ZEC is crazy profitable right now but if you're a seasoned miner you know that you can't build on it for a long time, not even for 3 months.
But then again the 10800 Mhs X11 miner is even better, in fact it's a ridiculously profitable miner with a whole lot of smoke and mirrors surrounding it.
In fact, it's so profitable that currently it would only take 20 days to reach ROI, using the average, $6200 price. As I said before, let's just think for a second and ask who would sell such a crazy profitable miner instead of using them?
The answer is no sane person.
No self respecting miner I have spoken to even remotely considering buying one. A couple of promises and videos are not proof in this day and age and then there are the other red flags...
