My recent betting report for the World Cup

So, we are moving on to the quarterfinals. The World Cup has been very unpredictable, and I don't think there are many bettors who are in huge profit, unless some lucky guy bet on Russia to advance, or Belgium to win without overtime (this one would have been great as a live bet). Anyway, I'm not probably betting on the winners anymore.
So, we had $40 starting money and we put two huge bets two days ago. They were header in Belgium v Japan and an acca on 7.5 corners in for games during the 2nd and the 3rd of May. Two headers happened in the BEL vs JAP match, so the @2.4 bet was successful enough.
However, the corners... All of them went through very easily. 16 corners in the aforementioned BEL v JAP, 14 in BR v MEX, 10 or something in SWE v SWI... AND SEVEN IN COL v ENG. Really?! It was a disaster.
All in all, here are the results so far.

Starting money: $40
Current balance: $33.86
Profit: -$6,14
ROI: -13,6% (if my math is correct)

If there was at least one more corner in the last game of the Stage of 16... Well, anyway. The World Cup is impossible to guess, I think, so the loss is not so huge. I will go through a lot of statistics and will bring you some amazing bets in the future! Probably not for the 1/4 tho as I will be on a holiday vacation.
Good luck and see you soon!
