Um Bitcoin mining cannot be 'ran with a smartphone'... Sure you can mine crapcoins like monero but BTC no way, no how. Since 2014 it has been out of reach even for the best GPU rigs much less a phone.

Then again, maybe you think all crypto is Bitcoin? If so you are dead wrong...

Lovin' these prices! Coinbase showing $44.9k 24hr high and currently at $43.39k.
Sold a bit the other day at 38k and now just waiting for the dip hopefully back to around 30-32k so I can buy in with more
Looks like this is why todays prices is so good https://bitcointalk.org/index.php?topic=5315588.msg56298335#msg56298335

Bullsh**
*can be used* for nefarious purposes, yes however, Bitcoin uses a public open ledger with all transactions easily seen and tracked between addresses - hardly 'untraceable'. Now some altcoins - that is a different story.

No matter what coin is used sooner or later conversion to/from fiat WILL occur which brings up the very large elephant in the room which is the fact that fiat is the 'root of all evil' and prime currency used for illicit activities.

@OP
Please change the title of this thread. The US Navy is NOT who did the alleged crime(s). Your title is pure clickbait at its worst.
It was done by Marquis Asaad Hooper and Natasha Rene Chalk who at the time were members of the Navy which is a helluva lot different than what your title says.

A more accurate title would be, "Former US Navy personnel sold 9,000 personal data for Bitcoin". That is just as eye-catching for clicks while also being 100% truthful.

Good link about recovering data from SSD's
Link to problems that HP drives had after hitting 32,768 hrs of run time
IMHO the best and most trusted data recovery firm (NASA used them to recover almost all data on the black box drives from the space shuttles that were destroyed) They have been in business for decades and have several labs around the globe you can send the drive to.

You do not/should not mine to the node! The node is simply there to support the Bitcoin network by well, having another full node on it for storing/distributing blockchain info. AFAIK the devs removed the solo mining function from Core several years ago.

Be it solo pool or normal pooled, mining requires the pool you are mining at to have the fastest possible connections to the BTC network along with wide distribution of that access to be able to monitor chain activity for block changes and notify the network when you have found a block. That is not an out-of-the-box thing to do.

Good question. Considering that electronics shipped to the EU must meet specific labeling and material (no lead allowed) requirements I have to assume that like Sidehack did there will be EU-specific variants?

Query: Are the miners and laptop using DHCP or static IP addresses? If they are static addresses perhaps the laptop is using the same address as your router or a miner and causing a conflict somewhere.

Nope. There is not a secondary market for new vs used or possibly 'dirty' BTC (yet).
Also, 'mining non-KYC Bitcoin' is simply an eyeball catcher tagline. Unless you mine on a pool that requires KYC, all newly mined coins are non-KYC. More to the point - who the f*** cares? New coins are new coins regardless of where they were mined - end of story.

That is mostly it. Thing is, some folks also have issues with setting up Ants and those are as simple as it comes... With the Avalon's the spot some folks have a problem with is either burning the SD card or dealing with the initial default static IP address. What I do is:

 burn a micro SD card
 change your PC LAN connection to use 192.168.0.101 or any address on the 192.168.0.xxx range EXCEPT for .100
 plug in the micro SD card and fire up the controller with it
on PC log into 192.168.0.100 and change pool and user settings to what you want
 change from static to DHCP or set a different static address (I prefer DCHP)
 Save and apply changes
 Power off controller
 remove SD card and plug back into card reader
 read card and create an image file with the new setup
 Then use that new file to burn cards for your other controllers

Plug sd cards into controllers and power up. Now being DHCP look for the controller on your router and log in to check miner operation.

As for temps, the Avalons have a few ways to deal with that. In the more options field you can use --avalon8-temp <nnn> to have them throttle back to hold at any temperature you want. I've ran mine up to 42C ambient temp without using that temp limiter with the miners reaching 105C and no problems.

Just refer to Hagss setup guide for the A8's and you should have no problems.

The point of testnet coins is spelled out in their name...
They are for testing algorithms and mining software operations without endangering the main coin networks and are most often used when folks are coming up with a new shitcoin. Putting a monetary value on them defeats the whole point.

I agree wholeheartedly with the OP. As most of my posts reflect, I always prefer to teach about a subject and encourage others to learn the how/why of things vs just giving a single answer.

Learning the how/why lets you understand the reasons behind something and that will hopefully give you insights into other questions you may have on a subject.

