It seems to have been a temporarry problem, it's back up now

Since people were saying this is not some kind of experiment, and a lot of nonsense was being posted, even claimed they could break even... I decided to digg a little bit deeper.

I have to admit, i was a bit lazy, so i used this post to get the formula daily revenue:
https://bitcointalk.org/index.php?topic=726962.msg8221939#msg8221939


Offcourse, the block reward dropped to 12.5, so we have to exchange 25 to 12.5 in the above formula

So, the revenue = the hashrate (H/s) * 491512500  / 281474976710656 / Difficulty * 144
If we use this formula to calculate the dayly revenue of an antminer S9:
1.4e+13 * 491512500 / 281474976710656 / 1103400932964* 144 = 0.00319045009

coinwarz is a pretty reliable mining calculator used by lot of people, at this moment, it reports a dayly revenue of 0.00319050. I think this proves the formula is relatively correct.

abhinav_thakur01 reported a hashrate of 1-2 H/s

Plug 2 H/s into the above formula:
2 * 491512500 / 281474976710656 / 1103400932964* 144 = 4.56 e-16 = 0.0000000000000005 BTC/day = 0.00000005 satoshi's/day = you'll need to mine over 50.000 years to mine a single satoshi at a speed of 2 hashes per second.

If we re-read TheQuin's statement, and combine it with abhinav_thakur01 speed report, then plug everything into coinwarz with a 10 cent/kwu power cost

link
We see that the net loss of such a mining operation would be ~$7/year, simply because (luckily) the power draw was only 8.5 watt. The net loss is calculated this way: the income of your mining is 0 (nill, nothing, zip) minus the power costs (~$7/year) gives a net loss of ~$7/year.

A re-state my previous theories about freebitco.in browser mining... i'm pretty sure one of these theories (or a combination of these theories) is the correct one:

• OR they're not bitcoin mining like they claim, but mine a coin that is still cpu-only minable, but still pay you in BTC
• OR they're performing some other task in the background... Don't know which one tough
• OR they just use the browser mining as a trick to keep you on their page... They subsidise your account for staying with them 24/7, watching adds

And as a final wacko theory i wanted to add this link: http://www.csl.mete.metu.edu.tr/Electromigration/emig.htm
It's an interesting read for everybody that claims there is no harm at running your cpu at 100% for long times (or overclocking your cpu).
I know it's not completely on-topic,  but it's still interesting nonetheless

I see... The hacker stole your fubds, moved it to a temp addres, then moved to the addres it's currently on... Never mind my warning then...

I'm very sorry for you... 29 btc is a lot of money to lose.
Just in case you'te somebody who has even more btc: a trezor hw wallet costs 100 bucks and should protect you from hackers and virusses

Nope... The only option you got is keep on tracking and hoping that at one point, the funds can be tied to an addres whose owner is known. At this point you can report said owner to the police....
But don't get your hopes up, chances that this will happen are very slim. Usually hackers will launder the money very fast.

Wait: if the funds are now @ that address, this means that this is your address: https://blockchain.info/nl/address/113cesQ3HJxEkzZ9iRXg3jMoFgKMXhiCgA

Why are you depositing funds to a hacked/compromised wallet!!!

This is a ver bad idear

If it's really BTC mining, i wouldn't bother.... Chance of your pc overheating would be a lot bigger than chance of making enough BTC to withdraw, ever.

I found this old thread:
https://bitcointalk.org/index.php?topic=9042.msg130903#msg130903

I can't quote the post, since the thread is locked, but SoreGums gave following hashrates:


plugging those numbers into coinwarz:

0 sat/year...

So, they're either not really mining in the background, and just use this miner as an excuse to make you stay on their page and watch their ads, or they're doing something completely different using your computer and pay you in BTC (like mining monero, or they're doing something useless that will break your pc without any profit.

Sort off... If you look up the transaction on a block explorer like blockchain.info, you should be able to follow where your funds are going to.
However, if the thieve uses a mixer, deposits the funds to the hotwallet of a casino, exchanges your BTC for a more anonymous crypto currency, the trail will end.

You can follow the trail as long as possible, and look up the addresses in the trail on https://www.walletexplorer.com, bitcointalk.org and/or google you *might* find more information about the thief... Chances are slim you'll find the culprit tough, they're usually smart enough to avoid any traces.

If you open that page, you'll see that at the time of writing, the mempool contains
~10k unconfirmed transactions with a fee between 0 and 20 sat/byte
~8k unconfirmed transactions with a fee between 21 and 40 sat/byte
~1k unconfirmed transactions with a fee between 41 and 60 sat/byte
...

