B1 S9 is gone again?

This thing is going to make the difficulty go to heights never before seen and massive 20% increases are pretty much guranteed. But WOW this thing is amazing its too bad the halving is happening so soon, itll be hard to be profitable but then again who knows what will happen after the halving anyway the btc price can spike up or old miners turn off lowering difficulty, only time will tell i suppose

Oh man the S9 that was pretty quick from the last release I feel like but I guess in the bitcoin world things move real fast lol

Shipping is right after the Dragon Boat festival. I hope that doesn't mean shipping delays for those that bought B1.
Probably not. You have to hope they learned their lesson from the S7 B1 delays.
Probably not. You have to hope they learned their lesson from the S7 B1 delays.
The lesson being "let's promise compensation and forget it until months later"?
Ah sweet monopoly...

you guys are wild, but I like the spirit of "shut up and take my money"
June 03, 2016, 07:52:30 PM
I may order a third one today.
June 03, 2016, 07:44:10 PM
Ditto. Was afraid I missed getting one as with Summer upon us I want to take 3 of the s7's at home offline and replace with the s9. 'Bout the same TH/s but knocking 2.6kw off of the heat load my AC has to handle. Happy Happy, Joy Joy!
June 03, 2016, 06:31:21 PM
I think we will see soon Bitmain S9-LN with PSU about 7 TH/s , 700 watt. Its gonna be more comfortable for home miners. IMHO.

No -- It really is a no-brainer vs keeping the S7's Running
My Calculations include shipping, customs and leave a little spare -- 3 Machines - $180 per month - Where do you find power costs like that? -- Each Machine uses around 1000Kwh per month $110 per month to run each -- that is a saving of $220 per month -- 2 months pretty much pays the difference no matter what happens to the price or difficulty
Return on investment on the S7's MEH -- Not really important for the decision to upgrade. ROI on the cost of the upgrade (in power savings) is in 2.5 months tops -- ROI on the total cost --- I don't really care
Well, I don't see how this is actually a no-brainer. You are exchanging 14TH/s for a more efficient 14TH/s, not actually increasing your hash rate. With the sale of your S7s covering 75% of the cost to upgrade you are still paying a minimum of $525 for that increased efficiency. That's if you had already taken into account the shipping and customs/VAT <- depending on location. If you simply mean 75% of $2,100 you are probably likely paying close to $600 for that increased efficiency.
The average cost to run 3 S7s for a month is $180 from what I've experienced and what I've seen other share. The S9 will potentially lower that bill to $60. That means you are saving $120/month with the S9 in place of the 3 S7. So that efficiency upgrade will, by itself, will take 5 months to ROI.
But that isn't the end of the story. Have you already hit ROI on your S7s? If not, you didn't pay one investment off before buying another. That means whatever you had left to ROI on the S7s must be accomplished by the S9. The S9 can concurrently contribute to both the efficiency upgrade and the initial investment which does help out. Depending on the batch of S7s you could have anywhere between 0-7 months of hashing remaining to ROI.
Best case scenario, you already hit ROI on a triple Batch 1 S7 setup and can focus the entire profit of the S9 into that $500-$600 investment for energy efficiency. In this case, you're right, no-brainer. That would be a quick 2 month ROI. Worst case scenario you still have 5-7 months to ROI on your current S7 setup. This would mean your shortest ROI period is 5 months, with the longest being approximately 6 months (5 months to ROI on the energy savings investment running concurrently with the 5 months to ROI on the initial investment. After 5 months, the energy savings can then be applied to the initial investment closing the gap from 2 remaining months to potentially a single month).
So without knowing exactly what batch S7 you have or the remaining months to ROI on that investment it is hard to say, but you could be facing anything from 2 months to 6 months to ROI. As you're selling your S7 now, that timer won't start until you receive the S9.
I don't see how anything about that was a no-brainer. I would have to give serious thought about taking on a 6 month ROI. That's quite a bit of risk considering all the variables and potential for failure and having every egg in a single S9 basket.

I'm in North Texas on a 100% wind plan that is $0.067/kWh. The guys on coal are getting a slightly better deal and farms are at half that cost using commercial accounts. If you're trying to mine at >$.1/kWh I could understand paying $500 for efficiency. Then again, if you're mining at those rates you're never going to get your BTC back anyway. Which explains your closing statement.
Most people care whether they make their money back so this isn't a no-brainer for most people.

*cough**cough* buy some bitcoin muddles under his breath *cough*cough* https://bitcoinwisdom.com/markets/coinbase/btcusd
edit. maybe just something around 10 20% of what you would have put on batch 1..This has some great upside potential yet. IMO 700 - 800. but take that with grain of salt:)

When the next batch of S9's become available and assuming that the price will still be 2100 USD (I am not intending on starting a debate on what the price will be), does Bitmain adjust the BTC amount to reflect the current exchange rate of BTC/USD?
Generally yes. BUT they only do it once per batch from what I've noticed (mind you I dont pay real close attention).
So they set the price when the batch is made available for purchase and the BTC cost stays the same (even if the BTC/USD price changes) until the next.
In the past there have been two ways Bitmain sets the price: USD (and BTC price floats according to the exchange rate) or BTC (and USD price floats).
S9 B1 price was set in USD and the BTC price was floating. The exchange rate is at the bottom of every page on the Bitmain website. It might be lagging from the usual Bitstamp/Coinbase/etc rates, often in Bitmain's favor
, but generally accurate.How they will set B2 price is anybody's guess.

anyone can calculate how long can take profit after halving 
Anyone can ESTIMATE it - but there are a lot of variables involved, and 2 of them (network hashrate which sets difficulty) and price are going to be guesstimates at BEST.
Very few folks anticipated the release of the S7 driving difficulty back into double-digit increases per adjustment for several MONTHS - which wiped out the price gains and then some over that same time frame, though the price gains were a lot faster which gave a short-lived "income increase" to those of us that were mining at the time.
There is always a RISK factor involved in mining - the risk that diff will go up more than price (or that price will DROP) and reduce profitability enough to make an investment into mining hardware lose money. That risk is helped a LOT if you have very low cost electric, as your profit is more resistant to diff increases and price drops, and it *ALMOST* disappears if your electric is free (you still have the risk of the hardware dying before it pays back for itself), but it's still there and you CAN'T "calculate" it, you can only ESTIMATE it.
