you're in the bitcoin mining subforum, so i'll give a bitcoin mining answer:
look at this: https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison

Even a XEON cpu only hashes at @ 140 Mh/s... 20 of those would only run a less than 3 Gh/s..
Now put this into any "reasonable" mining calculator...

https://www.coinwarz.com/mining/bitcoin/calculator?h=3&p=3250.00&pc=0.0&pf=0.00&d=22335659268936.00000000&r=6.25000000&er=1&btcer=51381.36660000&ha=GH&hc=0.00&hs=-1&hq=1


You'd be risking your employment and being sued for 0.00000002 BTC/day (that's 2 satoshi's!!!). And i'm pretty sure those pc's you're talking about don't have Xeon Phi 5100 CPU's.... So your result will be a lot less...

If, by some miracle, you would get away with such a setup for a full year, you would have made something like 700 satoshi's... Or, at the current preev rate 36 cent... Well, probably a lot less since even an i7 runs at about half the hashrate of this Xeon Phi 5100 (on average... nobody benchmarks these things anymore because it's a bad idear to mine BTC using a cpu). I'm strongly against faucetting, but in this case i'd advice you to find a reputable faucet: it'll take less time and you'll make more money with far less risk of getting fired (unless your boss constantly sees you faucetting instead of working).

Even if you'd mine an altcoin (like monero), an old pc would still make peanuts... Really... Why would you risk getting fired for a couple of bucks? It's just not a smart idear...

I guess you'll have to read the whitepaper....
But no, the fastest miner won't solve all the blocks.

I'll try to give you a very, very, very simplified example:
You have a big swimming pool filled with numbered balls... There are 1.000.000.000.000 balls in the pool, each ball is numbered incrementally (from 0 to 999.999.999.999). Your task is to draw a ball with number 100 or less (that's the difficulty). If you find this ball, you get $1000 (the block reward) and any coins hidden inside the ball (the fees). If it takes to long for a "good" ball to be found, the consensus is that the number 100 might shift upwards or downwards (the difficulty retarget), this is checked every x "correct" balls that have been found. If it took to long for the network to "solve" the problem, they might change the difficulty to "all balls equal or less than 120 are good", if (on average) the time between 2 "good" balls being found was to short, the difficulty might change to "all balls equal or less than 80 are considered good".

By hand, you can check 1 ball per second...
Let's assume you have a machine that draws and checks 100 balls per second (the fastest asic), will this machine be guaranteed to "win" every time? If you are alone around this pool, the answer is: yes... But in reality, the network is open, everybody is allowed to mine, so you won't be the only one standing around the pool, trying their luck in claiming the >$1000 reward.

Now, let's assume everybody is able to buy a ball checking machine (ASIC's are sold commercially you know, everybody is allowed to buy one, unless their governement is quite backwards)... Around your pool filled with balls you'll have a couple dozen people picking and checking balls by hand (cpu mining), you'll have a couple people that invented a simpler machine themselfs and they're able to check 10 balls per second (gpu mining), and you have all kind of people with commercial ball picking machines (asic's) ranging from 50 balls per second to 100 balls per second.

Offcourse, after a while, it becomes clear that the people picking the balls by hand (cpu mining) and the ones picking balls using a homemade device (gpu mining) have a big disadvantage... Since picking and checking balls requires effort from them, they're pushed out of the ball picking (mining) environment in favor of the ASIC's... But it's not because you have the fastest ASIC, you'll win all the time... there are hundreds like you, and hundreds more with slightly slower machines... Your odds are about equivalent to your hashrate devided by the total hashrate (on average).

Now, this is a gross oversimplification... But to a point it is correct...
When you're mining, you're building a new block header using information from the previous block's header, a merkle tree and some other info... But most importantly, it also contains a nonce (which is basically a field that can be filled with random data).
Your ASIC fills the nonce with incremental data at a very, very, very fast pace (in the Th/s range), then it executes a sha256d function on the resulting block header and checks if the result is UNDER the current target (like with the balls, you're randomly picking them and checking if their number is equal to or smaller than 100).
The more hashpower you have, the bigger the odds of finding a header whose sha256d hash is under the current target... But the target is soooo small, that, on average, all ASIC's in the world will take ~10 minutes between finding such a header. Unless you own ALL asic's in the world, you won't be guaranteed to solve ALL blocks. It's like the swimming pool filled with balls: unless you're the only one picking balls from the pool and checking them, there is no guarantee that you'll win every time... Sure, the more ball checking machines you own, the bigger your odds become, but all in all your odds are about your hashrate divided by the total hashrate of all people standing around the swimming pool filled with numbered balls.

