My first day of mining when I received my Z9mini on 6th Sept was 0.08802152 ZEC
-snip-WAKE UP!! NO MORE PROFITABLE MINER NOW!!!

And you started on September 6...
The video was uploaded on the last week of August but it indicated "
ROI'd in 8 months", means that there were already thousands of Z9 ASICs mining Zencoins and others 8 months before that video.
bait.

Nope, it's "
clickbait".
Not to encourage Antminer Z9 sales, but for youtube views

The bad thing is, some users got the confidence to buy Z9s even if its too late because of this post,
and it's 90% their fault for not researching (
not VoskCoin's).
I always strive to illustrate this in videos now, especially when it comes to ASIC mining because the returns diminish so quickly
