A transaction is confirmed once it has been included into a block.
Each subsequent block adds 1 confirmation to that transaction. A bitcoin transaction is considered to be completely irreversible after 6 confirmations.
If you are dealing with lots of money, wait for 6 confirmations. For standard transactions or transactions with a lower amount (less than a few thousands), 1-3 confirmations are absolutely fine.

Regarding your second question.. the target (and therefore the difficulty) is chosen so that on average(!) there is a block each 10 minutes.
It is very well possible that we have 3 blocks within 10 minutes, or 2 blocks withon 60 minutes. After all it is pretty random, but the average will be ~10 minutes.

I hope only a few people got burnt there.
There literally wasn't a single good reason to use that exchange over a well known and reputable one.

I wouldn't expect a relatively new exchange with less budget than the big player in this market to be even closely as secure as them.

Not using new exchange or exchanges which are known to be less secure, already reduces the risk of being a victim of such an incident.

Unfortunately there is no way for you to get your coins back.
The system would be broken if it would be possible to simply bruteforce a seed storing BTC.

Since you already used your SSD and the chances of recovery are indeed extremely low, you are unfortunately out of luck.
Data recovery would be the only option if you are sure that you don't have a backup of your mnemonic code somwhere.

That's actually an interesting question.

I don't know any case where someone asked for that.
There is nothing to be found on the website of trustedcoin (the co-signing company).

I guess the only way to transfer the credits (if possible at all), would be by contacting them directly: https://trustedcoin.com/#/contact-us

Das stimmt. Das ist natürlich was, was man immer im Gedächtnis haben sollte.
Durch KYC wissen die ja auch ganz genau wer du bist und wo du wohnst. Mit Privatsphäre ist da nicht mehr viel.
Aber das sind ja auch die Vorgaben für alle Banken etc.. Da kann man nicht viel machen.

Wer wert auf seine Privatsphäre legt und keine unnötigen Verbindungen herstellen möchte, immer schön BTC mixen 

I'm with ETFbitcoin here.
If you want to transfer funds from one wallet to another, you simply need to create a transaction.

I am not sure what you are trying to achieve. Moving funds? Just create a transaction.
Anything else? Like "moving" private keys? Or what exactly?

You should read the OP more carefully.
It is not about bruteforcing private keys, but about bruteforcing the password of a wallet.dat file.

Those two things are completely different. Bruteforcing a private key is not feasible, yes indeed. But cracking a password can be possible. It purely depends on the strength of the password.




Brain wallets are cracked because people are dumb and the entropy is low enough to be bruteforced.
There already have been quite some brain wallets emptied which were derived from the rockyou.txt password list (most used passwords).

Bruteforcing private keys is (and won't be) feasible.

My guess would be that they simply took that part out of the code.
The malicious version creates and broadcasts a transaction as soon as possible. It wouldn't work with a hardware wallet, so i guess they simply ignored that and removed that part.

Just a guess tho.

There are people around here who lend out testnet coins for a small collateral.

But what do you need that many coins for?
You should be able to do all of your testing with less than 0.1 tBTC? Why do you need such a large amount?

What kind of software are you talking about? The firmware on the HW device or the software running on the PC?
I doubt they would allow other software to be patched onto the trezor.

And regarding the software on the PC, i doubt this would be feasible too. You'd need to evaluate what exactly is a "good" software. And you'd need to update the signatures quite frequently (i.e. after each update).
And for that, you'd need the user to actually start up the original trezor software again which would then transmit the new list (integrity-protected) to the HW device.
Sending a signature back from the HW device to the software isn't really necessary, since the computer can be compromised and a malicious version would not care about the signature and/or it could be spoofed.

Never do anything without a backup.
Please read the quote again:


Your wallet (storage of your keys) can still be backed up, since it basically is a file on your computer.
Just copy the wallet.dat file in the above path to a save location (preferably not only on your pc).

I guess the easiest option is option #2 mentioned by mocacinno.

Based on your question, i assume you are using windows.
Right click on the shortcut -> properties -> add " -reindex" (with a leading space, without the quotes) in the "target" field at the end.

You want it to look like:

Obviously the path itself will be different on your system.

You always have to be careful on what you are downloading and/or executing.
It's not like there is no malware for linux. Malware for linux (or mac) does exist. It is just that the majority of malware simply is written for windows since it has the largest user base.
Therefore, if you know what you are doing, indeed an AV is not needed. But common sense (i.e. not downloading and executing random stuff) is always required, regardless of the OS.

OP introduced a crypto-based lorem ipsum. A lorem ipsum is a placeholder text.

If you would write your own text, what would be the use for a placeholder text then? 
Generally, that's used to check the layout/design of for example a webpage before actually filling it with content.

I guess that approach is being made decentralized.
But encryption using private keys is retarded.

"Encryption" using private keys -> verifying with the public key = digital signatures
Encryption using public keys -> decryption using private keys -> actual public key crypto usage

It is very well possible to encrypt a message with the recipients public key. And only this recipient will be able to decrypt the message.
But encrypting (symmetrically?) a message using the private key is indeed a dumb idea.

Not really, no.
Emotet is written solely for windows. Neither linux nor mac user are affected by it.

And if i am not mistaken, it relies on the eternal blue vulnerability to spread itself.
So, having an up-to-date system already ensures that your system won't get infected without manually doing so (e.g. by downloading and executing untrusted software).
Regularly updating your system and not clicking on every link / downloading every software already is enough to not get infected with malware most of the time.

It is not like every wallet sold is a legit wallet with a forgot password.
Those wallet files are being faked to display a large sum of BTC.

There simply is no password which will give the user access to those shown BTC.

Of course that's now only referring to the wallet sales on this (or other) forums and not on the rare cases where someone actually indeed lost the password and now sells this wallet file.
Unfortunately a lot of people are getting scammed by this.

I'd highly recommend you both to actually read about quantum computers and what they can achieve.
They are not magic machines.

There are quantum algorithms which do decrease the search space for specific mathematical problems, yes.
But they can not just easily crack and bruteforce everything.

This is dangerous sciolism being spread by unaware people.

Since you have access to the hardware, you actually have also access to the bios.

Resetting the bios will clear the password. There are jumpers on the motherboard to exactly do that.
The exact procedure is depending on the model used.

While i guess that you won't do that (and you probably shouldn't), you definitely can 

Connecting to a bad server doesn't harm you. Installing malware without verify the signature does.

If you have a lot of BTC, you actually should either get a hardware wallet, or use a cold storage setup (as described by o_e_l_e_o).
I'd not recommend to use a desktop wallet to store an amount of BTC you definitely do not want to lose.

If you are transacting very often, get a hardware wallet (~70$). If not, a cold storage setup would be even better.

That's a completely worthless article not worth being mentioned.

Those "Hackers" do not hack anything. They are trying to bruteforce a password.
Thats's nothing new, wallets are being traded here all the time.

Further, no one can be sure that this wallet indeed holds the private keys. I am pretty sure that a wallet can be manipulated in such a way.
We can observe this all the time here, where people "lost their password", but in reality just bought a wallet file.


It is disappointing to see what kind of articles get published.
