If all of his bets we're at least $100 it's sill easy for him to take the top 1 spot as long as he have enough bankroll and with autobet it would probably take several minutes since the bet speed is 1 per second. I wouldn't say wagering 14 bitcoins is a lot unless he went big and sniped yoloer on the last few minutes of the contest. There's a few ways to do it without spending more than the guaranteed prizes but with the screenshot it seems he wagered more than 10+btc in less than 4 hours which is quite fast..
I really don't get it. Windice has an house edge of 1%. If someone wagers 14 BTC to win 0.1 BTC (price for the first place) he statistically has lost 0.14 BTC during the contest. So wagering that many BTC has no sense in my opinion except "look guys how big my pockets are" ... or do I miss something?
Sure it does not make senses if you uses statictic to compare how much is wagered by a player to how much he won from the contest. We cant generate that all users are losing 1% of their wagered amount as it is gambling where anything may happen. A users can win and lose any amount during wagering so the one who knows whether it is worth or not to wager that much for 0.1btc prize is the player only. If we use statistic then the 2nd winner gets even worst position because he wagered 12btc and won 0.05btc on the contest while statistically he lose 0.12btc for 0.05btc.
All in all, it is statictic only but we do not know the fact except the players and the site.
