I’m not sure what this article trying to point out because the author is assuming that streamers should use real money to be called as legit streamers while a simple streaming of gambling even using play money can be called a legit streamer because they are streaming. They are not faking their stream and it’s up to the viewers if they will take seriously what the streamer saying.
So they mean that the streamers should use their own personal money to gamble and stream and not use the play money? What could be the intention of this wish? They want the streamer to lose his own money too which streaming for the viewers? This is just a strange wish by the author of that article.
I would just say one thing if the streamers are producing fake streams, still they are popular, meaning that people are happy seeing those streams and they like the content which is produced by those streamers.
