Now my question is; if gambling on single bet is that reliable why not many people becoming a millionaire or even resigned from gambling because they could have ended up accumulating the amount they wished to have in their possession.
Single bets aren’t reliable as well as accumulation bets. No bet is reliable actually but, you take less risk by gambling on a single bet when compared with accumulation bet. In accumulation bet, you have all the possible scenarios you consider across several games while, on single bet, you’ve got just a single game to consider these scenarios. Having to gain it all on a single bet means, you’ve got to take risk with the odds and stake, you don’t need to stake too high else, you could loss just as much.
