Also, I am just wondering can a delay of 8-9 seconds are really beneficial for the gamblers? Unless someone is a professional gambler, it is usually very difficult to make decisions within this timeframe.
It takes 4-6 seconds to make a live bet on a European sports bookie. I think this time is 2-4 seconds on Asian bookies. So if his stream is 8 seconds ahead, it's a pretty big gap. It sounds too good to be true and my gut feeling is saying it's a hoax, but I will give him the benefit of the doubt.
