You dont need send me money in advance. Send me 3 time your win match, can I trust you have really good matches. You can bet 3k on Czech Republic football 3rd league?? Very hard, but I can. And somebody who need help, I can help.
If you are that much precise with your betting picks, why don't you bet yourself and make a lot of money? Secondly, you may provide three betting predictions correct based on luck only and then you try to scam those people who trusted you by seeing your three correct bets.
However, if you are not so lucky with your initial three bets, you will try with another customer and you have nothing to lose.
