Many experts will tell you that the maximum reward is gained from finding bets that offer real value. For example - bookmakers love long ACCAs simply because it is so hard to generate a consistent profit from them so steer clear of such bets.
If by ACCAs you mean parlays or a bet consisting of multiple choices it can give you the maximum reward but this happens only a few times and you need a big amount of luck. I have seen people though win a lot of money from these parlays when they happen.
I have some fan pages in facebook which I follow and they like to place accumulator bets, they don't hit it almost never but there are a few cases when they do and the reward is something like 10 Euros for about 4000 Euros. I just follow their bets with 1 Euro when I don't forget to do so. Never hit one though during all the time I have followed them but I am not a regular follower.
Yes, real value! Do you mean bonus? Which platform are you using? How many percent bonus offers do you get? I am using vegascasino.io I love using it because It has low restrictions and also most of the time I do get the bonus whenever I fund my accounts. How long have you been betting? Maybe you can show me some tricks! A friend of mine Loves betting playing blackjack games. Just wondering how he becomes successful all the time just that some of these guys won't show you their tricks. How many percent bonuses do you get? I do get a 100 percent bonus from vegascasino.io. One exciting thing about gambling is that you seem to be very happy when winning but gets frustrated whenever you lose your game.
