Thanks for your suggestion, we will consider offering such an option, or pay more fees for smaller payouts.
By the way, sending transactions with 0.0001 BTC fee no longer guarantees that it will confirm fast. You can still wait an hour or two during busy hours.
You maybe right but it does makes the transaction from 'Medium priority' to 'Higher priority' and it may get confirmed faster within the next block than 6 blocks and an added option which a player might/not choose would be really helpful. Thanks for considering it.
