That is a weird selection of options for your poll as they cover so many different angles. People who own casinos will generally be super rich from setting up a business and stay away from gambling unless it is purely for entertainment purposes, they're just likely to see it as a profit center instead of an outlet for fun. You have another option that discusses setting up a cryptocurrency casino review site, and it makes a little bit of sense but even then - you might not gain much from gambling money away because games can change and you can accurately describe most functionality without spending anything at all. I would guess that most people are seeking to win the various large jackpots on offer, surely?