I hope this makes it clearer... If not: really, read the whitepaper... There are even simplified versions and youtube videos around that teach this stuff...

What i'd like to ask you is: do you really think a bumping service is doing you any good? Really... If i see a post constantly getting bumped by newbies, without the OP even answering their questions, it's pretty clear to me that you just want your topic to be bumped at any cost... That's why i'll stop replying to this thread so i won't bump it any further (at this point it should still be at the top of the subforum since it's relatively new anyways).

Do you want to know what my first instinct is, when i see a newbie promoting a service AND using a bumping service? My first instinct is thinking to myself: this service must be fake since it relies on a bumping service to get exposure... In this case, i took the effort to dig a bit deeper, and i found out that the pool you link to has indeed solved several blocks, thus it's not fake (eventough there is no proof you're an actual representative of this service).

Want my advice: stick to one thread about your service and get actual community involvement... Stop hiring bumping services, they make you look unprofessional and fake... Oh, and proof that you're an actual representative of this pool...

Personally, i'm afraid of a $5 wrench attack....
It's nobody's business how much BTC i hold, and where i keep it... Eventough, if you're with a community long enough, there'll always be people that know who you are, where you live and whether or not you're a hodler.

Soyoustart has very reasonably priced dedicated servers... You'll have to install everything yourself, and i think plesk is quite expensive, why would you need this?

I guess a VPS with 800 Gb HDD will be more expensive than a dedicated server from soyoustart or hetzner

I agree with everything that has been said, and i feel sympathy for the victims... But the moderators won't do anything about this...

• On forum: scams aren't moderated... And on-forum at least they are being held accountable by the community and sometimes cases get solved because they sometimes (used to) cave to public pressure (at least, that's how it looked to me, not that i have ever had funds on their "wallet")
• Off forum: bitcointalk is just a community, we don't govern bitcoin nor are we lawyers or copyright holders... There is nothing the moderators or admins can do...

No worries... Keep them as long as you have good use for them, if i have them back by the end of march 2022 it's ok... Even after march: if you still need them, you can keep them longer (in that case, just keep me informed).

I'm looking at your excel, but what am i seeing here?
I don't see the difficulty being brought into your equation to begin with (and inserting this is a no-brainer....). I see a column "BTC / Mean Hash Rate" in your DailyBTCdataFrom09Jan2009 tab, and this column is appearing in your other tabs aswell... But the number fluctuates each and every day whilst the difficulty is adjusted every 14 days...

If you want the real number, what you should do is use the formula
BTC earned per day = Block Reward / (Difficulty * 2**32 / hash rate / seconds in a day) (source: https://bitcointalk.org/index.php?topic=726962.msg8233023#msg8233023)

So, you'll have to do this calculation for each and every day, then convert the BTC earned per day into USD (or EUR, or Yen, or ....) and substract the electricity price.
You'll have to repeat this for every single day:

• the block reward costsists of the coinbase reward plus the sum of the transaction fees of every transaction in this block... you can take the average per day
• the difficulty stays the same every 2016 blocks, but then it is readjusted
• your hashrate stays the same
• the number of seconds in a day stays the same
• the exchange rates changes constantly... you can take the average exchange rate for that day

Let's make an example entry for an S17 on the 1st of januari 2020:
BTC earned per day = Block Reward / (Difficulty * 2**32 / hash rate / seconds in a day)

• On this day, the coinbase reward was 12,5 BTC/block . When we look at blocks like https://www.blockchain.com/btc/block/610700 and look at some earyer and some later blocks, we see an average fee of ~0.2 BTC/block (guesstimation, not actually calculated). This brings the block reward to 12.7 BTC/block.
• On this day, the difficulty was 13,691,480,038,694 (https://btc.com/stats/diff)
• An S17 hash a hashrate of 56 Th/s while drawing 2200 Watts (that's 56.000.000.000.000 hashes/s)
• A day has 86400 seconds

