Hey all - just getting really interested and invested with bitcoin mining. Late, I know, especially with my rank and time I've spent here.

At this point, I think I have a general understanding on bitcoin mining and I was taking a look at Antminers, specifically the T9+ vs. S9-. Comparing hashpower, two T9+'s outweigh the S9-, and equate to similar prices; is the only reason that S9s are bought more often due to power consumption (2x miners vs 1x), or is there something I'm missing here as well?

Thanks in advance.

There is no "s9-" its just the S9.

One of the most important pieces of information to know about a miner is its power efficiency. The T9 plus is way less efficient than an s9.

For example, a 14th s9 uses about 1400w. With $0.10/kwh power the s9 will cost $100 a month to run and produces a profit of $150

A 10.5th T9+ uses ~1530w. With $0.10/kwh power the t9 will cost $110 a month to run and only produces a profit of $80

So a pair of T9+ will only make about the same amount of overall profit as a single s9, hence why the T9 is half the price.

Not missing anything, that pretty sums it up.
The one thing you *are* missing though is reliability. When they 1st came out the T9 (not T9+) was more reliable than the s9, only slightly slower and slightly more power hungry the the s9. More to the point the T9 is no longer more reliable - yay Bitmain...

Personally, now the only miners I buy are the Avalons from Canaan.io
Very very few problems reported with them, 2-year warranty and even better -- if something does go bad Canaan will send you the replacement part unlike BM that requires you to send the whole miner back to them.

Thank you both!
