I'm curious how much and how many hours are you spending on your gambling habit? Because I can't imagine myself losing right away just a few spin and of buy feature. Well, I'm a fan of the buy feature been lost a lot of money because of enjoying those spins it gives a different hype every time I heard the buy feature on the tombstone.
He spent from winning balance.
So, participated on 25$ contest and win both of the contest maybe multiplier & deposit race + the total win he gets from playing during the contest could be arround 500-1000$. I believe he was set up the lose maybe around 300-500$ and even he losing it all bitnity just losing 25$ from his own money.
But, let me guess for deposit race you need to deposit at least maybe 2-4 times because gambling with 25$ was pretty hard for the contest.
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
