I just looked online and Bitmain is having a sale on the S9 and T9+. A 14TH S9 with power supply is $1864 but you can buy T9+ 10.5T with power supply for $855. You could buy 2 T9+ for $1710 and have a total of 21 TH/s. I did the calculations with my power cost of $0.064 a kw at the current rate of BTC I would generate about $289.97 profit a month with the 2 T9+'s as opposed to $219.48 a month profit with one S9. I would ROI in about 6 months and even sooner if I got a hold of some good $200 coupons.

Am I missing something? It doesn't seem to make sense to buy an S9 at the current prices. 

If you are short on power or space the S9 might work out better.

Depending on my locations I have both issues.
1 spot has just about unlimited power (200+A of 220v) for me to use. So long as I can fit it in a 1/4 equipment rack.
The other my "warehouse" has as much space as I want. But with a little less then 40A of 110.
So yes in theory you are correct. But for me I would have to sit and do the calculations as to which would work better for me.

ROI is beautiful in these T9 and from what i have read they are very reliable, they lowered the price to 755 with PSU. If you have 420$ coupons u cant beat that ROI. My power cost is around 0.05$

Your ROI calculations are off you are not taking into account raising mining difficulty. Also shipping is kinda expensive around 110$ per miner i bet you can find some 420$ coupons for around 50-80$

It makes sense buying a 14th/s S9 if u dont have cheap electricity, they are a lot more efficient...

T9 looking like an absolute bargain, im wondering whether these prices may go back up when the BTC prices returns to 15k+?

Wonder why they didn't call it the Q9 instead of T9 since Q is before R and S.

Its like BMW releasing a new cheaper, slower, less luxurious car and calling it the 9 Series.


They called that like that mate for a good reason i guess. Hope many would profitable with this miner , interested with this one too but still don't have some capital.

Thats a huge /when...

But i guess they will sell pretty quick if the ROI gets even better

I bought 20 but it is a weird spot right now to buy, seems like there is gonna be a new miner from Bitmain at any momento, but at the same time from what i have read around the next jump in miners wont be that high maybe 20 th/s not like the S9 vs S7 4th to 13 or 14

wow they're such a scummy company, had the t9 listed yesterday and was 30 bucks cheaper with the ability to use $400+ coupon.  Now I cant even use the coupon and the price has increased along with shipping, knew i should have gotten it yesterday.

I'm in the same boat as you. Was about to pull the trigger with my 420 off coupon. Hopefully, they'll allow their use of the T9 like they advertised...

Doubt it they're a scummy company with no morals lol. I swear they don't want to see anyone make a dime of them.

I'm definitely going to try these out. I'm hopeful the decreased efficiency is offset by increased reliability.

Update:
Reliability has been great! Not a single failure from the first batch. Reminds me of the S7s.

Update #2:
We've got another 50 T9s arriving the first week of March. Check my signature if you're interested.

Is the reliability that  much worth the loss in efficiency ?

I wonder how it will be if I trying to buy T9, my electricity fee is around $0.12 / kw but unfortunately, I don't know much about how to calculate the fee in a month. the shipping is too expensive but maybe it could worth if we can get some coupons to buy. I think it will worth again if bitcoin price can increase higher.

I think it will worth again if bitcoin price can increase higher.

$0.12 / kw is your price per hour. The T9+ consumes about 1440 watt per hour, so your hourly cost for operating one T9+ is going to be $0.1728 (Daily cost is $4.1472 and monthly cost is $124.416). Currently the T9+ makes around $5.83 daily (~0.00073 BTC). You will make around $50.484 monthly after electricity assuming that network difficulty and Bitcoin price will stay the same. Honestly, in my opinion I would rather buy bitcoin instead of buying the T9+ in your case. You can make the final decision but don't forget to factor in network difficulty and future bitcoin price.

Hope this helps. Merits are appreciated.

In my experience, yes.
Not to say the T9+ is super reliable, but more that the S9 is very unreliable, especially ever since autotune.

Are the T9+'s a good investment at $1500 including shipping. They same to be quite more reliable than the S9.

Not at 1500 considering they were selling for less than half that if you had a coupon, and they're still in stock direct from Bitmain. I'd suggest trying to find a coupon and buying direct from Bitmain, as they are currently going for $771 with a PSU. They ship out in just a few days (21-30 of April), and even though customs may be a bit of a hassle it's still better than paying double for one.

You're going to break even in just over a year if BTC prices hold and difficulty also holds. The latter is extremely unlikely, and because of that I would suggest against it. Difficulty's going to kill you in the long run and draw out your break even time by a lot. Coin prices may rise, but you can't count on that when mining.

Tbh i guess bch should rise by the end of summer.
