it is worth of it, to mine zdash?
I would say so, yes. We're on a very small exchange at the moment and with the current diff and price I get around $2-2.5/day with one 280x at 170h/s (gpu alloc 80, -i 1 and 1020/1650). Let's say I get 20 Zdash/day. That's 0.00270000 BTC/day, I actually get 25-30 it seems but I'm not sure. Then add the fact that when we hit a bigger exchange and everything is ready, the price will go up. Hopefully we wont see a way too high hype but instead slow and steady increase.
We have several things going on right now, we will inform you as soon it's ready.
