So I will ask my question again here:

I'm  planning to deposit ETH to FJ and play roulette. I noticed in roulette games they have chips of 0.25 to 100. How exactly my eth will be exchanged for the chips there, and my winnings will be credited in eth as well? Also eth price changes all the time, will it influence my balance at FJ? I tried to to talk to live support, but unfortunately those girls making me more confused with their messy and partial answers.
