Perhaps an option to allow for more delayed payouts in BTC would allow for better returns.
I don't think it works quite like you're thinking...
Here is the payout transaction - https://btc.blockr.io/tx/info/ac4c97f0965ac1d3228d8c0b0a3508cca6b69fccc6aae88c406823e4f99e1a6b
BTC paid out - 4.02472877
Fee paid is - 0.01963269
So that fee is ~$53 and I assume it is spread across all miners that you can see that got paid.
Although it would be great if Crackfoo could confirm
I pay the tx's fee's, they're not spread across miners balances.
