Am I getting cold cards or just playing bad?

[Me and You]

Hi all

I've played just under 10K $1-$2 on pokerroom and have a BB/100 of -.8. I have since moved down limits. To work on my game. However I have discoevered the crypto bonuses thanks to this site and have started to clear the 300 hand ones. In order to make money from clearing these bonuses you need to be better than -8.333 bb/100. Now considering my past record I thought Piece of cake. Well this is my second month of doing it and currently after 800 or so hands I am sitting at -8.92 bb/100 so clearing these bonuses is costing me money. Should I just give up as these tables are obviously beyond my skill or continue to persevere?
