So, someone just spend over 220 Bitcoins or $11 117 000 to get $200 000 worth Lambo. Wow. I hope he didn't really purchased all these tickets and got it through wagering. If not, probably it will be most expensive Lambo ever.
But even if he wagered a lot of BTC and got Golden tickets in this way, it's still insane money. If he can afford to gamble so much, probably these $200 000 doesn't means much for him.
Some people just have a huge budget and get fun from gambling, so, they don't care much about the amount of money they spend. Some people have bought bitcoins back when price was very, very low and they have so much bitcoins, don't care too much how they spend some of them. Finally, this is crypto gambling, so, everything happens there haha.
the recent promotional deposit bonus was a bit unfair don't you think?
it said deposit any amount and get 10 new rolls on wheel of fortune. which means if you deposit 1 bitcoin you would get the same number as someone else who deposited the minimum amount of bitcoin!
i think such promotions should be based on amount deposited and you should get 1 new roll for every for example 0.005BTC.
The last time we did a deposit bonus giveaway it was for Golden Tickets and in exactly the format you suggested and ran for 48hrs each time. Unfortunately, one individual started depositing and withdrawing the same 2 BTC constantly for 48hrs every time we ran it. We think this is a lot fairer on everyone and a lot less attractive for high rollers to abuse.
Edit: I forgot the happy ending. They spent a fortune in mining fees and didn't win the Lambo.
I guess you have seen poker promotions where you get deposit bonus only on pokers. There, users can only deposit once and claim the reward according to the amount they deposit. The only way to abuse this is to register alt accounts. This will always be the problem and you have to carefully handle that. In case of getting lottery tickets via alt accounts, you could reveal them and burn those tickets. Current structure doesn't really look attractive, almost it looks like it doesn't even exist.
