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?
Actually we never know how they strategy work on each player because I believe they sure have their own strategy to get profit or even to get this huge wager amount. And I believe for some big whale which make 14 btc wager sure is aiming for profit. But for the rest including me, may be we can count as small whale which is tend to lose this 1% from the wagering amount because from the start we are aiming for big wager amount