BTC earned with a S17 on the 1st of januari 2020 (on average) = 12.7/(13,691,480,038,694 * 2^32 / 56.000.000.000.000 / 86400)
BTC earned with a S17 on the 1st of januari 2020 (on average) = 12.7/12153.7
BTC earned with a S17 on the 1st of januari 2020 (on average) = 0,00104495

https://coinmarketcap.com/historical/20200101/ says Bitcoin's price on the first of januari 2020 was $7200/BTC
This means your gross income was $7200*0,00104495 = $7.5

Your machine is drawing 2200 Watts 24 hours per day, that's 52.8 KWh (let's round it to 53).
You pay 7 cents/Kwh... 0.07 * 53 = $3.71.

Your net income for the 1st of januari 2020 would have been $7.5 - $3.71 = $3.79.
That's about 20 cents more than you calculated... Not much, but still significant, especially when you're doing this calculation for 818 days (818 * 0.2 = >$160).

What i also mis is the resell value of the hardware... I'd personally rather sell off my ASIC than turn it off for many months on end...

Sorry to point this out, but "beginners & help" (the subforum you posted on) is a subforum dedicated to beginners & help questions about bitcoin.

What you're asking is something that belongs in the marketplace subforum (i suppose, not that i follow said subforum that often).
By moving your post to the correct subforum, you have a better chance of finding somebody that's willing to sell you these goods in return for crypto (unless selling these goods is illegal, i'm not really up to date with the forum rules about what can be sold and what is prohibited since i hardly ever participate in the trade of goods on this forum)

I did not redo your calculations so i cannot comment to these exact numbers (you didn't post your exact calculations, so there's no way to verify), but the general idear behind your post might be more or less correct, eventough those 0.041 BTC sound very low to me. In 2018, was this ASIC the price/quality best asic around, or were you looking for the cheapest device? Cause, normally, @7 cents/Kwh, i always believed you should have recuperated your investment if you picked the right asic from the right vendor at the right time and you had an average amount of luck. But once again: it's not impossible that your numbers are correct... You just posted the end result of your calculation, but not the steps and reasoning in between.

I've read, and discussed with, several people claiming it's a good idea to keep mining at a loss because bitcoin's value generally rises over the years... My opinion is that you are correct: you should turn off your equipment if mining at a loss... There is no good reason behind mining at a loss to begin with... Just turn off your equipment and buy BTC from an exchange with the money you would have spent on electricity for as long as it takes untill mining becomes profitable again. You'll end up with more BTC in your wallet this way than if you'd had continued mining.

And that's exactly the answer to your last point: yup, you would be in the profit $600+, but if you'd invested the money for buying your ASIC and the money you'd invested into electricity into buying BTC directly, what would the end result have been?

100% in agreement with Timelord2067... I was thinking about a slightly different defenition that boils down to exactly the same result:
"If you didn't create the wallet.dat yourself, or didn't receive it from the verified creator,  it's either fake or immoral to own"

Sure, if you find a campaign that allows brand new users... There is no forum rule that prohibits newbies from posting, everything else is between you and the bounty manager.

Personally, i wouldn't join campaigns that pay in worthless tokens or campaigns that are managed by people without a long history and positive trust, odds are you spend a lot of time posting utter crap (like those bounty reports) in exchange for either nothing or worthless tokens...
But that's up to you...

I quickly glanced over the thread you linked to... And what pops up in my mind is: why do you care?

The odds of these funds being spent are very, very, very close to 0 because the person losing the 8999 BTC wasn't scammed, or victim of a virus, or phishing... It seems to be pretty obvious it was just bad luck, 8999 BTC ended up funding a change address that was generated by his wallet, but whose private key wasn't included in his backup (and his disk was erased), so those funds are gone.

If these funds would ever move, i would probably conclude the OP was lying all along, maybe as a form of begging... Eventough the odds of this happening seem to be very close to 0.

But if they'd ever move, how would the community react: probably by shrugging our shoulders and moving on? Just some dude who either found a way to recover his wallet.dat, or was lying all along when he posted his problem.

