With the race nearly done, there are indeed big bets being placed so to rank up in the standings.
While doing a few rounds on crash I had seen a platinum 6 player wagering 130eth per round while I was there.
The thing landed on under 1.20x all those rounds but the player raised his wager amount up to 300eth every round until I left
I have also seen the bets of that whale, he was betting 65 to 130 ETH in crash game, but he was losing most of his bets. He had reached to the diamond rank when I was watching his bets. I have wagered $332k in a month and got 2469th position in the race. The whale wagered more than my monthly wagered amount in just two minutes

.
Whales betting more than our entire savings is common, I have watched a guy wagering 12000 bitcoin in a single day once, and not like this was during when bitcoin was low neither, this was when bitcoin was at around 10k dollars, which means that 12000 bitcoin wagering was around 120 million dollars give or take, and he lost about 300 bitcoins total as well, so that was about 3 million dollars and he stopped.
This dude wagered my entire balance in a single bet, he wagered about 1 bitcoin per bet give or take ,some times even more, sometimes a little less, and I never had that much money before, and this guy was doing it per bet. It is cool to watch those things, I feel jealous a bit but also love watching them.
