If I hear of match fixing, I will stop because I have known already that it is a scam.
If it is a telegram bookie, I will stop and delete the scammer from my telegram. I do not gamble on telegram.
We can see some people that wants to try something like this or something similar on this forum, referring us to add them on telegram. From their approach on this forum, you will know that they are scammers.
It's not a telegram bookie.
It's a fully fledged website that looks somewhat realistic, but the "fixed" match advertised by the telegram group is actually not a real match, and no matter how hard you search for it you will always come up to that specific bookmarker website, which happens to be a fake bookmaker.
You will deposit, bet on the exact score given by the telegram group, hit some crazy multiplier when the fake match supposedly finishes... And then you will never be able to withdraw.
It's actually a well polished scam. Some of the team names I looked up were actually real teams, they had just swapped the league and day of the match. For example for a real match of Team A and Team B on a Tuesday they would say
Team A vs. Team B (U23 league) on a Monday. This seems entirely possible as actually sometimes U23 leagues can have similar schedules with regular leagues. But The league they are talking about is actually always nonexistent. But I could even see someone kidna experience falling for this because just by Google searching you can't definitively find out that these teams don't exist.
