I think that it is not about the excitement of the gambler, but about the wealth of the gambler, as the commission in the Bitcoin network is much higher than in other networks. I try not to gamble using Bitcoin, because I do not see the point of overpaying for the commission. In my opinion, it is much easier to exchange Bitcoin for one of the alternative cryptocurrencies or steiblcoins that accepts gambling site and deposit the funds received. After winning a big win you can withdraw them and buy Bitcoin to multiply your funds in the long run.
