JustBit Casino Review

JustBit is an online casino and sportsbook that launched in 2021 and takes both cryptocurrency and regular money. This JustBit review is a factual profile of the brand: what it offers, what we could and could not confirm about who runs it and which licence it holds, and what using an unlicensed offshore operator means for a player.

99Bitcoins does not recommend JustBit. We could not verify a current licence for it, and it is not licensed in the UK, the US or the other regulated markets we checked. You must be 18 or older to gamble, or older where your local law says so.

JustBit Review Summary

JustBit combines a casino lobby with a sports betting section. Earlier versions of this review said it was run by Casbit Group N.V. under a Curaçao licence. When we checked on 5 October 2026, Casbit Group N.V. did not appear on the Curaçao Gaming Authority’s licence register, and the JustBit website, which now redirects from justbit.io to justbit4.io, showed a security check that stopped us from reading its current terms.

In short, we cannot tell you today which company runs JustBit or which licence it relies on. That alone is a reason for caution. It is also not on the UK Gambling Commission register. For readers in a country where it holds no licence, there is no local regulator, no local complaints route and no link to national self-exclusion schemes.

1. Overview

JustBit went live in 2021. When we first reviewed it in 2023, the site offered slots, table games and live dealer games from outside game studios, alongside a sportsbook covering football, US sports, tennis and esports.

We have removed the claims from that earlier review that we can no longer check, such as the number of games, the bet limits and our own impressions from playing. A casino’s game count and features change often, and a first-hand impression from years ago tells a reader nothing reliable about the site today.

What has changed in a way we can check is the web address. The original justbit.io domain now forwards visitors to justbit4.io. Numbered mirror domains are common among offshore casinos. They are often used to stay reachable when a domain is blocked, which is one more sign that a site is operating outside the licensing systems of the countries it serves.

2. Who Runs JustBit

Our 2023 review named Casbit Group N.V., a company registered in Curaçao, as the owner and operator of JustBit, and said it held a Curaçao licence.

Curaçao has since moved to a new system in which the Curaçao Gaming Authority issues licences directly and publishes a licence register. We searched the online gaming list dated 2 October 2026 and the authority’s enforcement register. Neither lists Casbit Group N.V. or a JustBit brand.

We also tried to read the current terms and website footer, which is where an operator normally states its company and licence number. The site showed an automated security check instead, so we could not see them. We do not get round such checks. Until the operator’s details can be matched to a register entry, we treat the licence status of JustBit as unverified.

We searched the UK Gambling Commission public register for both JustBit and Casbit and found no entry. We found no licence from a US state regulator or an EU national regulator either.

Even a valid Curaçao licence would only cover operating from Curaçao. It would not make JustBit legal in countries that require operators to hold their own local licence, which includes most of Europe, the UK and the US states that allow online gambling.

3. Deposits, Withdrawals and Verification

Older versions of this page listed fees, minimum deposits and daily transaction caps. We have removed them because we could not confirm them on the operator’s own pages.

Our earlier review also described fiat withdrawals as needing identity checks while crypto payments did not. We no longer present that as a benefit. Identity and age checks, often called Know Your Customer or KYC, exist to keep minors out, stop fraud and meet anti-money-laundering rules. Licensed operators in regulated markets must carry them out, and a casino that lets some players skip them is not offering extra privacy. It is offering less protection.

In practice, offshore casinos often ask for documents at the moment a player tries to withdraw. If the checks fail, or if the player is found to be in a restricted country, the balance can be held or voided under the operator’s own terms, with no regulator to review the decision.

JustBit Bonuses

Like most crypto casinos, JustBit has advertised welcome offers and other promotions. We do not promote them and do not list amounts, because we cannot verify the current terms and because the operator is not licensed in our readers’ markets.

It helps to know how casino bonuses work in general. A bonus usually comes with a wagering requirement: the bonus, and sometimes the deposit, must be staked a set number of times before any winnings can be withdrawn. Maximum bet rules, excluded games and short expiry dates are common too. Breaking any of them can cancel the bonus and the winnings that came from it.

In regulated markets, regulators set standards for how bonus terms must be written and shown to players. At an offshore casino, the operator writes and enforces them alone.

4. JustBit Casino Games

JustBit’s casino lobby, as we recorded it in 2023, was built around slots from well-known studios, with table games such as roulette and blackjack and a live dealer section.

Slots run on a random number generator and a fixed return-to-player setting. Over time the house keeps a share of every stake, which is why longer sessions tend to cost more. Jackpot slots add a very small chance of a large prize, usually at higher stakes.

Table games such as blackjack involve some decisions, but the house edge still applies to every hand. Live dealer games stream a real table, and they usually require a verified account with your full name and date of birth.

The earlier version of this page said that JustBit did not state its games were provably fair. Provably fair systems let a player check, after the fact, that a single result was not altered. They do not guarantee payouts or fair terms, and they are not a substitute for a licence.

5. JustBit Sports Betting

In 2023 JustBit’s sportsbook offered betting on major football leagues, US sports, tennis and esports, and also on political events and TV awards. We have removed the odds comparison from our earlier review, because odds change constantly and we cannot repeat the test.

