Coldbet – Review and Test of the BetB2B Sports Bookmaker

Towards the end of 2025, Coldbet first appeared on the digital sports betting market. Behind the offering is Game2Net B.V.; regulation is officially handled via a Curaçao license. Technically, the bookmaker is based on the BetB2B platform, a solution originating from 1xbet. The betting program covers more than 50 sports and appeals especially to users for whom fast transactions matter: crypto withdrawals are processed in under half an hour.

For players from Switzerland, Austria and Germany, Coldbet – like several other BetB2B providers – is not directly accessible via the original main address. However, the bookmaker provides an alternative access URL.

Website and Language

Coldbet is clearly internationally oriented: nearly 50 language versions are available, including a cleanly localized German version. Account creation proceeds without major hurdles, either via mobile phone, email address or social networks. In terms of website structure, Coldbet clearly takes cues from the well-known 1xbet style, making the navigation quickly understandable. On the left-hand side, top events and favorites appear first, followed by the extensive sports betting offering.

The search bar in the top right allows players, matches or entire leagues to be found specifically. Directly below are expandable menus for frequently used sports such as basketball, football or tennis, which can be expanded as needed. On smaller screens, however, the interface can feel somewhat cluttered in places. The respective betting options are then displayed; the “all markets” button opens all odds for an event.

A small chart icon leads to additional information, such as statistics or odds history. Especially for football bets, the level of detail is high, though many details are only available in English. The betslip sits on the right-hand edge and can be hidden if needed. Directly below it is a chat icon providing access to live support.

Betting Offer

As mentioned earlier, Coldbet uses the powerful BetB2B platform, which enables an enormous betting portfolio with over 50 sports. More than 5,000 events are available per day. The offering covers well-known disciplines like basketball, football, ice hockey, tennis and volleyball, but also rarer sports such as pickleball, padel, water polo, fencing and greyhound racing. For top football matches, over 1,200 betting markets can be available; even smaller matches still offer at least 500 options. Alongside classic bets on win, loss or number of goals, there are numerous special markets, for example on player actions, throw-ins, offsides or corners. Creative bets such as “How long will the match stay tied?” or “Goalkeeper sees red” round out the program.

For fans of German football, coverage is especially broad: a total of 20 German leagues including the Regionalliga are listed. Even at these levels, more than 500 bet types are often available per match, which is remarkable for this tier. Other sports are also well served: basketball offers around 50 betting options per game, tennis around 20.
Furthermore, Coldbet is not limited to sports. Bets on movies, TV series, shows, music, political events and even the Nobel Prize are also possible, underscoring the provider’s enormous variety.

Live Betting

In the live betting segment, Coldbet offers more than 30,000 real-time events per month. The payout ratio here ranges between a solid 93% and 95%. Especially in major football leagues like the Premier League, Bundesliga or Serie A, popular markets like Over/Under or 1×2 frequently sit at stable odds around 94.5%. For football matches, over 400 live betting options are available, including special markets like “Next corner” or “Next goalscorer”.

For live betting on basketball and tennis, the payout ratio is somewhat lower than pre-match, which is partly offset by many handicap and special markets. The live section is clearly laid out and allows quick access to ongoing as well as soon-to-start matches. Via cash-out, either full or partial, placed bets can be flexibly hedged right up until shortly before the match ends. Also very useful is the “Multi-Live” feature, which lets you follow up to four matches simultaneously on an individually assembled page. Previews of upcoming live events are also available.

Betting Odds and Limits

Coldbet unfortunately doesn’t reach 1xBet’s odds level, which is one of the provider’s clearer weaknesses. Bookmakers on the BetB2B basis currently tend to work with lower values. While 1xBet often offers odds above 98% for major football and US sports events, the average in this area is around 95%. This value is still reasonable and in line with the industry average. Also advantageous is the 5% betting tax not being charged, making tax-free bets possible.

The bookmaker is also generous with stake limits. For Champions League matches, five- and six-figure stakes are possible. In addition, so-called string bets are possible: after placing the maximum stake on an event, the same bet can be placed again at a lower price.

Deposits at Coldbet

Besides PayviaBank (€5-499) and GooglePay (€5-2,000), Coldbet focuses mainly on cryptocurrencies for payment methods. For crypto deposits, options include QTUM, Dash, Ethereum, Bitcoin, Shiba Inu, Cardano, Binance Coin, Dogecoin, Polygon, Tron, Digibyte, Ripple, Solana, Cosmos Atom as well as the stablecoins USDC, Tether and DAI – altogether a solid selection.

The respective minimum amount is important for crypto deposits. If it is not met, the payment may be lost and not credited to the account. It’s therefore recommended to always leave a small buffer above the minimum limit. Depending on the method chosen, the lower limit is between 10 and 30 USDT.

Withdrawals at Coldbet

Withdrawals at Coldbet are only carried out via Mastercard, Visa and cryptocurrencies. Before the first withdrawal, all personal details must be fully completed in the profile. In addition, both phone number and email address must be confirmed.

For digital currencies, the limits differ significantly depending on the coin and network. With USDT on Solana, withdrawals are possible from as little as €0.50, while for Bitcoin a minimum amount of €342.34 applies. The maximum, however, is significantly higher, reaching up to €68,467.88. For USDC on Solana, withdrawals start at €4.47; the withdrawal limit here rises to up to €645,512.60.

Overall, the withdrawal options appear strongly geared toward cryptocurrencies. On the plus side, Visa and Mastercard are also available. Based on past Coldbet experience, processing happens quickly: no additional documents were requested during testing. Withdrawals usually arrive after just 5 to 30 minutes.

Support

Coldbet offers round-the-clock customer service, relying primarily on a directly integrated live chat on the website. Questions are often answered quickly this way; based on experience so far, German-speaking support is frequently available. A contact form is also available for technical inquiries. Email support is offered as well, though it’s better suited to less urgent matters. The help content explains important points about payments, bonus rules, account, betting and verification. The structure feels functional, even if some answers are fairly brief. Overall, support leaves a solid impression, as fast help, permanent availability and understandable examples help both beginners and experienced users make well-informed decisions.
