Hello, if you tell me where to look i'll tell you. Unless its on the Controller, not the PCB. The controller says 1.5.

I got me a second hand miner; I'm glad they do still offer the option because I move a lot of product and S5's are a hot commodity right now.
Plus, there's my own mine I need to upgrade constantly.... but I still run S1/S3's still.
It's like buying a second hand car from the OEM dealer, they will give you a problem free car... or as close as it gets.
I like this better than new because you save a bit off day one and the unit came off of a production line; working the same day it was boxed.
So I know I get a working tool... cuts away from DoA's or outright lemons.... which happens a lot in this industry, not just Bitmain.
I wished Bitmain had done that on S3's..... I don't think I'm going to sell any anymore, they are prolific AltCoin block finders.

The problem for me now is that I still need to buy the BTC. I need approximatively 1,5 BTC but with credit card it's problematic :/.
No one you can buy Bitcoin from, or not ready to afford the cost on services such as Circle?
Not everybody lives in the US.
I live in France, there's a service which is equivalent but which is limited to 100€/week/user. Plus it needs to have the 3D Secure enabled, something I don't have.
Well then come to #cryptofr on freenode, i'm sure several users there can help you.

I don't live in the US. So that's not a very good reply to my comment. If you elaborate then maybe i/we can help.

Look like you were right.

Bitmain might be switching "batch shipping date" again, there was about a day gap between when they finished up the sales on the "August 5" batch and started sales on the "August 14" batch where none were shown as available. Check back again in a few hours. If none are up for sale by the end of tomorrow, things MIGHT get real interesting.
They might also have messed up the website a bit when they added that wierd "PACMC" thing, and they're supposed to be adding the S5+ tomorrow to their main site.

are they gone...
I figure there will be a jump in the month before the halfing - based on speculation.
I dunno if the price will STAY higher a couple months or more past that though. Some of the jump might stick, but I'd hate to bet on all of it doing so.
Longterm, I believe bitcoin will slowly increase in price - possibly even beating inflation.
There is of course the possibility of someone with a large number doing a "dump and pump" or "pump and dumb" and bouncing the price at ANY point, or multiple points.

According to supply and demand theorem, if the award is halved then the BTC price must be doubled.
There is an already existing LARGE supply of Bitcoin though, the block reward just adds a very small amount to the supply.
The pair of used S5s I got from Bitmain were clean, and in generally good shape. The shipping packaging wasn't great, but the only damage was a couple of fins on the bottom of each heatsink bent up a little, trivial to "fix" and would probably have worked OK without "fixing" them.
while 14 or 15 million bitcoins are mined.
Many are lost.
Many have been frozen in place for years.
So to think the available supply is 14 or 15 million is wrong.
I would think at least 1,000,000 are frozen and not available.
I would think at least 1,000,000 are lost.
And of the remaining 12-13 million many are being held as speculation.
Try listing the top 10 exchanges and you will see volume of a few million tops. So 7000 coins each day vs 3500 coins after ½ may be as much as a 2 to 5% each day. So 20 to 30% price jump would not be out of order.

Hi everyone ! Today I saw that Bitmain was selling S5s for 391 USD. But they have already been used. Is it a problem ? What are their estimated lifetimes ?
they guarantee that its working (minus a few scratches), and all my experiences with bitmain have been good. the profitablity on the s5 are very good... for now
I received mine.
Minor and Potential issues aside, the unit perform well, and is very efficient. Overclocking a bit does not reduce efficiency, it actually improve it by a little bit. I'm running longer tests now but i think this is because the Hashrate/W efficiency stays the same but the fan does not run faster, so there is a very minor efficiency gain while overclocking to up to 400~
Also its loud as hell. I posted a graph with numbers if you're a number person.

Thanks for posting and letting us know what this "used" batch is like. It is a interesting batch to say the least.
And yes the S5 has some sound and heat to it. It is not made to be in a area needing a quiet miner really.
Mhm, i'm hardcore however, i am running this in my living room, along with other stuff. xD
Anyways, the summer is ending fairly soon, thus in 2 or so months i'll be able to just open the window to get an ambient temp of 10C, at which point i can use stock fan at lower speed and get very low temps.
But for the next summer, I will have to go with the mods i've seen. The one that make them near silent and much cooler than stock fan running at full blast. Maybe get some printed enclosures too.
