So this User ID 6922573 won around 3 bitcoins (Lambo) in the recent Round 5 results. Wow, that a big amount. Did the user take the Lambo or preferred to take the bitcoin instead ?
We see no one coming on this thread and telling that he won this Lambo.

It's up to them if they tell you or not. I think they will but not this forum. You'll find a lot more conversation in our other thread on the Gambling board.
The winner of the lambo was a bitcointalk user,
Kryptoverdienst. They weren't really active aside from a single post. He won with a somewhat small number of tickets.
