suggestion what if somebody creates a btcz miner and like ewbf certain % goes to the developer , what if we make use of that fee to get us listed on those exchanges that requires payment.

That is briliant. Someone sent email to suprnova about a special fee for development and no response. Then pcmining.xyz introduced that fee but miners are just not joining. This could change things...

Seems like a good idea worth looking into.
