Good Day,
Who are you referring to as OP?
He refers to babananak, I guess!
What will happen if the 12billionth bet isn't a bitcoin roll?
Will the prize be in btc still?
If you hit 12 billion bets with altcoins that means you will get the minimum prize, it is 0.01 BTC! And for the lucky rolls, you have to play with bitcoin ( min 0.00001 BTC ), otherwise your entry won't be count.
