I am sure many people could afford $30, that is not a lot of money even in the poorest nations to be fair, not small change neither, depending on where you live that could be as high as a weekly grocery store, or an electricity bill paid, but it is still not "a lot" in the sense that it is not rent money in almost any nation, maybe 1-3% of the world would have that as rent.
The another thing this is just one bet only, it's not like slots where we keep click the spin button over and over, of course if you bet $30 for one spin it's really a lot. But world cup is just happen every 4 years and the match will end at December 18, it's just $30 for a month or $1 per day.
Yes. It is a risky business to bet on the winner of competitions like the World Cup. After all, anything can happen in a knockout tournament. But with great risk comes great reward. A $5 free bet is just a bonus- basically, if your chosen team reaches the final, you have a good chance to receive your initial deposit in the form of a free bonus.
Yeah it's need 6 win streak in order to receive the initial deposit, it's already good even though the country we're bet lose in the final. But if the country become a champion, we will get both the winnings amount and $35 of free bet.
