I'm fully aware that match fixing exist but I've also noticed that most of these online punter use that as an opportunity to scam people, they feed greedy gamblers with the mentality that they got fixed games and lure them into their so called VIP groups either on Telegram or WhatsApp where they'll pay to get the games, it's a trap and people should avoid punters like that when they come across them on the media, especially on Twitter.
Sometimes scammers do clone the account of some punters without Vip groups on Telegram and you'll be suprised how easy they lure people into paying for what they call sure or fix games. In my own point of view, you can't beat the house so there's no such thing as sure games, what those scammers do is select 3 to 4 odds with a good potential of winning and give to their victims on first trial and ask them to stake very high, that would lure them back into paying for another game if it works and if it doesn't your money is gone, people should take note and avoid paying for VIP games.
You're very correct,you see a friend of mine have been a victim of this weak schemes.The first attempt is usually what they use to trap the mindset of so many gamblers.
It has becomes a full medium for these scammers to gain more followers to themselves, meanwhile they offer gamblers fake predictions.They'll make sure your first try with their game odds and predictions are worth it so they initially gain your trust right from that spot.
Scammers are obviously real scammers and their schemes needs to be studied to avoid continuous scams and mistakes.
