Celebrities are already rich and they are betting maybe for fun without doing any research or just picking as they please, and that's a possibility. So I think celebrities won't regret it if the bet fails.
and I declare that I will not be influenced and will not follow it, I prefer to bet on the results of my personal choice and research, lose or win I have my own satisfaction and my own results without any encouragement from celebrities or anything.
but for today's younger generation it will most likely follow, because I see many young people who really idolize celebrities who are very excessive and also too fanatical.
Social media has made matter worse by publicizing whatever these celebrities do. However, most of the times when celebrities gamble openly, it could be for advert purposes. I don't think any celebrity wants to be associated with the context of being an addicted gambler.
Every gambler should gamble at his or her own pace, not by being voluntarily or involuntarily influenced to follow through. Most movies portray gambling scenes with an interesting theme song or characters, I wonder if the coy is to make gambling appeal graciously rewarding.
For my favorite celebrity, I do not however have the kind of resources they possess, therefore, doing as they do, simply for reward or fact of doing as my celebrity does is not even feasible.
