Nitrogen Sports has not vanished. Its old address, nitrogensports.eu, now forwards visitors to mynitro.io, trading as Nitro. This looks like a rebrand, but independent reviews suggest the site may now be run by different people. No sister site is confirmed, so we list real crypto betting alternatives instead.
What happened to Nitrogen Sports
Nitrogen Sports launched around 2013. It became known as one of the first Bitcoin-only sportsbooks, with a casino and a poker room bolted on. It ran for close to a decade with a solid name among Bitcoin gamblers.
The site did not just quietly move house once. We traced two hops. In July 2022, the old nitrogensports.eu platform stopped operating and pushed players toward a new domain, nitrobetting.eu, described at the time as an “enhanced” version of the same service. Today, that nitrobetting.eu address also forwards on again, this time to mynitro.io. In other words, nitrogensports.eu and nitrobetting.eu both now land on mynitro.io, the site trading as Nitro.
Nitro’s own “about” page says it has run for “almost a decade” and calls itself the continuation of the old Nitrogen Sports brand. That is the company’s own story. We could not find an operating company name or a gambling licence number anywhere on the site to check that story against. That absence matters, because a licensed operator normally states who it is.
Older press mentions show Nitrogen Sports was once linked to a company called Ideal Media Incorporated, with a manager named in industry coverage around 2021. Independent reviewers who have tracked the site through both name changes say it now looks “highly likely” that entirely different people are behind it today. We were not able to confirm who currently owns or runs Nitro. Anyone who tells you with certainty who owns it now is guessing, and so are we — the honest answer is that it is unclear.
What happened to old accounts and money
This is the part that matters most if you have an old Nitrogen Sports account. We looked for evidence that balances and logins carried across the two domain changes, and the picture is not reassuring.
On review sites, both the old “Nitrogen Sports” listing and the current “Mynitro” listing carry a poor score, close to the bottom of the scale, built almost entirely from one-star reviews. Recurring complaints include accounts becoming unreachable after a domain switch, players saying they felt “rug pulled,” and withdrawal requests left pending for months. A public complaint filed in early 2026 described roughly 193 mBTC (about 0.193 BTC) stuck for six months after a last successful payout in August 2025, with several other players describing similar delays adding up to more than a full Bitcoin between them. Support replies in these threads reportedly blamed “domain migration issues” or database problems.
We did not find a clear, official statement from the operator confirming that every old Nitrogen Sports balance was honoured in full on the new domain. Some long-standing users say the newer site is simply worse than the original. If you still hold funds on an old Nitrogen Sports login, treat any balance as at risk until you have tested a small withdrawal yourself and it has actually landed in your wallet.
Is there a real sister site here
A sister site means two gambling sites share the same back-end platform, the same cashier, or the same owner. It does not mean two sites simply look similar or both take Bitcoin. Plenty of crypto casinos share a design template or a game supplier without being connected in any way that matters to a player.
By that plain rule, nitrogensports.eu, nitrobetting.eu and mynitro.io are the closest thing to sister sites here, because all three addresses now lead to the same platform. But that is really one site that has changed its name twice, not a family of separate sister brands. We looked for any other site sharing Nitro’s cashier, software, or a named parent company, and found none. A gambling industry database that lists company connections for well-known operators shows no listed affiliate or sister brand for Nitrogen Sports at all.
So the straight answer is: no genuine third-party sister site is confirmed for Nitrogen Sports or Nitro. If you see another site claiming to be its sister, treat that claim as unverified until you can point to a shared owner or a shared platform, not just a similar look.
Alternatives worth checking instead
Since we cannot point you to a confirmed sister site, here are other crypto-friendly sportsbooks and casinos that a Bitcoin bettor coming from Nitrogen Sports might look at. These are separate companies with their own ownership. They are not sister sites of Nitro — we list them only because they serve a similar kind of player.
- Cloudbet — a long-running crypto sportsbook and casino that also started out crypto-first, with sports betting, casino games and esports markets.
- Stake — a large crypto casino and sportsbook with a wide range of games, though its identity checks have tightened over the years.
- BC.Game — a crypto casino and sportsbook that accepts a wide range of coins alongside Bitcoin.
- Sportsbet.io — a crypto-focused sportsbook with a casino section, aimed mainly at sports bettors.
Check each site’s own current terms before you sign up or deposit. Identity and verification rules change often in this industry, so do not assume any of these sites works the exact same way Nitrogen Sports once did.
Is Nitro still Bitcoin-only with no ID
Not in the way it used to be. Nitrogen Sports was famous for taking Bitcoin only, with no identity checks at all for most players. Nitro has moved on from that.
Nitro’s own help pages say you can open an account with just an email address, and it does not ask for identity documents up front. But it also states plainly that it “reserves the right to request a KYC when deemed necessary.” That is not a no-ID guarantee. It is a site that can ask for ID whenever it decides to, which most often happens around a withdrawal.
On the crypto side, Nitro is no longer Bitcoin-only either. It now accepts several cryptocurrencies beyond Bitcoin, including USDT, BNB, USDC and Litecoin. So a returning Nitrogen Sports player should expect more coin choice, but less of the old no-questions-asked feel.
Sports, casino and poker on Nitro today
Nitro keeps the same three-part offer Nitrogen Sports was known for: a sportsbook, a casino, and a poker room, all under one login and one crypto balance.
The sportsbook covers the usual major sports — football, basketball, tennis, esports and more — with standard bet types like moneylines, spreads and totals. The casino section carries slots and table games from third-party studios, the kind of line-up you would expect from most crypto casinos. The poker room is still listed as a live product on the site, and it is still described as separate from some casino bonus terms, so it looks like poker has carried through rather than being dropped.
We could not verify player numbers or table traffic on the poker side. A poker room is only worth joining if there are enough players at the level you want to play, and that is something you can only judge by looking at the live tables yourself.
Payments and withdrawals
Deposits and withdrawals both run through crypto, not a bank card or bank transfer. That part has not changed from the Nitrogen Sports days.
What has changed, based on player reports, is how quickly and reliably withdrawals actually pay out. Nitrogen Sports built its name partly on fast, simple Bitcoin payouts. The reviews we found for the current site tell a different story, with repeated reports of withdrawal requests sitting for weeks or months, and in some cases far longer, before anyone gets paid, if they get paid at all. Given that pattern, treat any large balance with caution. Start with a small deposit, make a small withdrawal, and confirm it actually clears before you trust the site with more money.
Bottom line
Nitrogen Sports did not close down quietly. Its old domain now forwards to mynitro.io, trading as Nitro, after passing through a middle name, nitrobetting.eu, along the way. The site still offers a sportsbook, a casino and a poker room, and it still runs on crypto rather than cash. But it is no longer strictly Bitcoin-only, it can ask for ID when it chooses to, and there is no operating company or licence number on show to check its claims against. Independent reviewers cannot confirm the current operator is the same team that built the original site’s reputation, and recent player reports about slow or missing withdrawals are a genuine warning sign. We found no confirmed sister site for Nitrogen Sports or Nitro. If you are weighing whether to trust it with your money, that lack of a clear, checkable owner, combined with the withdrawal complaints, is the single fact to hold on to.
