Here are a few of the DevFee addresses found within v11:
0xB9cF2dA90Bdff1BC014720Cc84F5Ab99d7974EbA

Now that you've explored the blockchain with these, here's how you can bypass the DevFee without incurring a penalty or installing some malware if you don't think Claymore deserves this fee. It isn't for noobs, so don't ask me details if you don't understand. Pay the man and learn.

How can you a do so absurd proposal ? if claymore was not here we could not dual mining, i'm happy to pay them
