How many matches as a minimum do you pick on a particular sport betting slip?

[swift]

I actually pick about five atleast on a sport betting slip ,I actually don't putting too much and others ,so I just pick the little one that could enter ,even if picking more would increase my possiblity of earning more ,I actually know the risk attached and I am actually not ready for that ,that's why I just actually pick a minimum and not pick more not to regret .
