Finding Value Bets (know your sports, study hard, money management - basically being a pro!)
This is what I do. It is not as easy as it sounds but I am able to make some profit since I am fun of football and know which team to bet on.
It is a little profitbut at least am having more fun when watching football matchs.
I used to play dice in online casinos and apply the martingale technique. In the beginning, I had some profit but as the time went by I started losing and losing and I wasn't able to cover my initial bet.
Now I am trying something like the same but differently. I pick a big football club and I bet that it will lose. If I lose my bet, I double it and so on.
I never liked the martingale technique, besides, most of the casinos consider it as cheating.