On the install document, they refer to this video: https://youtu.be/8q65eqpf4gE
I've quickly skipped trough it, and it seems to show you all the steps you have to take (including installing python). And the guy making this video seems to have used windows aswell

You might feel overwhelmed, but to be honest, the task of installing a tool like this probably isn't as big as you might feel it is...

Good luck!

I don't think i've actually brainstormed about this question before...

In theory, the chain with the most work would win... But, in your hypothetical case, we're brainstorming about the network being split in 2 (allmost) equal parts for an extended period of time and the consequences thereof...
We do have to take into account that a lot of transactions that ended up in blocks in the shortest chain are, in fact, valid... If they were rebroadcasted after the longest chain (the one with the most work) won, they would also find a spot in a block in the winning chain aswell (since they were spending pre-split unspent outputs, and they were 100% valid since they found a spot in the losing chain aswell)... This is, offcourse, not true for coinbase transactions in the losing chain, for transactions spending the same pre-split unspent outputs in both chains, and transactions building on these 2 "cases".

Offcourse, a complete and utter split of the complete network for an extended period of time seems unlikely to me, the network is connected over land, under the sea, trough sattelites... I think it's unlikely (but not impossible) to see a complete split for more than a couple of hours... Even if all underwater cables between the american continent and the rest of the world were cut on the side, there'd still be underwater cables on the other side of the continent (aswell as sattelites).

Well...
A signature campaign is a deal between you (the campaign participant) and the company you're promoting (usually represented by the campaign manager). There are some forum rules on how to behave in a civil way, but there aren't any rules that govern things like whether or not alt accounts are permitted or whether or not you can join 2 campaigns at the same time.

This means those rules are basically between the participant and the company... The company proposes a set of rules, and participants usually agree to the rules set by the company in order to be able to work for them.
It's perfectly possible (eventough i've never seen this) that a company allows an advertisement for a different company next to their advertisement in your signature area (eventough this will mess up the advertisement's design).
It's perfectly possible (eventough it's rare) that a company doesn't care if you join with alt accounts...

The bottom line is: there are forum rules you cannot break unless you want to get banned, and there are rules set by company's that run signature or bounty campaigns... As long as the signature/bounty rules don't contradict forum rules, everything should be ok

You probably won't like what i'm going to say, but please remember i'm trying to give you some pointers:
The post you've made is part of your "business", it's aimed at finding new clients...

This being said, English isn't my native language and i'm dyslectic, but even I can spot several grammatical errors in your post... I'm not saying i would be able to do a better job, but i'm not searching for a content writer gig... If i were, i'd make sure there were no errors in my post whatsoever...

Imagine searching someone to paint your house, but when you look up their social profile you see pictures from his house showing the ugliest paintjob you've ever seen... would you hire him?

Imagine searching for a tattoo artist, and when you meet one applicant you see his arms are filled with the worst looking tattoos you've ever seen (on a technical level, not the artwork), would you let him put tattoos on your body?

Imagine looking for somebody to maintain your car, but when you have a meetup with the mechanic, you immediately spot several serious flaws in this dude's car, would you hire him?

Here are my remarks, do notice i'm NOT an English speaker, i'm dyslectic and i'm NOT trying to find a job as a technical writer!!!

I came across a hardware wallet implementation on an arduino quite a long time ago... I didn't star the github repo i'm afraid.

A little google query turned up this one: https://github.com/arduino-bitcoin/simple_hardware_wallet but i'm not all that sure this is the one i saw in the past...
The problem with this project in particular is that the private key is stored on the sd card in an unencrypted form, making it a "less optimal" hardware wallet... But nothing is stopping you from improving it

There's just one extra remark i'd like to give: it might not always be a wise idear to start exporting/importing private keys (or seeds) between wallets.

I've never used trust wallet, but i'm willing to make an educated guess that the wallet file from trust wallet is encrypted... This means that if your environment is compromised, the hacker probably can't access your master private key anyways.

When you export your private key, said key is stored in your memory in an unencrypted way... And when you have a private key in 2 wallets, the attack vectors are twice as big...

This being said, i do have an important question: in the past i've seen people posting mixer walk-troughs were accused of being affiliated with the best mixer in their review (or, even worse, they sometimes are accused of being the owner of one of the mixers they list). Do you have any link to any of the mixers you review in your article?
