Main point to keep in mind is that when sizing ANYTHING electrical is that you must NEVER have a constant long-term load exceeding 80% of what the device (or wire) is rated. This applies to wiring, circuit breakers, stabilizers/UPS's, ect. The short form is to take your miners' maximum power rating and add 20% more then pick a stabilizer rated for at least that power, preferably substantially higher. eg for a miner rated 3,500w the stabilizer should be rated for at least 4,200w.

^^  >99% of the time cloud mining is a Ponzie scam. I am unaware of ANY legit ones. You *might* initially see some rewards (actually paid from new fools signing up) but sooner or later the company either disappears, changes their payout terms to make it unprofitable at all for you (Bitdeer does that), or otherwise screws you.

Hosting can work if you use a reputable company with good rates for the power used and can afford to buy the gear to run with them.

If you had bothered to read this thread you would have seen that, yes, they are immersion ready.
Very low noise but you still need to get rid of the heat.

And I have a Unicorn that flies and spits diamonds...
Show proof/examples and a repo location.

any DECENT pool will include all tx fees as part of their distribution.

Don't see knots as a needed option. Query: Why would you think the pool should change to it?
From his past and present interactions with them, Luke Jr has ticked off many of the OG devs. Also doesn't help that his bgminer is a ripoff of cgminer...

Is the drive a bootable one or just a data drive?
Being from 2012 any mining would have been using Bitcoin core and CPU miner or maybe the later GPU version (which btw is what -ck and Kano later based cgminer on). Dedicated FPGA (no ASICs yet) were pricey so doubt those were not used. Either way you need to find the wallet.dat file as that where any coin addresses will be found.

Also does not help that you use yandex.ru
Anyone using a Russian services provider is right out for me.

Old news... It was a very large rental on solo.ckpool a 2 days ago. https://bitcointalk.org/index.php?topic=5237323.msg65756404#msg65756404 As said before, it is NOT exactly a rare event.

Slow is true, inaccurate - bull. When a post has invalid info it is soon corrected by folks with better knowledge on the subject.

And regarding even what should be very basic questions, AI answers are also VERY often embarrassingly WRONG.
eg, Q: "What is bitcoin mining?"  Usual answer is "mining involves using specialized computers to solve complex mathematical equations" which is 100% wrong - BTC miners are brute-forcing a solution using gazillions of sequential random guesses, there is no equation solving involved.

Without someone to step in to say, 'ehem... that ain't right' you can be pursuing incorrect solutions.

No. All it does is reduce the number of shares being reported to the pool. That in turn makes it harder for the pool to determine what work dif to send to a miner causing wider variance.

Personally, if you are afraid to carry fiat I'd move to a different area or country or at least take some self-defense courses...

In the US I have zero fears about carrying fiat. That does not mean that robberies don't happen here - of course they do but is it is definitely NOT a widespread problem and in any given city, given the huge numbers of people in them is actually pretty uncommon.

@OP: you do know that when talking about millionaires/billionaires they do NOT have that amount in cash right? The vast majority of their wealth is in various holdings - stocks, bonds, real estate, etc. To do what you are thinking of would require them to sell off most if not all of their holdings to then buy BTC with the proceeds and that is *not* ever going to happen.

Since the OP seems to ignore the DOZENS of existing threads on this very subject and decided to create yet another one - ignore button now active.

I really don't care. BTC was never intended to be private and folks who have an issue with that should find a different coin to use.

I do hope that it is not shut down. Bitcoinity has been my go-to for checking prices even since I started in BTC so very long ago.

For a start, I suggest you 1st go to Beginners and Help area and look around there.

2: This area is for Bitcoin only - NO altcoins. Go to Mining (Altcoins) for for discussions about Kaspra miners.

3: Check out the LOCAL areas to find one in your native language.

Not going to happen. What part of BTC using a public blockchain do you not understand? Change that and it would become just another crapcoin fork and no longer would be Bitcoin.

Glad to hear it  Merit given for getting back with results.

@OP: please read and comment in one of the NUMEROUS existing threads on this. We don't need yet another...  

And personally, myself and many many other knowledgeable folks here do NOT think it is imminent danger from QC. Yes eventually something will need to be done in the coming decades but not right now.
