I never had luck with those "Billionth bet" promos. Basically during that time, people make so many accounts and create so many autobets that its ver y difficult to predict when the Billionth bet will happen.
It happens pretty much on any casino that has these promos, during that minute or two. Crazy amounts of bots are hammering the site to win the promo.
THen they all logoff if they didn't win. Not really fair for the regular traders.
No man, you aren't right because bitsler has it's rules on 10th billion bet. I mean that you need minimum 5 level to be able to take part in promotion so it's nearly impossible to wage more than 1 btc because it's very risky.
Also another surprise sounds very good, I hoped that it would happen, Baryom wouldn't forget great and unique promotions, hope details will be available soon.
