Topic: Is bitcoin paper wallet safe to dump bitcoins ? (Read 5344 times)

yes it is absolutely safe

The type of Anti-virus you use, does not give you 100% protection against all backdoors or Trojan Horse or key loggers. None of them are 100% safe, even if they say so.

Go to a second hand shop, if you do not have a old computer and buy the cheapest computer you can get. Go to bitaddress.org and save the page as a complete webpage on a flash drive on your primary computer. Then transfer these files to the old cheap computer you bought, and open the file offline. Create as many paper wallets as you might need from that computer, and physically destroy the harddrive, after you print it.

If you will not go onto the internet with that computer ever again, you could still keep it, to print more for your friends and family. I got a old computer and a printer from a friend, that they wanted to throw away. So I paid nothing for it.

It might sound a bit overkill, but if you are going to store say 10 000 Bitcoins in a paper wallet... you will not be bothered to spend say $20 on a old outdated computer for this purpose.

Keep the paper wallets laminated and a copy in another location in a safe place.

Aren't there some alert programs that warn you for every incoming and outcoming transaction to adresses you specifiy? May be much easier than checking it manually.

All four pages here and no mention of Armory. Just install Armory in an offline computer (get a 30.00 junky laptop off Ebay) and the first thing it does is print a paper wallet for you. Print it to PDF or print it to paper and be done. Safe as your mother's arms and easy as pie. Actually, it's easier than pie. Have you ever tried to make a pie? You can't do it in two clicks. You just can't.

Now I need to have some pie. See what you guys did? Ugh.

My computer where I have generated it , it have  Net protecter Anti virus . So, if I access internet on my pc, is there any chances to get my private key get revealed ? I don't have much experience using paper wallet .

Nothing is 100% safe but you've taken precautions. Creating it offline is good practice. You should be fine, maybe laminate the paper wallet & hide it somewhere.

I created my paper wallets offline, every now & again I type the public keys into a block explorer to check the balances & 'all ok' so far.

I have created a offline paper wallet today and deposited some btc in it and save that paper wallet to my pen drive plus take out a print of it.

Will my paper wallet become safe ?

I've used plenty of paper wallets without mishap over time and it's still my preferred method.

I think it is a safe option to have it stored in a paper wallet as it will act as a safe and secure cold storage for you. Be sure to keep it safe locked if you want to stash away some huge number of bitcoins, you could wake up one day after few long years , say 10 to 25 years and realize the price has gone up significantly and cash-out your bitcoins from paper wallet, i have known people who had mined bitcoin in the early days but completely forgot their wallet only to know search their hard drives for wallet to cash-out or use the bitcoins

No pun intended eh?  Your point stands  

It's not the storing offline that is key..

It's the encrypting it offline that is utterly KEY.

The device which you typed in the passphrase should never touch the web ever again.

i new realize there is no safe place if i stored my bitcoin as online by the way that give me the idea for safe my bitcoin and avoid from hacker accident,thank you so much

How is it ? If I use a brand new Pen Drive than Hard disk ? Buying hard disk is not easy for me for now.

I am thinking to save and keep my bitcoins in a safe and secure place.

too much work i guess, isn't just better to use a laptop dedicated to running the client and all the operations with bitcoin?

something like

buy a cheap laptop, do a secure erase(or buy a new ssd and get rid of the one inside it), install only the OS and NOTHING ELSE

run it on a private network and not shared with your other desktop

run the client with your 10k bitcoin coins that are worth millions

no one can put a dent on it, you are safe from online hackers, physical thieves are another story...

I lolled again!  If you are installing "some good antivirus" you have been fooled.  End of story. 

One does not clean a shirt by getting some dirt from anonymous parties and rubbing it in real well.

My method for offline storage on paper:

Creating and loading the wallet -

1) Save to your hard drive the bitaddress.org URL for generating BIP-38 encrypted paper wallets.
2) Create a LINUX LiveCD for booting from a flash drive for a fresh, offline OS.
3) Disconnect computer from the internet, boot into LiveCD, and generate an encrypted paper wallet via the bitaddress.ord URL (running standalone). DON'T LOSE YOUR PASSWORD!
4) Save the wallet off as a PDF and also print multiple copies. Since it's encrypted, you can have a few copies and keep them multiple places and the PDF will also be available if the paper fades or is destroyed.
5) Reboot regular OS and head out to the exchange.
7) Send your bitcoin to the public key of your paper wallet, starting with a small amount and confirming it got there via blockchain.info.

Getting bitcoin back out of the wallet -

1) Using the block chain website or app on an android tablet, scan the encrypted private key of the paper wallet (I could also use the bitaddress.org code offline to decrypt it manually).
2) The app/site will ask for the key you used to BIP-38 encrypt the private key - type in the password used to encrypt it and the wallet's bitcoin will be accessable to send/spend.
3) Sweep the wallet into your blockchain online wallet. (Important since you must spend all coin in a paper wallet at once or risk losing the "change".)
4) Send any bitcoin that you don't want to keep in a hot wallet into a new paper wallet, created in the same way you created the first one. You can create multiple paper wallets at once above, so you can create a bunch at once and just move your change to the next paper wallet in the list.

Yeah of course, I wouldn't like to see anybody lose any of their bitcoins because of some ass hole hackers.
I've seen some horror stories, one Chinese guy had 700 bitcoin stolen from a blockchain.info wallet because he didn't use 2FA.
Must have been heartbreaking when he signed in to see a 0 BTC balance.

Sweet thanks, I know a couple guys that might be able to help me.

It's not exactly trivial...you might need the help of a programmer
to set it up...take a look at this:

https://github.com/weex/addrgen/blob/master/addrgen.py

1. Generate a new address on bitaddress.org and print it.
2. Transfer Bitcoins to this new address.
3. Store the paper in a safe place.

ps: Do you think that Bitcoin will become more expensive?
Or do you want to save a trifle just in case?
