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...
well even playing dice is better than HYIPS in my opinion , but don't agree about rev shares cause I know 3 solid sites that they are really doing good
in general gambling on sports is tricky as hell , most people think that they are doing well on it but more than 90% fail so bad
as long as you are tracking your results and made more than 1000 bets with profit I think you have beat the game
for me I find poker better than anything else
i can't say much about poker , i hardly play it , only when i visit the casino , but my favourite casino game is European roulette and i dont play it online because online poker , blackjack roulette is not different from slot machine. its algos
