I have stop using autobet on dice. always end up getting screwed without my knowledge. manual mode is much profitable but you need to control yourself specially on the Dice
neither manual nor autobet method can be profitable in my opinion
Thats not really opinion, its a fact. The only difference between manua and autobet is speed of losing your money.
gambling is created to make you fail and it can not be profitable in a long run
This is false though, all depends on which game we are talking about. Your are not always playing against the house, house can just position himself as a rake taker, and he would not care if you win or lose, therefore you can win by simply taking a money away from other players (and "sharing" profits with the house by giving them rake).
And in some cases, you are playing both against the house and other people (sport betting), and the house does not have the overwhelming advantage there. It has it, for sure, due to the margin, but its not unbeatable. After all, its just people who are setting the betting lines, they are not all knowing perfect beings with complete information about everything.
