This is no based on proven facts. It is based on personal experience and preference
I have been gambling for the past 2 years on sports , specifically soccer and i find it more better than Revshares and HIYPs, It's not an easy thing to do but ,it's the same as trading on a volatile market. It's either you win big or lose big ,however in my case i have mastered eliminating house edge and increase my odds of winning therefore winning. Now with Bitcoin online bookies/Betting sites i can transfer a small amount of satoshis then choose the matches i'm betting on right after statistical analysis. Predicting a game of soccer is not easy ,but one can capitalize on factors affecting the overall outcome of the game.
Most Major soccer leagues will be opening Mid-August and wow , so much Bitcoin/money to be made...
