Here we go again... The conspiracy theories.  Smiley
Why the hell did you post this?  Isn't it enough that he and his army of sock puppets post the same shit day after day?

Or, are you just yet another one of his socks?

If you are not one of his puppets prove it by deleting your OP.

This is why I am moving most of my BTC to either cold storage or my Trezor.  Trezor is not affected by key logging.

2023  Bitcoin / Bitcoin Technical Support / Re: 0.2 FEE!!!! ? am i missing something? on: August 08, 2014, 08:12:30 PM
did i just lose a .2btc transaction because the fee was set at .2btc?

Aww man, I'm so sorry reading that!! Things can be confusing in advanced settings, yeah... Better just stick to the regular send-feature! I once almost screwed up with those long Bitcoin addresses. Mixed up a few numbers or letters. It was already pretty late and I was out partying!
FYI:  Bitcoin addresses have a built in "checksum" so if you type any digit incorrectly it will not be accepted as a valid Bitcoin address.  You would have to change and swap the letters and digits in a very non trivial way in order to accidently create another valid address - for all practical purposes it is impossible.  If you do manage to be lucky enough to mistype an address in such a way as to create a different valid address then you are so lucky you should be playing the lotto every chance you get.

I use lastpass and change my passwords regularly to new long randomly generated passwords.  I don't have to remember them lastpass does that for me.  So far, so good.

This is less about brute forcing private keys and more about hijacking a wallet application. In 15 minutes I could write a macro that can learn and replicate mouse clicks and keyboard entries in relation to an established GUI design. Now I have all I need in order to hijack a wallet application and make a quick and highly automated payment. Why should I be able to write a macro/keylogger with the piece of mind that if it worked on my test rig it might work on the PCs of victims? We are concerned with securing the data yet we make no attempt to safeguard against something that could simply take control and drive the application in the wrong way? That was the point.
Ah, thanks for clearing that up.  You state "replicate mouse clicks and keyboard entries", so is it safe to say your concern generically is keylogging?

I have followed BCX's "career" here on bitcointalk over the years and I also believe he would make an excellent mod for the alt coin section.
2027  Bitcoin / Development & Technical Discussion / Re: Wallet designs - dangerous path emerging on: August 08, 2014, 06:36:06 PM
Could you be a bit more specific about your concerns?  Here is an example of what I think you may be talking about:  everyone using the bitcoin-qt wallet stores their bitcoins, actually their private keys, in the file named "wallet.dat".  So a thief, upon finding a computer, only needs to scan for the file "wallet.dat" in order to find the private key file.

What you are suggesting is that the average user should be able to rename the file to something like "bitcoins.dat" and this ability of the customers to customize this (and other things) would somehow increase security?

I agree with the previous poster that in this example what we really need to do is to make sure everyone encrypts their wallet.dat file with a strong password and leave the name alone.  Encryption of the file is the correct answer to security, not being able to rename the file.

Forgive me if I did not fully understand your proposal/concern.

^^ Not a miner so I'm not certain about this but I thought all the pools held their miners details for security purposes? Not that this is one but I'm just saying they SHOULD know who's address it is.
They could remain anon and just send it back to his original address - everyone knows his original address from the transaction.  Getting the money back would not prove/disprove it is Bitfury.

If the owner is reading this they might just do that.
2029  Bitcoin / Bitcoin Technical Support / Re: 0.2 FEE!!!! ? am i missing something? on: August 08, 2014, 12:35:07 PM
I think the sad truth here is that Bitfury probably does own that address but does not want to admit to it.  If your fee had landed in a block mined by a well know above-the-boards pool then you would probably already have it back.  You were unlucky in that your fee happened to land in a block mined by someone who wants to remain anon.
2030  Bitcoin / Bitcoin Technical Support / Re: backing up wallet question on: August 08, 2014, 12:26:54 PM
It's not a good idea to do this with a non-deterministic wallet. Each time you send bitcoins, bitcoin-qt generates new private keys to add to the key pool. These are entirely random. Eventually the two wallet copies will diverge and you'll have different private keys in them. It'll be very confusing and you risk loosing bitcoins.

If you want to share a wallet on different computers use either a web wallet or a deterministic one like electrum.
Please listen to this very good advice.

I considered the OP's question to be hypothetical but now, reading it over again, it looks like this is something they might be thinking about actually doing.

