I meannnn I don't think it'd hurt your bankroll that much? Since you're picking high-odds games anyway, just bet lower amounts if there are more games to play. If it's close to the final few games, then go up in the amount instead. Personally since you've experienced it yourself that it isn't working then maybe rather than blaming you for picking higher odds, blame instead how you're reading the matches. Like at this point I reckon you're just waiting for a team to get a high odd placement without bothering whether they can even give you your win (based on whatever condition you're betting on).

Still think you're good on going high odds instead though. A lot better imo than low odds since low bet and it's not even a real guarantee of them winning.
