What's worse is that some folks think it's not just ok but part of their vegan mission to force their pets to be vegan...

Hate to tell ya this folks but cats, dogs, most lizards, many birds, et al are either carnivores or at best, omnivores that prefer meat but do also occasionally eat plants when needed. They simply will not get the nutrients they need from only plants and will often practically starve themselves if not fed what they are born to eat or at least something resembling it.

The main point of mining BTC is what it has always been: To confirm transactions. Something cannot have (verifiable) value if there is no way for 2 or more parties to confirm the exchange of what they are trading/buying/selling...

It just so happens that because BTC is not a centralized service (or coin) ran by a company that has their own data processing centers like the credit card companies and banks do, all transactions instead run through and are stored on a public blockchain and the equipment used to verify the tx's is owned by miners.

How does one encourage others to spend $$$ to process the data? Pay them rewards for the work done that are worth more (in fiat) than what it costs the miners to purchase and operate their equipment. Things don't get much simpler than that...

Only trick is that you will need the 'paperclip trick' to turn on the PSU. If you look at the large mobo plug you will see a green wire in it, use a piece of wire or bare metal paperclip to join the green to one of the black wires next to it to turn on the power.

Well, Inno's main business site is back up https://www.innosilicon.com/ but nothing regarding miners anymore...

Their main business has always been custom ASIC design services. They got into mining chips in 2013 when they did the design for the 28nm A1 chips for the now long defunct Bitmine.ch. Once they saw how wildly profitable making miner chips is -- they also designed the chips used in Dragonmints - and the rest of the hardware is when they launched their own line of miners.

Wonder if they've now gotten out of the mining chip business to focus on their core business once again?

For what it's worth, a short while ago we hit a new ATH of $64.34k USD  
My guess is that the shipping companies are running smaller loads so the ships can be offloaded faster so they can move on to other ports. Other news items from that site reference that many shippers have had to cancel routes because of the delays...

Both the controller and miner (mm) firmware are here https://download.canaan-creative.com/avalon921/ Just use the latest for both. Of course, until the AUC and miner are actually seen by the controller you cannot update the mm firmware...

Ja power should be ok using an 1,800w PSU but is not 'quite enough' as I've measured mine to pull just over 2.2kw running full speed in a hot area. In a rush to be the 1st to market with a 10nm chip miner Canaan and the foundry they used (Samsung) rather blew it on the power/speed specs. The 921's are actually slightly less efficient than the venerable A841 is which used 16nm chips.

re the AUC not being seen, try a different USB cable. Many are charge-only cables that have no data lines so look for one labled 'charger + sync' or something like that.

Of course they are colluding - Bitmain and other miner mfgrs also own several large mining pools... As to them actively working to keep diff low - doubtful but if they are, works for me!

Who the fuck is Jamie Dimon? Never heard of him. Even if I had, I make my own decisions and they are not based on what some random public figure(?) has to say
That said we should not care the least what he says.

Hopefully they just went offline until they resolve the problem of them shipping miners that are locked. That said, a better way would be to have the site up with a notice and no sales from it.

No, they will probably make no money. Then again these are aka "Lottery Sticks" because there IS a chance you might get a block from a solo pool. In that case -- cha ching!! If you sometimes buy a lottery ticket then ya might as well go for a stick to try your Luck because at least they are dirt cheap to run.

Just look through the Support area to find the issues people have had with Ebang miners. There is good reason very few people use them: They have horrible quality, even below Bitmain's S17's - and those are pretty bad with over 25% failure rates...
Customer service is non-existent.

Do a search using "software defined radio modules" One good link that pops is https://blog.bliley.com/10-popular-software-defined-radios-sdr
#7 in that lineup looks good...

For a start, do you have a big enough PSU powering it? The 921's will pull from 1,800 up to about 2,100w. Available settings can be found here A little further down on that page see https://bitcointalk.org/index.php?topic=5085231.msg48793403#msg48793403

A screen shot of the cgminer status page would be of great help to let us see if the miner and AUC are even seen by the controller.

When you downloaded the OpenWrT controller firmware did you also get the matching miner mm firmware? The 2 must be the same (latest) versions.

re: Nicehash, NH requires the miner to support the stratum call #xnsub to allow it to seamlessly switch the miner to different coins or work orders. Problem is that #xnsub is a security risk as it allows the miner to run any subroutine a pool sends it. Because of that risk Avalons do not support #xnsub.

And if he had died from the Flu would you then say that flu shots are ineffective? Guess what - NO vaccine is 100% effective but most certainly do improve your odds.

re: tvbcof's bile, ^^
And the fact that Iraq had been invading its neighbors and killing their citizens should have been ignored? Just how long do you think you would have lived in that country if you were spouting off like you enjoy doing? Ans: Not very long at all, you'd be among the 1st lined up against a wall shot and then hung from hooks.

Ja it turned out that Saddam was bear-baiting the US and rest of the world regarding bio-weapons but nonetheless something had to be done about him. I take it you would rather have let Saddam run rampant like the murderous lunatic he was?  At least Qaddafi learned his lesson and took Libya away from the road to destruction he had been leading it down.

So much for this thread being a respectful obituary for someone who was a very fine soldier...
I for one salute his memory

Instead the anti-vaxers have once again taken a sad occurrence and are using it to promote their views. Shame on you!

One has to just love how ignorant or at best, naive many folks are...
This is a legal question. Do they honestly think that all countries have the same laws and financial regulations/definitions? Hint: They do not. In the US, what is considered common property in marriage/divorce even varies from state-to-state.

As the OP's questions stands, the only answer that can be given is what other posters have said: It depends on where you live. If you want an accurate answer, at least let us know what country you are asking about...  

And hopefully also reiterated the plethora of ways criminals get around 'controls' the banking systems are supposed to have. They know damn well that there is far more money laundering done using fiat than crypto and things will remain that way for many many years to come.

No let's NOT say it is a scam.
Fact is that BTC is NOT a scam and is becoming more and more widely accepted even by governments as a legitimate and legal thing. Scams are not regulated as they are illegal. Only legitimate financial things are regulated (and taxed).

Facts be facts, all discussion of this topic should have ended many many years ago... 

NEVER use 2 different circuits to power the 2-inlet PSU's!
In theory if you lose 1 line the miner should simply shut down but I would not bet on that happening before the PSU is damaged...