Can I run the same wallet on multiple computer at the same time? Anyone know? thanks.
DO NOT DO THIS for the reasons stated above.  It can be done but a) you really have to know what you are doing and b) it cannot be done with the bitcoin-qt wallet.
2031  Bitcoin / Bitcoin Technical Support / Re: backing up wallet question on: August 08, 2014, 12:00:40 PM
what wallet you use ? check your email . downnload backup and save in flashdisk or save place who never can steal or copy your private key .
"if you have a lot BTC"
I see you are new here so I will be nice.  The standard way to make a post is:

1) Read the question
2) Answer the question if you know the answer

What you did was:

1) Skip the question
2) Write some random stuff unrelated to the question

Watch this:

Hello, If i back up my wallet on bitcoin qt and I have other computer with bitcoin qt downloaded too. If I paste my wallet.dat file on my other computer and I do some transactions, will my balance also updates on the first computer too? Can I run the same wallet on multiple computer at the same time? Anyone know? thanks.
Balances are not kept in your wallet.dat.  The wallet balance is actually caclulated from the blockchain.  What is actually in your wallet.dat is just your private keys.  So, to answer your question, if you have multiple wallets that have the same set of private keys (the same wallet.dat file) then the balances in all of those wallets will be the same and will be kept in sync as each wallet calculates the balance from the set of private keys held in the wallet.dat file.

If you have any more questions just let me know.

Is this going to happen soon? Im sure if this is a standard feature of the bitcoin core other developments will follow suit like electrum and mycelium etc.
Some web sites have already started using bits as an option for displaying bitcoin values.

This sounds so much better. I hope bits have as much value as cents in the future.
Not quite.

The idea is that when we use bits for prices the prices will have this familiar format:  1,234.56 bits

The partial part of the bits (the 0.56 part) is in satoshis so in the future bits will be analogous to the "dollars" part and the fractional part, the satoshis, will have the value of "cents". 

People would eventually say something like "That will be one thousand two hundred thirty-four bits and fifty-six satoshis."

interested wallet but when hardware lost ? get tsunami ? my money will loss ?
Obviously, nobody would be excited about this product at all if this was the case.
2035  Bitcoin / Bitcoin Technical Support / Re: 0.2 FEE!!!! ? am i missing something? on: August 08, 2014, 11:34:46 AM
Anyone know what is the biggest fee so far sent to miners?

This may not be the largest fee ever sent but it was $23,638 at the time of the transaction and is $117,712 in today's BTC:

Also, please do not edit my post when quoting me.
Wow, I find it hard to believe that you have 227 posts and nobody has ever edited your post in order to answer part of it, like this.

You are new so I will tell you this is standard operating proceedure around here - nothing to get upset about.  I almost always cut down the post to just the part I am responding to, like this.
2037  Bitcoin / Bitcoin Technical Support / Re: 0.2 FEE!!!! ? am i missing something? on: August 08, 2014, 11:26:07 AM
Blockchain should add a fixed fee according to amount you want to send.
They already do this.
2038  Bitcoin / Bitcoin Technical Support / Re: 0.2 FEE!!!! ? am i missing something? on: August 08, 2014, 05:36:39 AM
if anyone  were to be so kind and help mitigate my loss via crowd sourcing it would be much appreciated.. I know I have helped others when they were few dollars short via btc
A few years ago I lost over 10000 BTC to a scammer.  If anyone would like to send a few hundred my way I would really appreciate it.  If only 100 people each send me 100 BTC it would be made whole.  Thanks!

Edit: that may be asking for too much, how about 1000 people each send me 10 BTC...
2039  Bitcoin / Development & Technical Discussion / Re: Brutforcing a wallet on: August 07, 2014, 10:43:45 PM
I was messing with the program where you put in a passphrase and it will make a bitcoin address. I actually found two that were used. one passphrase was satasi nakamoto and I cant remember the other one but it was an easy on too. Found that kind of interesting..
Generally, creating a private key from a passphrase is a very bad idea.  Private keys should be created from a cryptographically secure random number generator.
2040  Bitcoin / Bitcoin Technical Support / Re: 0.2 FEE!!!! ? am i missing something? on: August 07, 2014, 10:40:59 PM
So what is the recommended transaction fee to input manually to guarantee this does not happen? This is making me scared to make transactions now.
Most wallets will calculate the proper fee for you.  What wallet are you using that you have to enter it manually?