Since a block contains ~2000 transactions, your fee should be high enough to put you in the top 2000 transactions, that way you have a decent chance of getting your tx into the next block.

The graph also shows you the estimated waiting time for a 95% chance of getting into the next x blocks with any given transaction fee. For example, at the time of writing, adding a 20 sat/byte fee will give you a 95% chance of getting your transaction confirmed within 840 minutes.

Under the graph, there is a text that currently reads:

So, basically, if you add a fee of 180 sat/byte, you should be fine.

I'm defenately not disagreeing with you, however, bitmixer has stated they closed their mixer because they stopped believing every bitcoin user has the right to privacy (https://bitcointalk.org/index.php?topic=2042470.0). They might have had an alterior motive (they might have been forced to close shop, they might have been blackmailed,...), but they didn't give any extra motivation.
It's not because they had a change of heart, everybody should have a change of heart.

Personally, i'm a strong believer in privacy, and as long as mixing coins is not considered illegal in my country, i'll keep on stating that there is nothing wrong with using a mixer. I'll also stand behind any honest and reliable organisation that opens a mixing service.


you don't need to be a criminal to mix your coins, your BTC doesn't have to originate from criminal deeds for you to want to hide how much BTC you own.

For example: you might have been doxxed in the past, so everybody and their mother know who you are, where you live, where your kids go to school and which address you usually use to receive payments. Wouldn't it be normal you wanted to break any link between your public payment address and your private address? If you didn't break the link between those two addresses, everybody would know exactly how much BTC you were holding, which would give them a great incentive to break into your house at night and take your family hostage untill you gave up your BTC... Wanting privacy != illegal.

Here you go, please note that i couldn't verify any signature since it was not clear to me what your message text might have been.

3 tx/s in memory. => No, just look at the post above your post... I clearly calculated that pre-segwit, the network could handle ~4.5 tx/second. Post-segwit that number should increase.

every block size is 1MB now. => No (look at the screencaps i posted)

BCC has a bigger block size which is 8mb. => Yes... The block size can be UP TO 8Mb

Block smaller than 1 Mb:


Block bigger than 1 Mb:

Historically, a bitcoin block had a maximum size of 1 Mb, an average transaction has a size of 226 bytes...
So, historically, on average, the network could handle ~4,5 transactions per seconds...

Now, segwit has come into the picture... https://medium.com/@jimmysong/understanding-segwit-block-size-fd901b87c9d4
Basically, the witness data is not sent to legacy nodes, making the transactions smaller and allowing more transactions to fit into a single block.

Please explain to me how an expert electrician can make your electric bills less. AFAIK, a 1400 Watt power draw remains a 1400 Watt power draw, no matter what your electrician does. The only ways to make your electric bill less is either switching to a cheaper plan, underclocking your ASIC so it uses less power, using less ASIC's or upgrading your mining farm so you use more efficient ASIC's. Or am i missing something here?

Or are you talking about tapping electricity from the net ilegally? In which case i'd say that's very bad advice.

I looked up how many watts one could produce by running on a bicycle and ended up with articles like this one: http://michaelbluejay.com/electricity/bicyclepower.html

The writer estimates one can produce ~100 Watts, not substracting any loss due to conversion or any hardware/repair costs.

An antminer S9 is currently the "best" ASIC on the market (the best J/Gh rate on the market).
It has a power draw of 1375W + 7% and a hashrate of 14 Th.

Basically, you'd need 14 of those bikes running 24/7 to power 1 antminer S9.

At current diff, block reward and BTC price, you'd make $12.91 a day (since your power would be "free"
https://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=14000&p=0&pc=0.00&pf=1&d=1103400932964.29000000&r=12.50000000&er=4087.21110000&hc=0.00

In order to run 14 bikes 24/7, i'd estimate you'd need at least 70-80 people employed fulltime
In my country you'll work 8 hours a day, 5 days a week, 52 weeks, 25 hollidays + 5 religious hollidays, 5 days of being ill (estimated) = 1800 hours/year
you need 14 bikes * 365 days * 24 hours = 122640 hours
122640/1800 = 68,1 fulltime employees (if everything goes right, and this only covers the bikes, not the maintenance, long illnesses, accidents, paperwork... So i'm going to assume you need at least 80 fulltime employees to cover all bases)

So, in my country, the costs would be:
80 employees * €35.000 + 1 antminer S9 (€1100) + 18 bikes (14 bikes + 4 spare bikes... I estimate them at €1000/piece including the convertor) = close to 3 million euro's/year

The profits would be €11*365 =~ €4000/year

The negative profit of the setup would be close to a net loss of about 3 million a year...

