I cannot believe that people are ordering these.  You will be mining after the halving with these and a best case scenario is that you break even in about 2 years.

What are you guys thinking   Huh Huh

Nice machine. Bad price. No surprises.

The Bitcoinwisdom mining calculator does not automatically take the halving into account does it? I don't think it does, which makes it a little tricky to really compute an ROI. You basically have to come up with a value up till July 10th, then compute again from that date with half the hash rate.

When I do that, it doesn't look pretty. At 5% difficulty and free power, one of these rolls in with a 430 day ROI. Of course that's probably optimistic because when these hit the streets the difficulty is going to go through the roof.

So I tried modeling a 10% difficulty up until the halving, and 3% after (assuming that things settle down for a while). That turns the ROI into 304 days. This is still a very risky investment.

Basically this is looking like the S7 all over again. I never made back the BTC I put into those B1 units. I only got ROI in fiat terms because BTC doubled in price and I sold off my miners early. I would have been much better off just buying BTC.

I'm going to sit this one out and see what the landscape looks like after the price drops.

Please everyone buy as many of those as you can so that Bitmain can ROI faster and lower the price for Batch 3 or 4. Thank you Smiley

Seriously though, a great machine (I didn't expect 0.1 GH/J) but the price is a big FU.

Exactly this.

More Guineapigs/Lemmings required to purchase these please - roll up, roll up!

I'll come back in a month or two when faults/prices/shipping delays are within reason.

Do not trust Yobit scam exchange or shady ICO's run by known scam companies like HashCoins - they WILL steal from you:

Ditto here except I have 3 different batches of S7's that haven't made the cost back (in BTC).  Should have just held the BTC.  I expect the value of BTC to rise more in the coming month so it looks even more likely that holding BTC now is going to offer a better return than buying one of these.

I'm a fan of self control, but only in moderation.

The positive is the miner design is already proven and it is unlikely there will be a significantly more efficient miner any time soon. (10nm mass production capability is at least 1 year away; plus moore's law is over)

The negative is this is more or less a confirmation the network is about to hit 1.7 Exahash.

Bitmain please release a 1 blade version: should use ~500 watts for 4.65 TH/s. This would be much better for the home miner and would further distribute the network.  The S9 + 2nd block reward halving will paperweight anything older than an S7. 

I could convince a lot of people to run a 500 watt miner; a 1375 watt miner is almost universally a NOGO.

Here goes nothing...
(Remembering Batch 1 of the S7 eh Phil?)
It's just money, right?

well they did finally pay me the compensation.  Roll Eyes


Which is why I got this one. 

So effectively  I was paid 150 in btc on may 1 which turned into 200 now.

I sincerely thought they would not ever send the money to me.

So I am paying 200 less then normal on this. Grin

The solar array will move from  22th to 36th.

Maybe I will sell a pair of avalons to off set the cost of this a bit.

 nominal power consumption of 1375 watts*.

TL;DR Fuck home miners.

I guess Ethereum is where I focus now.

Impressive... probably will wait until at least batch 2 or 3 to see where the price falls. I got sucked into Batch 1 S7 and that price changed quickly...

same here. will wait too.

Yea with the halvening happening a month from now, these are too highly priced to be taken seriously.  I'll just hobble along with my 2.3 S7's and shake my head at the people plunking down thousands for this new hardware.

This FTW !!!


It's a shame you have to secure another chain to earn btc, some people might stay on that chain and leave btc for good, but that's what you get with centralisation of the (hashing) power

Why would they want to force people to buy their PSU? I could care less for it.
I maintain that they would have sold more if they focused on typical US residential limits.

As far as profitability is concerned, others already posted.
Basically, most calculators don't adjust for halving.
What i did was to input original numbers into vnbitcoin, then get revenue until July 15 (I know that it would be 10, but calculator did not had that range).
That revenue until July 15 is $673 with 8.9c power.
Subtracting $673 from $2100 yields $1427; add $50 shipping=$1477
Then redo calculation and in order to simulate halving, just input 7th instead of 14th, 1400W (at the wall)
What you will get is infinity with $400 deficit in June 2017.
You could be bailed out by btc price, but btc just spiked, so how much more up can it go (short term)?
I would not even buy coin here.

Perhaps they will make an S9-N .. *shrugs*.  IMO after 800Watts it's to much draw on one home circuit..

I would prefer 200w though.

rebate is separate money from a new purchase in my book.
see my post re profitability of this machine.
It could be very profitable in $$ if bitcoin goes to 1100, but then I can just buy btc (which I am not doing either).
One positive-since they are trying to support the price by still selling S7, then S7 could still be $400 by halving (good for resell).

Looks like good bye to my avalon but the problem is antminer s9 is pretty high price and many people are saying that its not worth it to buy its not profitable.. difficulty still the same as before ..

I think I - like many others - am going to wait until the halving to decide whether to invest or not. By then we'll know what has come from the halving, what it does to the price and what it does to the difficulty. The price might also have dropped on the S9 by then. Besides all that though, I don't have the funds at the moment Cheesy

I would have been much better off just buying BTC.

Has this mantra really changed since the S7's though ? I thought the S5's were the last (barely) profitable offerings for home miners.
