As opposed to what? Using some "strategies" like the martingale (please do not do this, ever) and fibonacci? They don't particularly have as great results as going all in either. I would personally rather choose to bet it all on one single bet rather than drag it out and increase my risk of ruin. There's always the possibility of going positive in either scenario, but when you go all in you get an instant reward or loss. No use in waiting when the chances are around the same.
