Yep, the user has won the Lamborghini from the 10th round. He is indeed a whale at Freebitco. The same user had
32k+ tickets during the 8th round of Lambo draw. He was the 4th highest ticket holders in that round, but not lucky enough to win the Lamborghini. Hopefully, the user hasn't lost his reward during this big wagering journey.
If we keep in mind how much BTC this user has wagered recently, I doubt that he hasn't lost his Lambo lottery winnings yet. However, if this user has previously collected a lot of golden tickets in previous rounds of the Lambo lottery, it can be assumed that winning the Lambo lottery and then losing 3 BTC isn't significant for him.
He is likely an early adopter and a whale, so he doesn't care how much he wins or loses. I have seen an early adopter playing live with Bitcoins like it was nothing, just a number. Freebitco offers 4% APY on deposited Bitcoins. If we keep in mind his past activities, he might have deposited 100 Bitcoins or something like that and probably receives 0.01095890 BTC reward daily, doesn't withdraw them and just gambles or buys tickets for fun. Probably that's why he claimed his reward very late in time. User 37419370, the current Lambo winner wagered 199 BTC in the ongoing contest. He wagered 29 BTC in today's daily jackpot contest too. Hands down, THE WHALE.
- At the wagering's level that you have described, House Edge can be provably close to zero:
House Edge -5%
5xRP +1%
Usual Bonus +1%
Special Bonus +2%
Prizes D+W+S +1% +5%
---------------------------
Sum 0%
So, that sort of user is investing in the house's side rather than in the gambler's side.
