If you’ve ended up on this page, chances are that you are looking for one that’s just right for you and that’s exactly why your Betting Fellow is here to guide you in the right direction. Depending on your aspirations and the current country that you are in, there are a few factors to take into consideration before you actually decide on a particular betting venue.

Site Reputation

This is considered to be one of the most important things in the online betting industry. Finding a reputable option can save you a lot of time and money in the future, and sparring a few minutes in order to do the needed research is a far bargain. A reputable website puts a lot of effort into protecting its members and will do everything to keep your personal information safe and secure.

Customer Support

Customer support represents your insurance policy if anything is to go wrong. The best websites are the ones which support you’ll never use. If the time comes when you do however need it, using the online betting site with the best service hours, easiest contact options, and overall helpfulness should be a priority.

Withdrawal Limits and Timeframes

All betting sites offer a range of different payment methods for withdrawals, and each is subject to their own processing times. Usually, it’s more the method you use, not the site, which limits how much of your money you can get out, and how quickly you can do it. Some bookmakers tend to delay payments deliberately as they might expect of you to change your mind during the process. Bear in mind that each option may differ depending on the country in which you live.

Competitiveness of Odds

If your goal is to make money, finding the online bookmakers with the best odds and smallest margins can heavily impact your profits in the long run. For that reason, doing your research is really important, and guess what, we are here to help.

Betting sites FAQ

Although this category tends to vary from time to time, there are a few all-time fan favourites. The most popular online betting sites include Bet365, William Hill, Ladbrokes and Pinnacle. These bookmakers are some of the longest-running on the market and thus have the most experience. Punters are aware of their enviable reputations and professional and fair business-running.

Additionally, they offer the best sign-up bonuses and promotions. Therefore, these bookies have remained the most frequented online betting sites in history. On Betting Fellow, you can read unbiased and thorough reviews on all of these bookmakers.

What is the most reliable sports betting site?

According to most online bettors, some sports betting sites are more reliable than others. There are multiple aspects when granting the site this stamp of approval. A trustworthy bookmaker has a long history of fair payouts, a wide array of payment methods and short withdrawal times. A good reputation is built over the years. Some new online betting sites seem promising, but it takes time to prove oneself. Based on the listed criteria, a limited number of bookies have passed the test. These include, but are not limited to Bethard, Unibet, Betway and Betsson.

What is the safest online sports betting site?

There is not a single answer to this question. There are a few selected reputable bookmakers who show off utter safety and security. They guarantee the two crucial aspects in a few ways. The first one is licensing. Strict regulatory bodies like the UK Gambling Commission (UKGC) and the Malta Gaming Authority (MGA) should back the site up. This proves professionalism. Secondly, the utilisation of the SSL (Secure Socket Layer) encryption protocols is recommended and desirable. Thirdly, customer feedback should be positive and optimistic. Based on these standards, the safest bookmakers are Ladbrokes, Coral, BetWay and Bet-at-home.

Which betting sites do cash out?

Cash out is a convenient online betting feature that many players appreciate. The basic principle behind it is that you have closer control over your betting experience. Cash outs let you take your profit early if you see your bet coming in. Additionally, you can grab some of your stake back thanks to it. If you no longer see eye to eye with your initial bet, you can change your mind. A change of heart is a natural occurrence in online gambling. Therefore, the cash out functionality lets you go with your gut feeling. The leading bookmaker sites that do cash out encompass Paddy Power, Betfair and BetFred. Cash outs are available on single and multiples on an ample section of sports and markets. There is also the partial cash out.

What is the biggest betting company in the world?

According to the latest 2019 research, a couple of prominent sports betting companies lead the way. Based on successful operating and satisfied clients, 888 Holdings and GVC Holdings are the biggest betting firms in the world. The GVC Group owns Ladbrokes and Coral Group.

Who are the biggest bookmakers?

The so-called “Big Three” among bookmakers are William Hill, Ladbrokes, and Coral. They have been in the business the longest and successfully operate even today.

Where can I bet on sports online legally?

Whether betting on sports online is legal in your country depends on the country’s regulations and laws. Henceforth, there is no unique answer to this enquiry. However, a vast majority of countries and states worldwide allows online gambling. This also includes online casinos. Nevertheless, the United States has struggled with allowing this form of entertainment. Right now, only a small number of states permit these services. These are Nevada, Oregon, Montana and Delaware. You can bet on sports online legally at BetOnline.ag, Intertops and BetWay, to name a few.

How many bookies are there in the UK?

The United Kingdom is one of the most prolific online betting markets in the world. Therefore, it comes as no surprise that the largest numbers of bookmakers are based right there. In September 2018, there were exactly 8,406 betting shops in the country. William Hill owned 2,298 of those, whereas Ladbrokes was in possession of 1,894 bookmakers’ shops. Other notable businesses included Betfred and Gala Coral Group.

Are betting sites safe?

To answer the question simply, if the bookie owns a licence, it is safe. You can check that on the bookmaker’s website, or here in Betting Fellow bookmaker reviews. Supervisory organs check and examine the premises based on numerous criteria. If the said bookie passes the test, a licence is granted. However, before that happens, they have to prove they are safe and secure. Additionally, they have to run on a reliable platform and utilise required protocols.

Which betting company gives the best odds?

You are a passionate punter, and you want the best odds and margins delivered to you. In terms of the latter, Pinnacle is the absolute leader. Pinnacle offers a 2% margin, which is about as low as it gets in the world of bookmakers. They promote the reduced juice approach and are thus fan favourites. However, the best and most competitive odds are also offered by BetWay, 888 Sport, Bet365 and William Hill.

How do I place a bet online?

If you want to place a bet online, read on. You are in the right spot. The first thing you need to do is choose your preferred bookmaker. Betting Fellow can help you do that. Check out our Betting Fellow bookmaker reviews for more information. We examine and test popular bookies, and then we review the best of them. The next step is to register an account with that bookmaker. Provide your basic personal data, verify your email address and log in on the website. Find the bet slip on the premises. This is where all of your bets will be. Check out the selection of sports markets and choose the one you want to bet on. Type down your stake and simply click on the ‘Place Bet’ button.

Can bookies refuse to pay out?

Theoretically speaking, a bookmaker can refuse to pay out winnings. However, this is rare, and when it does happen, it is completely legal and justified. Let us clarify. In certain cases, some circumstances prevent a bookie to pay out. If the bookie suspects that there has been illegal activity involved upon bet placing, it can refuse to pay out. There is no legislation to enforce betting debts. The same goes for online casinos.

Can bookies ban you?

Bookies can ban you and prevent you from betting on their website. This can happen for a number of reasons. If the bookmaker suspects you have been using a forbidden strategy to win your bet, you can be banned. Keep your eyes peeled for those Terms & Conditions at all times. For instance, some bookies do not allow arbitrage betting. Arbers will be banned at such places. Others, like Pinnacle, for example, will have not have arbers gubbed. Additionally, if your bets are repeatedly oddly specific, the bookie might find you suspicious and ban you. To avoid this risk, spread your bets across several bookmakers, consider betting on “round numbers”, and place your fixed odds bets early.

Do bookmakers ban winners?

There is a common misconception that bookies will not bother banning winners. The truth is that bookmakers indeed ban some winners. This can happen for a couple of reasons. Bettors who have extremely long winning streaks are often considered suspicious. Bookies then check their activity, and if they find anything illegal regarding their gambling, they can deprive them of their winnings. As with the previous answer, follow our free instructions and advice. Stay on the safe side if you don’t want to get banned from a sports betting site.
