Love of gambling (or gambling addiction) is not a matter of money AFAIK.
I must agree with the above in that the price of BTC may not put others off from gambling at all because gambling to them is nothing more than just that. One could argue that you could even get lucky, and while we know that the odds are low it won't stop people from trying.
So I think when you have something that you do everyday you can't suddenly stop, addiction makes it even harder and some may find it even more thrilling. Bottom line is that people are people, and price/money is irrelevant when it comes to feeding addiction.
