Is this website still going? Seems to be. But, some comments have been ignored here. So, I am not sure if the website is still safe.
How many bets to date? How much total BTC on that number?
The site
http://blockchainroulette.com/ isn't working, and OP hasn't been around for more than 1 year. There is absolutely no reason to consider the site still working.
Thanks for the solid so fast, friend. ~darylluke.
