I put money on Belgium (12.0 decimal odds) and Croatia (15.0) after the group stages, where some form was visible, combined with knowledge that they had some of the world's best players.

The odds shortened as the tournament progressed, I was able to hedge as the shortened odds made lay betting profitable.

(High variance in football outcomes means there's no guarantee of profit, I don't bet big sums.)

This answer is very useful and contains proper strategy advice :)

If someone were to bet during the round of 16, if someone were to bet $1 on the bottom 8 and $2 on the top 8, the strategy would most likely yield a small profit or a small loss, rather than a total loss.
