+Klađenje je jedna od popularnijih aktivnosti među ljudima, a kada razgovaramo o razlozima zašto se netko kladi, uglavnom ćemo doći do zaključka da postoje dva glava – zabava i želja za zaradom. Oni su sasvim logični jer kladionica zbog njih i postoji, no definitivno imamo još nekolicinu razloga zbog kojih se igrači bez pravilno odrađene sportske analize odlučuju postaviti neku okladu.
