Whenever you see or hear people claiming that they have a strategy that can guarantee you 100% for something that has to do with chance just know that there a 99.9% possibility that such person wants to scam you.
My question for you my friends is are there sport betting groups that gives betting calls that are legit? Because I believe that if anyone knows a way to change their life around, they won't tell anyone, they will enjoy the moments and pray it last forever.
There don't have anything to offer all they are seeking for is someone who would be gullible enough to believe them.
I have seen them before on twitter, facebook, telegram and even on some whatsapp TV status they always come with some proof of them winning and never lost a single bet, and tell you all kinds of sweet stuffs like they will reduce your registration fee blah blah blah. I have never join and never will, I just look at all of them as scammers and up till this day I haven't seen anyone that has joiend their channel that came to testify about their winnings.
