This is dangerous if they show up some fake winning result since there would be a lot of guys will be interested to try what the guys do to see if they can also get the same large winning result.
Do not believe in everything we watch in the internet. That's why people should educate themselves about such gambling stream or gambling in general. As I said before in this thread, if there are many people get attracted to try because of big win shown in the gambling stream and they believe that will get the same big win but they do not aware that gambling is all about luck or do not know that losing chance is big then it is their own fault.
