Congrats for all of the winners here, but as I can see here, the prize is a little bit small for the first place.
0.04
BTC is not a small prize. Idon't think there arer many casinos that offer higher prizes.
You can look that the amount of he got only 0.04 mean while he already wagered 7 btc which if it is 1% house edge then he already lost 0.07 btc but only recover small amount as well.
Wagering contest prizes are not supposed to cover your losses. It is a bonus, an act of gratitude from WB to their loyal users.
