Usually contests in Duelbits players try to secure a position in the multiplier contest If get a safe position then hunt for the deposit race, this is my way.
Yes for the contest Deposit race is not enough to make a deposit 1-2 times I even made a deposit 7 times before reaching the target
If you have more money, you can play both at the same time ~XD.
If not wrong Hhampuzz + Duelbits allowed you created another account to participated in the deposit race, as long for only contest purposes, not abuse purposes. 7 times was quite big, the total you spend could be almost the first place reward deposit race.
Not tired to give some advice, always control yourself for gambling okay don't too addicted ~XD.
