I would add ETH. I do not personally have any LTC at the moment, but it also a good option. There is also a new coin/token being engineered just for online gambling, but it is mostly geared towards traditional online casinos and poker rooms, not so much the bitcoin only variety.

Too bad. I was interested to check it out to see how it compared to traditional online casino models.

Is your payment processing restricted entirely to bitcoin, or do you offer other methods as well?
