Hello all, I just found zero on WTM and was looking into mining it, but I'm concerned with the mining fees.  As far as I can tell, there is a purpose made Optiminer that is the only way to mine this coin and has a built in 2.5% devfee in the newest version that's available for download.  Is this the only way to mine this coin?  Can the fee be edited like in other equihash miners?