Sports betting is licensed separately in many countries, and the rules on what may be offered differ. Some regulators do not allow bets on events such as awards shows or elections at all. An offshore sportsbook applies its own rules instead, including its own rules on voided bets and maximum winnings.

If you bet on sport, look for a bookmaker licensed in your own country. In the US, for example, sports betting is legal only in states that have authorised it, through the state’s own regulator or lottery. In Great Britain, every legal bookmaker appears on the Gambling Commission’s register.

6. JustBit Currency and Payment Methods

JustBit accepted a range of cryptocurrencies, including Bitcoin and Ethereum, and several fiat currencies through cards and e-wallets when we reviewed it in 2023. It also offered a way to buy crypto with a card through a third-party exchange partner.

We do not encourage buying cryptocurrency in order to gamble at an offshore casino. A crypto transfer cannot be reversed by your bank, and if the casino refuses a withdrawal there is no regulator to escalate it to. A card payment to a licensed operator is easier to dispute, and many banks let you switch on a gambling block that stops gambling payments altogether.

We have removed the full currency lists from older versions of this review, because we could not confirm which methods the site supports today.

7. Where JustBit Is Not Available

When we reviewed JustBit in 2023, its terms excluded players from the United States and its territories, France and its territories, Spain, Portugal, Israel, Malta, Ukraine, Curaçao and several other countries. We could not read the current terms, so that list may have changed.

The safest assumption is simple: if an operator is not licensed by the regulator in your country, it is not a legal option for you, whatever its own terms say. Trying to get round a block, for example with a VPN, can breach both the casino’s terms and local law, and offshore casinos commonly treat it as grounds to void winnings.

8. JustBit Customer Support and Complaints

JustBit offered live chat and email support in 2023. We have removed our own past chat test and the third-party ratings from older versions of this page, because they cannot be checked today and some review sites earn commission from the casinos they rate.

Support staff can answer questions, but they cannot give you independent protection. At a casino licensed in Great Britain, a player with an unresolved complaint can take it to an approved Alternative Dispute Resolution provider, as the Gambling Commission explains. A player at an unlicensed offshore site has no such route.

JustBit Review: What It Means for Players

Because we could not confirm a licence for JustBit, and because it is not licensed in the UK, the US or the other regulated markets we checked, playing there would mean:

• No local protection. Your regulator’s rules on fair terms, player funds and advertising do not apply.
• No independent dispute route. A refused withdrawal stays between you and the operator.
• No self-exclusion link. GAMSTOP blocks only gambling sites licensed in Great Britain, and national schemes elsewhere work the same way.
• Tax still applies. In the US, for example, the IRS says gambling winnings are fully taxable and must be reported.
• Possible blocking. Mirror domains get blocked, and banks often refuse payments to unlicensed gambling sites.

The regulated route is to use operators licensed in your own country. Check your national regulator’s register first, for example the UK Gambling Commission register or the Malta Gaming Authority licensee register. Match the company name and licence number in a site’s footer against the register before you sign up anywhere.

How to Check a Casino Licence: JustBit and Others

Our experience with JustBit shows why licence checks matter. You can do one yourself in a few minutes:

1. Find the company name and licence number in the site’s footer or terms. If you cannot find them, or the site will not show them, treat that as a warning.
2. Search your own country’s regulator first. If the operator is not there, it is not licensed where you live.
3. For a Curaçao licence, check the Curaçao Gaming Authority’s register and its enforcement register for revoked licences.
4. Check that the web address you are using is the one the licence covers. Numbered mirror domains are a red flag.

9. JustBit Review: Conclusion

JustBit is a casino and sportsbook that launched in 2021. The company our earlier review named as its operator does not appear on the Curaçao Gaming Authority’s current register, the site now runs on a numbered mirror domain, and we could not read its current terms. It is not licensed in the UK, the US or the other regulated markets we checked.

For those reasons 99Bitcoins does not recommend JustBit. If you want to gamble, choose an operator licensed by your own country’s regulator, where your age, your money and your complaints are covered by local rules.

Gambling should only ever be entertainment. Set a budget, never chase losses and take breaks. If it is becoming a problem, Gambling Therapy offers free, confidential support worldwide, and in the US the National Council on Problem Gambling runs the National Problem Gambling Helpline, 1-800-MY-RESET (1-800-697-3738), which is free, confidential and open 24/7 by call, text or chat.

FAQs

Is JustBit licensed?

We could not verify a current licence. The company our earlier review named, Casbit Group N.V., does not appear on the Curaçao Gaming Authority register dated 2 October 2026, and the site’s security check stopped us from reading its terms. JustBit is not on the UK Gambling Commission register, and 99Bitcoins does not recommend it.

Is JustBit legal in the UK or the US?

No. JustBit holds no UK Gambling Commission licence and no US state licence, and its earlier terms excluded the United States. Online gambling in those countries is legal only with locally licensed operators, so players there should use a site listed by their own regulator.

Why does justbit.io redirect to justbit4.io?

The original domain now forwards to a numbered mirror. Offshore casinos often use mirror domains to stay reachable when an address is blocked. It is a sign the site operates outside the licensing systems of the countries it serves.
