The result will be the same if you bet on a small amount with many matches and a big amount with few matches depending on teams that you will bet on. I suggest that you bet a huge amount on teams that you think has a huge winning ratio, and make variety of bets.
I think when you bet a very large amount you will experience a very large loss when you lose because no one can guarantee that your bet can win, it's better to keep betting a little by minimizing the risk of potential loss, at least by way of it can manage gambling capital properly and is not greedy.
