Bitcoin FTW!
Interesting move on the T9. I wonder if its appearance is related to the recent steep rise in difficulty.

They were due to either release more S9's or something like this. Doesn't matter too much as they're close in efficiency.

This is like a 30% difference in efficiency, not sure that is very close (unless my math is wrong, it is early)

its actually about 20%. 400 vs 480w

S9 spec:
Power Consumption   1078W +10% (Batch 22 11TH) (at the wall, with Bitmain’s APW3 PSU,93% efficiency, 25°C ambient temp)

T9 spec:
Power Consumption   1450W  +7% (at the wall, with Bitmain's APW3 PSU, 93% efficiency, 25°C ambient temperature)      

I am still trying to figure out how this is a good thing  --or--  how I can convince myself to buy T9s?    Huh
Well if you find cheap used S9's buy em up, else if you have slightly cheaper electricity go for a T9. Really your choice here, I'd personally go with the S9 as there is no proof of better workmanship on the miner or better underclocking of their chip as of yet on the T9. I'd hold off on the miner until reviews get to the forum.

With t9 at 1450w it is going to use 90% of the bitmain 1600 psu capacity.
Should be 80% for safety.

I'd have to check again but I didn't think it was that much of a difference. Remember the T9 is cheaper by ~$100 too.

i think they figure the reason of high S9 hashboard failure
it's the power needed for the chips!
so they produced T9 with 180 days warranty
each T9 board have 57 chips instead of 63 and need 480W to power instead of 400W
less chips more power!

They just announced T9 miner (11.5th/s) with less efficiency at 0.126 J/h+7%
https://bitcointalksearch.org/topic/bitmain-launches-the-new-antminer-t9-bitcoin-miner-1755286
similar setup to early s7 and  late s7 (less chips, less efficiency); here they separated S9 and T9 (less chips, less efficiency).
Good for those who has functional S9-those will be sold with some premium from now on.

you are paying 3.5% extra bitcoins (after you probably gave 3.99% extra $$ to coinbase for a cc purchase+possible extra cc fees)

I've never purchased BTC, I'm using coin which I mined years ago. Bitmain appear to follow closer to the BTC-e price.

While I'm not happy to pay a premium, I do take comfort in the knowledge that Bitmain have a track record of delivering product and the use of escrow isn't required, plus the fact that it's difficulty to find second-hand sellers willing to send ex USA.

coinbase price $838, bitmain's price $809/btc.

I would not buy any miners from bitmain, unless it has an accurate price.

I am interested in buying s9 from bitmain.
Have anyone seen s9 recently in bitmain shop and when it was?
Alternatively other good reputation  places  with bitmain price (not more than 1300USD) 

I had also been waiting on Bitmain to release a new batch of S9's, though I decided to buy into the R4's as they're now available.

Cost per T/H is very similar, USD$130 per T/H for the R4 which had an increase since the last batch. I suspect if/when the S9's are available they'll also see an increase of similar value. I elected to go with the R4's and they appear to have increased cooling capability which hopefully translates to higher availability which equals quicker ROI.

You won't find an S9 that cheap unless it has damaged hashboards

Amazon is more strict than Ebay.  Amazon uses customer is always right approach.  Refund/Chargeback/Dispute they accept even after 180 days and amazon will flat out tell you (display in appeal page) its not likely that seller will win dispute.  Thats why Amazon, many seller comes and see high retail price thinking better profit, then realized you are so deep into the red after a few disputes a few months into it. 

Amazon has so many different programs for the seller tho.


Selling on Amazon definitely is high risk. I have been burned a few times selling old gear there by the many scammers. This certainly is one of several reasons prices are so high on Amazon/Ebay

Was selling a few s7's on eBay.
Turns out that there is a drop ship company in Newcastle DE that buyers out of the country send to.
At that point the item can be shipped all over the world.
Then the buyer will ask for a return or more items than were actually purchased.
So be careful with buyers with a Newcastle DE shipping address.
eBay knows about this scam and location.

How does this drop ship scam work?

I just sold some items in the US on Amazon to a Canadian buyer who is using drop ship in Portland, Oregon. Should I be concerned about a possible scam?
I think Amazon is different than eBay, more protections.
eBay buyer protection is invalid with dropship.
If there is a problem it is harder to resolve.
