Hi Folks...Has anyone figured out an easy way to keep the transaction fees and not pay 4% to antpool?
Easy, don't mine on antpoo. And as kano points out, txn fees are quite a bit above 4%, which is all the dwarfers made in "back to reality", but that's a different story.

I get the txn fees by mining on kanopool, have done since day one.

Ditto.
Why is it so many folks try to game the system be it as this case retaining Tx fees or (posted more than a few times) even attempting hacking the blockchain to 'earn' more? Way easier to just understand pro's and con's in mining and in this case -- looking at what other pools offer and picking one more suited to what ya want...
