^and^^, thank you!

about 7 days USA

It took 5 days to deliver batch 9 to my place (Finland). The carrier was Fedex.

How long shippment usually takes from Bitmain?

There's no other way for them to compensate those who bought S7s in the first batch. You can't even sell your hardware half of your purchasing price.

ok

The compensation for Batch 1 problems. They said they would properly compensate and they never did.

What is this?

More positive news to cheer everyone up since the overall mood is the SKy is falling for this entire month.

Bitcoin price has surpassed the US$455 margin in major exchanges. The positive announcements from the Core team and the increasing demand from Chinese investors have contributed to the rising price of Bitcoin.
It spiked up to $455 today.  WOWzzzzzzz

There is no problem with the fans, the Controller board has it's own PCI-e power connector & separate interface components for each fan. Early S7 Controller Boards were tested with 9 hash boards however later ones had a change to the firmware which reduced the max number that could be supported.

Surely someone have tried connecting more than 3 Hashboard to 1 S7 already right?  Makes me curious if the current controller is even capable of handling up to 6 high wattage fans like the ones used on the S7 as that's 6 x 35W = 210Watts which is a lot.  On the positive side, the network difficulty seems to be increased less than expected based on current prediction from bitcoinwisdom.com.  Hope it will stay that way for a while.  Time to make some BTC quick.  =)

I suspect it's nothing more than a cost reduction. They can soon change to assembling boards with the full compliment of connectors if they want to do an S7+


Rich

It could be luck and they used up ones they had left with 9 connections.   I wonder internally if they use 9, it would make sense that internally they like 3 together.  That is pure speculation though.   

I am surprised they stripped them I always thought they might have did it for a S7+ one day, just like they did on S5+.   But then the latest ones don't have 9.  So I'm not sure what to think.  Makes me think no S7+ in near future though or they would focus on 9 board versions.   

David,

To answer you question.  All 3 of my Batch 10 units and 7 of my partner's do not have the 6 FAN or 9 Hashboard connections.  They strip them off just like previous batch, although some units did include it in the past

As I said, don't buy it if your plan is to just break even.  Not buying one will achieved the same result.  

Buy it if :

1) You want virgin coins as some people may not want any tracking via Coinbase from purchasing / trading BTC.  
2) Operating a mining business as there's many tax benefits
3) You have free or super cheap Electricity rates.  I'm at 6cents / kw and am still trying to get to 4.5cents.
4) You're betting BTC will go above $500.  If it does, I don't think these S7 will be worth nothing after the halving as you say.  People with free or cheap Electricity will still be buying it from you.  Heck even people who wants Virgin coins are always  willing to mine at up to a certain percentage loss.   Also by Sept, people may be buying it to get ready for the Winter heating.  These things are better than Space Heaters and can start a fire just like a Furnace as well.  =)  S3/S5 are proof that even though they can't cover their electricity cost,  there are still buyers (Want to learn, free Electricity, want it for heat).  So I don't think it won't be worth anything by July.  Heck, if we're lucky and BTC goes up quite high, it may be worth over $400 still.  I've tested selling many units lately with all the panic selling going on with Batch 10 being at $780, all mine sold for well above $800 still.  So the demand is still strong and many people may not want to wire or have BTC to buy from Bitmain.



It's all a gamble and it's definitely not worth it for the average home miners.  It's more for people who are willing to gamble and match most of the above.  For everyone else, it's just a soothing feeling that you're able to recover more of your investment then previously thought when it was at $380 and felt like it's going to crash below $350.  I'm very heavily invested in the S7 due to my partner's decisions, but I never like the product nor their business model.  How can you win when the company selling the products to you is also competing against you?  This is why it's hard to get their product at a price that make sense, unless you have other cost advantages via a business to offset this.  So unfortunately this is why it's very difficult for home miners to make money unless the 9 planets line up perfectly.  



  

i dunno, i want one too. but.. i still think 720$ is too much..

all my calculations. even if you throw out the cost of electricity you wont get a return until july, which is when the block is going to half making these absolutely useless.

even with 5c electricity you cant break even..

if the cost was 400 or even 450 i would have gotten one..

If coins went to 525 over night and bitmaintech keeps price at 720 .  As angry as I am at them over batch one.
I would consider getting another s-7 for the solar array.

If the fuckers would have paid me for the low hashing s-7 I would not be writing this but I actually am thinking about getting one Sunday morning.

$500 price is definitely not far off considering we're at $440 now and were at $465 last month before Michael Hearn rocked the boat badly.  I would consider $500 the minimum BTC price after the halving to make sense to continue mining unless we get much cheaper miners per J/GH to compensate for the lower pay after the Halving.  This is taking the PUMP and DUMP to be expected with traders buying a ton before and selling it after the halving.   I did some selling just to see how the market is and not surprisingly the demand is still very strong.  I was able to sell 10 x S7 and 4 S3 and 1 Avalon 6 all in the same week.  This is on top of over $3000 worth of cabling, PDU and PSUs.   I would not consider buying Batch 11 or any other miners right now with the hope that you can break even as you would break even simply by not buying one to begin with.  This is a game of cost and the winner will be the one that can operate at the lowest cost or operate it as business where you can write off many things.  The rest is entirely up to Luck (Miner choice, pool luck, BTC prices, etc)

P.S Home Miners can turn their garage into a mining business and leverage all the benefits, so if you do it wisely, home mining is definitely not dead.  Just don't expect to win if you have high electricity prices.

The real winners though will be the ones that bought in around 380.  If it does go up to around 500 (which I think is a way's off).  But if it did they made 180 dollars profit per coin.   So I think there is something to be said for buying some coins at times.   

I will say selling my old generation gear when I did and buying coins with it.. looks like it will pay off.  I will eventually buy miners again with it but as of right now I'm enjoying having coin in hand.

Batch 11 is looking pretty cheap considering past prices at 720.    But you also have to keep in mind we almost haved since Jan 13 on difficulty if you add it up it's pretty shocking:

Feb 19 2016   163,491,654,909   13.44%   1,170,318,852 GH/s
Feb 07 2016   144,116,447,847   20.06%   1,031,625,717 GH/s
Jan 26 2016   120,033,340,651   5.89%   859,232,121 GH/s
Jan 13 2016   113,354,299,801   9.12%   811,421,684 GH/s
total      48.51%   

I agree, you should only support vendors that do you right.  There will be more options coming soon (April/May), so you will have more choices.  But with BTC going up, there's finally hope for the home miners and others who have invested heavily into the S7s or Avalon 6.    Your Solar farm is definitely another amazing angle I would like to see.  I've subscribed to that thread.  Really wish TX would offer better incentive for Solar as I also invest heavily into CSIQ solar stocks but we're OIL country here.  Let's hope BTC go pass $500 and remains above that so we can continue mining for longer period of time.