Since you seem to keep +3BTC, in hindsight, you should have invested 100 bucks for a hardware wallet... Or at least keep the bulk of your funds on a paper wallet, generated on a clean, airgapped PC.

If you were asking what you could have done after you realised you downloaded malware? If the malware created and broadcasted a transaction that emptied your wallet, you *could* have tried to double spend one or more of the unspent outputs used in the stealing transaction... But that's about it. Creating such a transaction is rather technical, and hard to do if you have little experience in manually creating transactions, it is also a longshot without any guarantee of recovering your funds whatsoever.

Once a transaction is confirmed, there is no way of recovering your funds (so, on average you only have ~5 minutes to react before your money is gone forever).

Sorry...

What???
So, you suggest to pay a fixed fee of 0.11 to 0.39 BTC? At current preev rate, that would be a fee between $434 and $1540. I might not be living in THE richest country in the world, but that fee seems a tid bit high for me... Also the fact you're suggesting a fixed fee makes me uneasy. A fee is calculated based on the size (not the value) of the transaction. A transaction with a lot of inputs/outputs needs a higher fee than a transaction with only 1 input and one output. (important to note is that i'm talking about the NUMBER of inputs/outputs, not about the VALUE of the inputs/outputs)

@OP: bitfort gave the best answer, use https://bitcoinfees.21.co/

A technical way to calculate your fees:

Alternative, you can use my fee estimator: http://www.mocacinno.com/page/feeestimate

A GOOD wallet, and the proper knowledge on how to use a GOOD wallet will usually result in an appropriate fee being added without having to calculate sizes. A good wallet should do this task for you.
Stay away from online wallets like blockchain.info. In the past, they've done a horrible job in calculating appropriate fees. I don't know if they fixed this, but they used to be utterly bad at this. Also, when using an online wallet, you're not the only one in controll of your private keys, so you're not the only one in controll of your BTC... Beware!

i wanted to give you some advice on how to change your post in order to have a tiny chance of finding the correct seller:
1) change this post's title... "i am ready for buy" says nothing about your intentions, what are the chances somebody owning this book will open this thread (hint: close to 0).
If you change the title to "[WTB] ebook about phreaking and isp hacking"

2) let somebody proofread and correct at least part of your grammar mistakes... I'm not a native speaker, but i think that if you change your text to the following, you might have a better shot:

3) you're a brand new member, it would be wise if you used a trusted forum escrow. Using an escrow would be safer for you, and any potential seller, thus enhancing your chances of finding such an ebook.

Good luck!

I don't see why software developed by the dev's of bitcoin core would in any way be different than most linux distro's out there... Except the fact that linux dev's have been working on their OS for many years, while bitcoin dev's might not have a lot of experience in writing OS's. It's all open source, it can all be compiled by you (if you really want to).

If you mean, cellphones running straight from the blockchain, i must say i don't see any technical way of booting a device from a decentralised ledger... That would be impractical (to say the least), maybe even impossible.

last but not least, a common misconception: Bitcoin != Anonymous
All bitcoin transactions are recorded on a public ledger which can be downloaded, parsed, verified, analysed, tracked,... by anyone that wants to do this. All inputs and outputs of every transaction are known...
If you want anonimity while using BTC, you need to use external anonimity services like mixers in order to achieve some anonimity, so don't confuse Tor and VPN with the blockchain.

no, IIRC the masternode concept was created by the developers of DASH. Bitcoin, for example, does not have masternodes.

For your specific questions about masternodes, it might be best to read dash's website: https://www.dash.org/masternodes2/ or to ask your question in the altcoin subforum.

I wouldn't have requested a screenshot... A screenshot from their side proofs nothing.
If you can proof that you've used the correct deposit address, and you can proof that the transaction you posted earlyer was created by you and you can proof that the sent value was equal to or bigger than the requested value, they don't have any reason not to send you your goods/services.

The fact they claim they received nothing is 100% their own problem. They gave you a deposit address and you can proof you funded this address. Period...
It doesn't matter if their wallet is not sync'ed, their SPV wallet is connected to a wrong server, they have a virus on their pc that made them send the wrong address,... It's 100% their problem and not yours.

The last 2 things you can do is open a scam accusation on this forum, or go to your local police office and make a formal complaint. If you open a scam accusation and post sufficient proof (screenshots, txid's, signed messages), you might be able to put some pressure on their organisation to solve your case, or otherwise they might risk losing business...

I don't own a mac, but if a mac allows you to remove one of the two versions without deleting the wallets themselfs, it should be no problem... You can always backup the wallets anyways, or restore them afterwards (in case the uninstaller does indeed delete your wallet).
