Pretty bad advice seeing as how those "present" math numbers never materialize. This new FUD garbage is the newest catch phrase and is already overused to the point of nausea. There's FUD and then there's facts. Here's the facts. You pay $2700.00 for a unit with "TODAY'S" profit of $1,500.00 per month. But....you don't get it until several 100's if not 1000's of PH/s slam the network. Now you are grossing $400.00 per month on a $2,700.00 unit along with all the other blind lemmings. That's not FUD....it's just stupid. I already know what the worst case is on the S-9 and I can buy those for $1100.00. 2.50 S9's for the cost of 1 D3. 2.5 X $369.00 pm or, $922.00 per month. You do the math. I already did. More people need to. This shit is off the chain stupid.
