Ok I have a suggestion to make, why don't you add an option on the betting page which would ask the users if they'd like to pay the miner's fee from their winnings, because this Tx: https://blockchain.info/tx/4cdbbee1f8491bb7b80bd996edbff7526bd29a0fad970d40e6d790b3a1aa2e34 has been stuck for 2 hours now and it's really annoying and if it had only like 5k sats more miner's fee it would have gotten confirmed by now.
