Yes, the word 'roulette' for an algorithm is good, but it is not a good trademark for a coin. I almost skipped reading the thread because of it, since in the shadow of CasinoCoin JackpotCoin BetCoin or whatever, how interesting can it be with a RouletteCoin? At first, it sounds like a novelty idea, a cheap clone. It is misleading as it does not indicate innovation and thought, nor integrity or character, just a rather blunt gamecoin. It would be a pity if this coin went by unnoticed.
Please re-consider the brand of the coin. Keep in mind the competition for new coins are fiercer than ever, most investors and traders only take a few seconds to browse through a list of (to them) unknown coins. One needs to stick out in a credible way.
