworks or protocols built atop an existing blockchain system, designed to enhance scalability and efficiency.
Optimism specifically employs a technology called Optimistic Rollups to achieve these improvements.
Optimistic Rollups?
Optimistic Rollups work by executing transactions outside the Ethereum mainnet (layer-1), but posting transaction data back to it.
This approach allows for many transactions to be processed simultaneously in a separate environment, reducing the strain on the main Ethereum chain.
The “Optimistic” part of the name comes from the method’s assumption that transactions are valid by default, and computations are only run to check their legitimacy if someone claims they’re fraudulent.
OP Token
The OP token is the native cryptocurrency of the Optimism network. It serves several key functions within the ecosystem:
- Governance: OP token holders can participate in the governance of the Optimism network, proposing or voting on changes to the protocol.
- Incentives: The OP token is used to reward actions that contribute to the network’s health and security. This includes rewards for validators, developers, and other network participants.
- Fees: While transaction fees on Optimism are generally lower than on Ethereum mainnet, users still need to pay these fees, which can be paid with the OP token.
Have a look at how OP compared to USD in May, 2024:
| OP | USD |
| 1 OP | $2.48 |
| 5 OP | $12.41 |
| 10 OP | $24.83 |
Pros & Cons of Gambling with OP
As is the case with every crypto out there, OP has its share of pros and cons. Namely:
- Lower Transaction Fees: Optimism can significantly reduce transaction fees compared to the main Ethereum network. This bodes well if you’re going to be making various deposits and withdrawals at your chosen OP-friendly casino.
- Faster Transactions: Optimism provides faster transactions than Ethereum’s mainnet by handling transactions off-chain and batching them before finalization on the mainnet. This means less waiting on your behalf.
- Security and Reliability: Although Optimism operates as a second-layer solution, it still benefits from the underlying security of the Ethereum mainnet.
❌ Volatility: OP’s volatility is particularly high—even for crypto standards. The value of your OP may change from one moment to another.
❌ Dependency on Ethereum: Because Optimism relies on the underlying infrastructure of Ethereum, any issues or congestion on the Ethereum mainnet can indirectly affect the performance of Optimism.
❌ Limited Adoption: Optimism casinos are few and far between. BC.Game and BetFury are possibly the only reliable options at this point.
Why Are There So Few Optimism Casinos?
In the eyes of many crypto casinos, OP is just another ERC-20 token (of which there are hundreds) and may not be worth the hassle of adding to their portfolios.
Even so, OP has grown over the past few years, despite its significant volatility:
For this reason, it’s quite likely that more casinos will add this coin to their portfolios in the near future. We’ll be sure to update you when that happens.
Optimism Vs Bitcoin: Which Is Better for Online Gambling?
Whether BTC or OP is better for online gambling depends entirely on you as a player. We can’t decide for you, but here are a few things you should know before you make up your mind:
| Feature | Bitcoin (BTC) | Optimism (OP) |
|---|---|---|
| Blockchain | Own blockchain, using a proof-of-work system. | Layer 2 solution on Ethereum, using rollup technology. |
| Transaction Speed | Varies, often slow during congestion (minutes to hours). | Generally faster due to batch processing of transactions. |
| Transaction Costs | Can be high during peak times. | Lower, more cost-effective for frequent and small transactions. |
| Adoption | Widely accepted in online gambling. | Growing adoption, more niche compared to Bitcoin. |
| Security | Highly secure, well-established with a strong track record. | Benefits from Ethereum’s security but newer and less tested. |
| Stability | Highly volatile but broadly stable in market presence. | Highly volatile, influenced by Ethereum’s ecosystem. |
| Accessibility | Easy to find casinos that accept Bitcoin. | Fewer casinos accept it; hard to find more than a few options. |
Final Thoughts
So there you have it; your guide to gambling with OP. At this point, our list of casinos accepting OP is very short, but we’ll be sure to keep you in the loop if more operators decide to add Optimisim to their portfolios.
For now, BC.Game and BetFury are your best options—both offering solid welcome packages and decent OP limits.
