Don’t send money to anyone because of sure fixed matches, no prediction is sure they are lying to you and those wins you are seeing them post is not real so be careful, just predict matches yourself because gambling is 70% luck.
I don't see the logic in why they will have to invite people to subscribe for a small profit if there are fixed matches that they will be relying on, when they can just bet and make a lot of profit, or they are conniving with players for a share fo profit from subscriptions.
This is a scheme people should be aware of because, out of our eagerness to make money, we fall for schemes whose only intention is to scam us.
And if it's coming from Telegram, you have to be extra careful, there are so many scams on Telegram that our government is thinking of banning this application to stop these scammers.
