Allowing streamers to convince you to gamble is a dumb thing to do. Nobody should tell you to gamble when you don't want to gamble previously. The streamers can give you options on which game you'll want to play and you try them out depending on your abilities and to have some fun as well. Streamers aren't promoting fun as they claim to do, they're fueling addiction because all they do is for their paycheck and not for your interest.
They're acting as influencer to try in influencing you to try out the new games they're promoting which they were paid for which the games aren't always that interesting of a game to bet on and they too get to audiences that weren't supposed to see the content because of their immaturity. Steamers are only there for the likes and cash.
It is dumb after you try it out yourself and you find out that it was all a lie, winning isn't always easy like those streamers make it seems.
You call it dumb because people will surely lose money, but will it be dumb if the majority are getting positive results? I don't think so.
A beginner or newbie will never know, until they give a try and find out the truth themselves, and if you don't give something a try how will you find out if it will work or not? We can judge like this because we already know how gambling always turn out.
