Is bitcoin paper wallet safe to dump bitcoins ?

[BlackMachine]

As long as they are created from secure place & you delete any history afterward, it should be safe enough
Multisignature addresses & hardware wallet could improve the security

multi sig address means that the wallet is created such that m-of-x signatures required to spend the coins. depending on how you spend the coins, for example, signing all keys on the same computer. This can expose you to malware threats. Hardware wallets won't help if they are poorly designed and get exposed to exploit.

[twister]

The bitcoin wiki is quite informative on this subject, just good read, the basic idea behind creating a paper wallet offline is that if it stays offline it cannot be stolen through hack or malwares.

Here are the link which might help you get more clear understanding on how cold storage and paper wallets work.

Not sure what crappy advice you're getting here bro but please visit the following website -
https://www.bitaddress.org
Disconnect from the internet when the page is loaded up, wiggle your mouse around randomly, type a few random characters into the text box, you should then generate a bitcoin paper wallet, you will have a public & private key.
Can you see BIP38 Encryption?
Type a passphrase in, remember this, you will need it to get your coins back onto an online/hardware wallet if/when you decide to in the future.
Print a couple of copies, you now have a bitcoin paper wallet & can send your coins to the public address safely.

I find this suggestion useful to create paper wallet
 My computer is 100 % protected and clean bcoz of my antivirus.

I don't think any way is 100% safe but the above is what I have always done & I've had no problems.
People come on here & tell scare stories but if you just browse the internet for regular stuff you're not going to pick up Mi5 / James Bond style / secret agent style hackers who are clever enough to break BIP38 encryption.
I like being safe & secure but there are limits when paranoia can be excessive & a bit weird.
You can type your public addresses into any block explorer & always check your paper wallet balances at any time.

I still don't understand how it's possible to create a wallet while disconnected from the internet. I've seen those tutorials on bitaddress.org where they get the html code and run it offline to create the address. How does the blockchain know those address are valid and exist if they were created online? I cant get my head around that.

I am looking to dump my bitcoins to safe place to btc paper wallet. I want to know that is this safe to use paper wallet for storing my btc fund.

Post your valuable suggestions.

to split your funds is always a wise decision.

you can also use a hardware wallet for the 2. or 3. chunk.

uhh... it should not be any different than running bitcoin core without internet and creating an address then dumping the private key associated via console commands

They will be always valid if the client generates a key that has a corresponding public and private key and the format fits the protocol requirements. Its existence will only be known when the client broadcast a transaction to and from the network. Address collision will also not be an issue here since 2^160 keys can be generated. They can be exploited if you have weak RNGs however.

I lolled  

"My wallet is safe because I gave it to some guy I met on the street, and he said it looked good he would hold onto it for me".

[BitRod]

i prefer using coinkite with multi sig. They dont have my keys. Safest other than paper wallet.

If the harddrive you created your wallets on ever touches the internet again YOU ARE DOING IT WRONG.. The harddrive should be destroyed after creating the wallet..

So, making paper wallet and using it to store your bitcoins is not much easy and secure. You have to aware Everytime using your paper wallet or making transaction with it.

[bornil267645]

From what I understand, as long as the wallet remains off-line it will be safe. But if it comes into contact with slightest of network, then it has every possibility of being hacked.

Suggest me the legit paper wallet generator. I will generate my paper wallet from that site.

Not completely accurate.

If it is encrypted the saftey concern is someone finding out your pass phrase.  Assume your harddrive is constantly being viewed by others and if it is taken offline and back online all the information has been sent on.

With this assumption the computer used to create the wallet must be offline and should never be online again. (it will cost you $15 for a cheap harddrive.. $15.. use ubuntu.. it's not expensive, the first go involves some learing but after that it is cake walk).

So you create the wallet on the offline computer, burn the wallet ot a cd.  Shut off the compter, remove the harddrive, decimate the harddrive.

Copy that file onto your main computer, and then copy it everywhere.

If someone gets your wallet you're fine unless you encrypted it with 1234566 or

passwordpasswordpassword..

Don't use dumb pass phrases.. 20+ chars, no real words, special chars  add.. ╜ for example .

Nah. Unless you're using windows 2000. The wallet should be kept offline (If possible). If not, contact with internet is fine as long as the system is clean of malware since some malware can transmit info once it comes online.

Has anybody here ever had any trouble with a paper wallet? I mean I know high tech malware exists but has anybody ever had an issue?
Some people are overly paranoid, I mean what kind of sites are people visiting to be worrying about back door malware, what kind of files are these people downloading?
I just go online for basic stuff, I'm not a techie, I don't visit places where highly skilled hackers will be out to play.
I think if you create your paper wallets offline & clear your history you should be ok, run regular virus scans.
Don't go on Tor or visit any nerd internet forums/sites.
You should be safe.

It is my wealth bro..  why people just throw their wealth into something and give zero fucks about security blows my mind.

Should That proves my point.


You are on these forums..... your e-mail is known by parties that would look into taking your bitcoins.


Why not be paranoid..  Really though.

Have I had an issue, no, have I head of them, yes.  Perhaps because I am so paranoid I've had no issues .

Why are you using bitcoin if you have no desire to use it's security features properly?

1. Probably not. Unless the printing is bad.
2. Every single site. There has been cases of sites legit being hacked and stuff inserted. *erhm*Bitcointalk.org*erhm*
3. Those sites still have the potential. There isn't a clear line of websites where the skilled hacker will not go to.
4. Some computers store cache in their memory and printer does this as well. You have to thoroughly clean it. Virus scans can't and will never protect you from every single kind of viruses.
5.Tor can be malicious due to MITM attacks. But nerd internet forums=bitcointalk.org. Again, it doesn't matter what kind of website it is.

I use bitaddress.org.

In all of these considerations one needs to consider the "cost of attack".  Unless you are putting thousands upon thousands of coins away, it is unlikely you will be the target of van eck phreaking and state of the art magnetic forensics anytime soon. 

Also note that it is possible and recommended (for large amounts) for spending from cold storage to sign your transactions offline, then move the signed transaction to the online computer for broadcasting to the network.

Why are you using bitcoin if you have no desire to use it's security features properly?

I have a decent stash of bitcoin, my protocol has always been to split it up into paper wallets containing between 2 & 5 bitcoin.
I never do an exact number like 2.000, I like to make it random to confuse any potential hacker.
Now, I am interested in security, I do everything in my power, some of my paper wallets are over 18 months old.
I regularly sit down & type all the public keys into different block explorers & the balances are all what they should be.
I've never had a problem with my method(s).
I think it depends what kind of person you are, what sites you visit, what files you download that determines your likelihood of being hacked. Obviously you could be unlucky too but online shopping & visiting standard mainstream sites you are likely to be safe.
People who stream films, sport etc, download files from techie/nerd sites are likely to pick something up.

If BTC jumps up to +$100k.. how safe would you feel about your BTC?
