The problem is all of the miners are somewhere else.
Ah, too bad.
It was a good idea, but miners do not care about donations for development and exchange listings this way.
Till next one...
I think the problem is that a lot of people, myself included, don't understand what you/this was trying to do, nor what we had to do to achieve it.
If you can explain the goal, and then number exact steps required by us, I am sure you would get more traction.
Pcminer runs a pool for mining BTCZ.
He created a special fee on his pool. 0.5% of mined blocks. That 0.5% is sent to BTCZ donation address for marketing and exchange listing from the OP. Poloniex and Bittrex were mentioned but it turns out they do not have to be paid. Others like cryptopia and ccex require 4 or 5 BTC.
It was a good idea but miners are pointing hash to other pools. Maybe they are donating by themself or not. For me it was easier this development fee way.
