In the previous golden ticket contest, I see that the user who won held 882,251 tickets.
If my maths don't lie, he had over 220 BTC worth tickets. Even at current value it's worth almost $8 million. This guy is huge whale and probably this $100k worth Lambo isn't that big win for him.
These numbers is insane, but at the same time it's pity that these whales don't leave chances for us, regular users to win something :/
Those amounts are crazy, wagering 220 BTC in a lottery is just insane, unfortunately it could be some dirty money coming from random scammers or hackers who can't cash out their bitcoins on the exchanges and who then try to convert them in another way. Well at least those whales give money to freebitcoin which in turn make us benefit from it by offering big prizes, bonuses and interests to everybody.
that would be the total amount wagered though not the amount of their bet. they may not even have 220 bitcoin in total in their wallet but they have made that much bet. and the Lambo Lottery runs for a long time so they had enough to reach that much by betting smaller amounts.
you can always see high rollers like this on dice sites if you visit those sites that list their top players.
