If I look at your wagered amount of 186 BTC and 689 ETH u should have lost in theory 0,93 BTC and 3,44 ETH. But u want back 30k USD?
In theory I should have lost nothing, because 0,5% house edge minus 0,5% rewards =
zero.
seems like the amount you lost matches the house edge?
If you know the exchange rates when I lost the 186 BTC and 689 ETH, then you can calculate how much 0,5% is.
