   I understand it is their game not ours  they have the big guns and sit at the table we  look for crumbs to fall off it.

I can only guess what to do.   I can see right now they are super solid like a mighty king so to speak.
Some kings were smart some were morons. They did suppress the diff during the s-5 run they did not during the s-7 run.
  The s-5 held price a long time.  The s-7 did not.  So for me to be sure that I am right would be dumb on my part.
I do have something going for me this go round lower power  cost risk  with the solar array deal and a back up position with the small Eth coin farm.

But you could turn out more correct then me.  Time will tell

Nice numbers but do you really have that much faith in bitmain to keep the price high? all they care about is thier own profit , once the purchase rate drops to a number they are not happy with they will drop the price 30% like they did with the s7 and later on down to 50% , if anything the smart thing to do is sell yours now and keep your mined coins and then buy back when the price drops in a few weeks.

Thats what I'm waiting on.

My S7's barely made a profit for me with free electricity (the profit is actually in the resale, the BTC mined almost exactly matches the BTC spent for them).  S9's currently:
B3
paid inc shipping: 2.957
Earned so far: 0.671475368
Left to ROI: 2.285524632

B4
paid inc shipping: 3.149
Earned so far: 0.366534368
Left to ROI: 2.782465632

I am happy to see the price not drop too fast on these.  I was kind of pissed when the S7's were available new for less than I still need to earn to ROI on the early batches.  That's part of the reason I only bought two of these so far, I was hedging my bet a little.

I do mine with S7 and will continue to do so until it becomes unfeasible.
regarding strategies-here is one:
1. when bitcoin price is rising in $$, buy BTC.
2. liquidate btc for $ or buy miners at btc peak  .
3. mine into btc $$ price decline or stable btc/$ price, collect btc, pay bills with $$.

rinse and repeat-profit as long as long term btc price is rising.
right now, btc price is rising, so buy and hold might be better than spending.

It's all about timing. If Bitmain - like Phil was suggesting above - can hold the whole network stagnant for a few months then actual mining ROI might be possible for the early batches, depending on which wave of the BTC pump they were bought on. But if they drop the price 2-3 weeks from now then it's going to suck for everyone, including early adopters.

This sort of gambling is why I'm sitting this one out, hoarding my precious. Won with S5, lost with S7, not gonna martingale it.

Why would the price have to be corrected for the halving? It wasn't a secret.

You should not buy gear or sell coins   you need to wait.

My bet is they want to freeze difficulty as much as they can  which is why I grabbed five machines before the ½ ing.

Paid one off completely.  So this high price for gear and slow sale move on their part  was exactly what I was hoping for.

This happened with the s-5  diff went flat for close to a year.  

This is the only way I could  justify getting five s-9's before the ½ ing.

btw: how about makeing a software for these? 

LOL!


That's a very tempting idea. Sell now before Bitmain drops prices, resulting in everyone and their brother buying S9's which in turn will drive the difficulty through the roof. Then consider re-buying on the other side when things are stabilized.

Yes you are correct, they do not care about our profits, only our purchases from them.  This is a business.  I am holding strong right now without anymore new purchases for 2 more weeks.

They are perfectly priced from the viewpoint of bitmaintech  and all of us that purchased Batch 1 ,2 ,3.

I could sit and do a lot of fancy economic bs ...here is the bottom line  only bitmaintech can make a .1 watt miner in

bulk and  cheaply.

Since they self mine  they can sell their gear  at 1800 or 2000 a piece and only sell a few dozen a day.

All the while they retool hashnest  with new s-9's  and don't feed the hashrate much.

They have absolutely done a great job  for their bottom line.
They will not have to lower prices on the gear until:

 A) a btc crash
 B) a new build comes out with a .1 watt machine

I agree partially, some are idiots but I believe many are just hobbyist who don't care about spending money on their hobby, and/or are hoping the BTC price goes up substantially in the future. Nevertheless, they are driving the high demand/cost of S9s.

I've been mining since the CPU days and over the years have accumulated hundreds of coins at an average cost of $60 each and have already sold enough of them to recover all costs. But, I actually made more money from trading BTC. In any case I'm in a good position because I'm now playing with "the houses money".

I'm an electrical engineer and have always been into electronics and computers and such. The mining was a fun hobby and increasing the efficiency of my S1s, S3s, and S7s, like I know you have done, kept things profitable for a long time. I have a nice setup in my garage that can power four remaining S7s, which could be used to power four S9s, and would like to do so if it made any sense. I could try to justify by saying to myself "3 BTC only cost me $180 so the S9s are worth it", but that would be relying on false logic. When I do the math it doesn't currently make sense at my electric cost of $0.13/kWh to continue mining. You have to know when to hold them, and know when to fold them.

these new batches released after halving are still insanely priced way too high

So, I take it the price of S9 hasnt been corrected for halving yet? ... looks outrageously overpriced...

They don't give a hoot about your personal profit. In fact they f-ed all B1 buyers of S7 by constantly reducing the price.
I don't profess to know their motives. All i know is buying 2150/450 4.77 BTC at the time of purchase beats your "investment" so far with NO electricity used.
13/4.73 x440=$1200, pretty much fair price for S9 since S7 is actually worth no more than $350. 13/4.73X350=961, so i am actually adding about $250 for efficiency and S9 being "new". Unless they price the miner at $1000-1200, i am not buying for now.

They look to be on pace with the Batch 1 release if you price in BTC.  B1 was ~4 BTC and should have produced ~1 BTC by the time these are in hand.

I guess a few of the earlier adopters would have a bit more hash depending on how close they can get to the advertised 14 TH/s.

Because high prices like these make my batch 1 value stable.  I can list and sell them for 1900 right now as I type.

My hope is since bitmaintech is  monopoly wise  king that they stall sales via high price.  They have zero need to rush as of today.   Soooo  the wise guys that purchased batches 1 and 2  will be the winners.

Bitmaintech can make growth in difficulty fully stall..  They did it before:

Start at sept 25 2014 to Sep 16th 2015

about 360 days 


  we went from 34,661,425,924 to 56,957,648,455

if we do this growth from now until July 8 2017  I will do very well.

Since they are in control  it suits them to play this game exactly like that  as it will max their profit.

And it also maxes my profit since I purchased batch 1 and 2 before the ½ ing.

B8 and B9 are available for sale again...

B8 11.85 TH/s, 2.77 BTC or $1,828.17 USD
B9 12.93 TH/s, 3.05 BTC or $2,012 USD

I've been waiting to buy a handful of these but the price is insane, batch after batch bitmain keeps the price high and ROI is impossible.  IMO buying sometime in october these s9's will be barely cheap enough to get an tiny ROI.

has anyone else noticed the big farms in china are still on S7's ...they arent even going to S9 at these prices.. and id assume they would get an even cheaper price buying in the hundreds to thousands in quantity
