If you know someone's going to wait a long time, you could go early and you have a better chance of getting the bonus.
The bolded part is wrong. If someone managed to cash out at the higher multiplier than those who cashout at the earlier multiplier will not get the bonus
No, the bolded part is correct. If someone cashes out at high multipliers, all you have to do is cash out at 1x with the same size bet and you'll scoop a 2.x% bonus most of the time. That's what "better chance" means. It won't be every time, obviously, but if the other person is frequently cashing out >1.97x, you'll get the bonus enough of the time to make the play +ev.
