Casino Bonus Questions

[evanski]

Sorry if these are asked regularly, I did poker around a bit with the search function and on Homer's site and couldnt find the answer.

1. If, while doing a casino bonus, you lose all of the bonus money but not your stake, and have not yet completed the wagering requirements, can you cash out? (I assume the answer is no).

2. I havent put a whole lot of thought into this, but it seems to me that the EV of a bonus is independent of wager size (although increasing one's wager certainly increases the variance). Is this true?

Thanks.
