I don't understand the lamentations about a lower price. If you bought higher I get it, you feel like you got jammed. But that's the breaks. As far as how it will affect mining, it's good for mining as far as I can tell. Listen I noob paid 4700 for my first s9 in December on the secondary market and I'm not complaining. They went up to 6500 after that, and I felt pretty good about it. Now they're less than half that, but what if they didn't drop? Who knew? You take your chances. After my second one at 1850 usd I told myself I paid 7k for 2 to make myself feel better Grin

More miners, more machines in spare bedrooms and garages and sheds all over the world, let's get it going. I don't see the problem.

Me too, noob paid usd$4000 for E9+ in Jan, and usd$2320 for S9 and value paid $1188 for M3.
Average them out and feel slightly better.

But the problem is, btc price stagnated and under-valued, plus hashing difficulty increases, whereas the electricity cost is still high for me. Plus the shipping cost, taxes and hosting fee, I am running the miners at a loss right now.

Was very tempted to get 1 more S9 but it would seriously undermine my relationship with my missy now Sad

Bitmain could be trying to crush the competition as their miners are now much cheaper than all the other miner manufacturers and the efficiency is about same as all the others have caught up.

I suspect thats part of the reason. But things can still work out somehow. The D3 was bad but the antminer A3 was well handled. The first A3 batch users have already broke even. I hope that all miners will be well handled. The fact that they give out coupons and gave fair options to early X3 buyers also tells me they can find solutions too.

Just my 2 cents.

Welcome to the decentralized mining age

thetaj buddy,

The antminer S9 just got its price reduced in new batch. Those that bought at 1.6k and 2k+ just 2 months back would have been better of if they bought now. What do u think would happen if future batches become cheaper and cheaper.

Look at the D3 now, the last batch was 318 USD. Previous batch was 550 USD. The batch before was 1.45k, and then 2k-3k+ and first batch was 5k+ ...if i recall right.
Point is the D3 now makes Negative 20 dollar profit at 12 cents electricity. It makes negative 4 bucks at 9 cents. It makes 23 bucks at 5 cents electricity.

Now buddy, tell me wat u think will happen to S9 mining profit if the S9 keeps doing the same D3 does, getting cheaper and cheaper batches all the way to the few hundred dollar per miner range?

it is too bad that an "entity" can really manipulate and have that huge effect on the industry! shame!

Can already feel the pain with mining as reward is lesser and lesser even with a medium size farm. For people who are starting now, getting tempted now with low prices and expect profit... well... good luck.

I wont call it manipulation. I am aware this is just business. Last year btc price rose 10x, asics sales boomed. Btc price is not rising 10x this year, like last year. It isnt possible to rise 10x yearly. Btc market cap would go to 1.33 trillion and then 13.3 trillion in 2 years. Not possible with gold at 7.8 trillion mkt cap. Thus, I hope they can downsize their production capacity. Last year was an anomaly. It wont be sustainable because btc market cap cannot rise at that rate. Dear bitmain, some of us have already unplugged our D3. We will not break even on the D3. We dont wanna have to unplug our S9 too.

With this pricing strategy, only the newest batch would be good, until a newer cheaper batch appears. I hope bitmain also finds a solution for their older batch supporters and future mining profitability.

Just my 2 cents

Math doesn't care what you believe.

Yeah, the L3s I bought at $1270 with coupons are now listing for $855. Considering mine have not shipped yet, and you can't cancel an order with Bitmain, feeling a bit, ah, "worked over".

14TH S9s now $1365, a new low for them.

I too bought 10 units a few weeks ago for 2500 shipped each after all said, and done. Then they sold 14th models for 1800+ with PSU! I am really pissed off, and I can't even sell my unit to break even, and it will take 13-14 months just to cover the cost of the miner even with my per KW rate is .06 cents and no rent. Sad

I feel like the only option now is to run them..don't really want to sell for a loss, when they are brand new, and just arrived. Sad

Just dropped the price again today. Shocked

Created AutoTune to saved the planet! ~USA

Make a box in the windows then duct into the box and put a big fan in the box pumping air out. That is what I did and was able to hookup 20 antminers to a small 1ft by 1 ft window.

Hello experts,

Need to get your advise on something.

did any of you tried connecting 2 S9s to 1 5" exhaust? I am running out of space and need to "combine exhausts".

I am using a 1.5m length 5" ducting for each S9 and it appears that the 5" ducting can support more air flow as it is not that strong.

Thanks.

Couple of things, I used larger ducting to allow more air flow, and used PVC Tee pipe connections and in line fans to move the air.

Then an inline fan to pull the air flow. Use as short of HVAC tubing as possible, more air pockets the more your use. For inline fan, it takes about 250cfm (cubic feet per minute) per machine, so this fan below should work for three machines.

Yes, you can merge vent loines but don't let air flow get trapped

Man, really could use lower difficulty anf higher bitcoin prices or a good new sha256 algo coin to mine right now. It is getting tougher.

BTC failed to test the $8300 support level. seeing another bloodbath.

It will bounce back I think. We cant afford another bloodbath...

I feel like BTC needs to be about double what it is right now for mining to be ok. If it goes closer to $6000 I'm probably going to start unplugging machines and I have .08 kwh electric. It's just not worth it. All those guys with high electric like .35 kwh tier 3 have probably stopped mining already. LCC is another sha256 coin option but probably not better at the moment.

I think I'm going to buy 4 T9+. I have 4 good coupons.

hashrate /price is good but require double the power.

I am also considering the T9's provided the price right now. What do you mean by double power? Aren't they the same power as S9, but just lower hash rate (and supposedly more stable).

I think he means that as you need same power to have half less hasrate, you need around 2x more power to match S9 hashrate. So it's ok if you have good electricity price.

I can ~~can~~ vouch for the T9 (first model 12.5 Ths). Have units since the first batch was released (some were never turned off since Feb 2017), faced no issues so far (knock wood), same power supply, just opened once for cleaning. They generate more heat though and consume more power.

U mean your power supply uses more power as time pass by? U sure?

Does anyone is giving away coupon for a couple S9?

Looks like people only giving away the lower end ones that they can't sell. I sold all of my higher end coupons.