Good question.
Posted it to Kano in the Discord room so when he gets up later we should get a solid answer because IMHO he has better knowledge of how the software side of the mining process works than anyone else in the Forum - specifically, how cgminer operates and pools interact with it. I asked him:
I'm thinking that it's the latter and there is a 2nd hidden/background IP connection being made similar to have multiple tabs open in a browser. If so that would explain his always referring to xnsub as a (potential) security hole and not a feature. Also asked about #xnonce.

In many ways this is touching on what Slush's "Stratum V2" is aiming to accomplish - in a sense make miners more 'multi-threaded' vs doing just 1 thing pointed at 1 IP address (pool).

edit: I thought this was familiar territory - seems I was in a short discussion here about it a couple years back Further google searches turned up references from Mining Rig Rentals and a couple other rental services about needing the "NiceHash #xnonce cgminer patch"... Search using  "stratum #xnonce"

I used 'periodically changes' as a simple way to describe it. They use a stratum security hole 'feature' called xnsub to seamlessly redirect where some shares are received from/sent to (DevPool) without actually resetting/restarting a miner like changing a pool would do. The effect of using xnsub in that manner does not show up on any miner GUI or monitoring software as all it knows is that the miner is hashing at x speed.

Aside from dev fees, the main use of xnsub is to allow rental places like NiceHash to have (rented) miners point to wherever the person renting it from them wants without forcing the hardware to constantly restart. Another example would be if you point a SHA256 miner at Slush and let them mine other SHA256 coins as well as BTC, again, xnsub lets them switch the work between different coins w/o restarting cgminer.

As to modern miners all using custom PSU's - ja I see that as a major 'gotcha'. Aside from the higher efficiency gained by eliminating secondary on-board Vcore regulators, the only other advantage to them is eliminating the field of PCIe power connectors that can often burn up by replacing the power connections to hash boards with solid bus bars. I'm rather surprised that no PSU manufacturer has stepped up to address that point. After all, it is simply a programmable PSU that either responds to a 0-5v signal or I2C command to set the output according to what the controller tells it to put out. All the PSU maker needs to know is the input commands used, expected voltage output range and max wattage.

edit: as Mikey pointed out later, it was (probably) xnsub - not #xnonce I was thinking of. Corrected that. Thing is, #xnonce does come up on searches as being similar crypto function. Move further discussion on this to https://bitcointalk.org/index.php?topic=5312770.msg56205843#msg56205843 which Mikey started up as we are getting OT here...

Ja, however, set the 841 to low-power mode and in the More Options entry box use  --avalon8-fan 10-30  and it becomes a more efficient and quiet space heater. Will give 8.3+ THs and pull around 750w while being quiet enough for use in an office or TV room.

I'd say take it. The 821 is only about 1-2 THs slower than the 841 though again, remember you cannot mix different models on 1 controller.

Regarding the mention of 3rd party firmwares for s9's - keep in mind that most charge you a couple % usage fee that is taken by the miner periodically changing to what is called DevPool. The Avalon's have no need for those 3rd party firmwares because they already support an extensive list of built-in performance tweaks to change clock rates, chip voltage, fan speed, operating temp, etc.

Do NOT click on any links in the emails as they will probably attempt to load malware on your system!
Then tag them as spam so they go into your spam folder to eventually be deleted.

If you are doing serious video editing forget ANYTHING for mobile devices... You need a good PC with multiple monitors, lots of storage and ram.

I use a 6-core i7, 64GB of ram and 2TB ssd's to run Sony's Vegas Movie Studio. It is a very reasonably priced studio-grade package allowing for multiple simultaneous HD (up to 16k resolution) input sources, mic location syncing to video, ACID loops for background music, etc.

I have no experience with the 851/852 so not sure about their speed or efficiency. Frankly I'd get the 841's, main reason is that there is a ton of PSU's out there for that power range. Max a 841 will pull even when over clocked is under 1,500w. As I recall the 85x series push 1.5-1.6kw and I know the 921 will pull up to 2.2kw

Highly suggest you peruse HagssFIN guides on the Avalons:
841 guide & review
851 review/guide
A7xx & A8xx troubleshooting and repair guide

Sorry to hear that. I take it you are in Asia? I know several countries in that region of the world are exceedingly harsh on it. Considering that it was the US that created the anti-cannabis mania back in the 1930's and pretty much convinced other countries to follow their lead, hopefully with the US now slowly removing laws against it more countries will again follow the example and remove their often draconian punishments that users can face.
