Diamond Sportsbook International (DSI) is another brand that had an early presence in the industry. Providing reputable betting services since 1998, DSI has become a trusted and preferred destination for betting on all types of events, matches and games, including European, International and US sports. You will find lines for both professional and collegiate leagues, as well as amateur leagues in some cases. Their software is a proprietary interface that is regularly audited through agents of the OSGA offshore gaming advisory board. In addition to sports betting, DSI is licensed and regulated through Costa Rica to also provide an online casino, poker room and race book. Their features include live betting options and a savvy mobile betting application as well. DSI's long time presence in online betting has allowed them the luxury of building up an extensive sportsbook platform that provides a significant number of betting lines, wagering options and features for both casual and professional sports bettors.

The sign up bonus at DSI is a generous 50% match up to $300 on your first deposit. To qualify for the bonus, your deposit must be $50 or more. This bonus carries a 10x rollover, and restrictions include Moneybookers or NETeller deposits. In addition to their welcome bonus, DSI offers BetPoints in which you can earn cash back on every bet you make, a $2500 reload bonus, and an 8% daily cash back when betting on horses. They seem to work pretty hard to ensure there is some type of offer available to you every time you visit. Their bonus offers are dated, so be sure to check out the promotions tab on their website to see the latest offers and terms for claiming the bonus or free play offers.

Diamond Sportsbook International has been operating at the top tier of the sports betting industry long enough to have acquired a very strong following. Their player base is significant, and they are known for professional, high quality services that support an enjoyable and sophisticated betting experience. They take the time to develop relationships with their customers and go out of their way to keep special promotional offers and betting lines, odds and services fresh and welcoming. DSI creatively provides an ideal environment for sports bettors with services and rewards that keep them coming back for more.

Sports bettors enjoy that DSI offers more than just the primary leagues in their betting lines. They also include the sports that aren't quite as mainstream, such as rugby, tennis, golf and surfing. They also cover martial arts, motor sports, cricket, golf and options for betting on entertainment or politics. These last two options provide those who enjoy wagering but are not die hard sports fans a nice platform to become in engaged in trustworthy online betting.

BetDSI has developed their banking suite to effectively support both US and International customers through a nice selection of banking methods. Their payment methods include Visa, American Express, MasterCard, Bitcoin, Person2Person services such as Western Union and MoneyGram, Bank Draft, Bank Wire and EcoPayz. Options for cashing out include Western Union, MoneyGram, Bitcoin, Bank Wire, Bank Draft and Prepaid MasterCard. You can acquire the prepaid MasterCard by filling out an application for the card through the DSI cashier. The banking suite at DSI employs the highest standards in security protocols, including advanced encryption technology for keeping all of our personal information and transactions completely secure.

DSI is one of the oldest and most reputable sports betting sites available in 2015. One thing that should interest potential players is the fact that DSI offers much higher withdrawal limits compared to other sportsboooks. If you run your balance up to $40K, you can cashout the entire balance. Other sportsbooks only allow players to cashout much smaller portions as they impose weekly limits. For me, this is is one of the deciding factors when it comes to picking a sportsbook.
