Dunno where the hell your buying from.. but my last batch I paid $1415 for each, and the batch before that I gave $1310 each. This is straight from Bitmain. So now, do your math again and tell me the ROI.

Good luck getting any S9s for anywhere close to that price.
They were around 2k during summer this year and now $3500 is still on the cheap side. Furthermore, whenever you bought your $1400 S9 units, the Bitcoin price was a lot lower which would've dumped the ROI way back down.
All you do is cherry picking, because you're clearly heavily biased towards mining, perhaps so you won't have to admit that Bitcoin mining isn't really worth the trouble. Are you perhaps trying to dump your Antminers? Or are you just trying to save face?
Whatever the case may be, your complete inability of objectively analyzing all relevant points simultaneously invalidates your opinion, which is not even close to being an assessment.
Wow. Simply Wow. I mean literally WOW. (smacks forehead)
Those prices were the last active prices I ordered at. Simply load the page man, $1415 was the last batch they sold. I promise you any miner here can verify this and verify the prices I quoted.
FACT: The sons a bitchs make money, and those of us who bought s7's (which still make money) and early S9's from batch 1 up are banking on them. Idid your friggin math, and even if BTC were only $5k USD they still turn ROI in 3 months. Please quit preaching your anti-miner semantics as they simply do not add up. Any person with 4th grade math can figure that out.
You call me a cherry picker because I am biased on mining. Know what... Your right... I am. Reason being it makes me fucking money, pays my bills, allows my farm to continually grow and diversify.
I seriously don't get you on the whole sell/dump my Ant's. Do you see any threads of me offering a miner at all? Didn't think so. Sure, everything is for sell at the right price. But no way in hell I would sell at what I can buy them for due to time in getting more. I would lose more than I could possibly try to gain.
Save face? Heh? I stand where I always have. Seems to me your the one who is offended/jealous that you realize your own philosophy on mining is totally construed and lacks any merit whatsoever.
Ability to analyze all relevant points..... Hmmmmm... Your the one that cannot simply do math keyboard warrior.
Sorry, I should just stop feeding the fucking trolls and stay on topic as it is clear this forum has a ton of them.
Back to the question asked. With 1 Bitcoin at todays rate with no farm on hand I would buy 5 s9's and run their tits off and bank next year. If I had 10 bitcoin I would do the same, but only with 7. The rest I would load on multi usb's and put in the safe deposit box (hint hint).

And by the way, it takes forever to even get an Ant from the main page, which also costs over 2k with a PSU. Hence the high prices from just about any directly available source.
And no, I'm not realizing anything you're suggesting at all. Maybe if you could provide real net profits that consider price changes and network difficulty we can talk. But I've already done the Math with generous and harsh estimates and it's simply not worth it if you're out for maximizing returns. If that is not your goal, then that's perfectly fine, but you keep insisting on the contrary.
