You can see the step-by-step guide here: http://www.coindesk.com/information/paper-wallet-tutorial/

Paper wallets are very secure as they can never be hacked due to the absence of digital keys but you need to keep them safely as it's still a paper and like any other paper, it can get damaged.

Thank you for the informations. In your opinion which is the best method of secured storing of Bitcoin? Desktop storing OR papper wallet storing?

Hardware wallets are safer than paper wallets as even though your paper wallet cannot be hacked, it can get burned, wet just like any other piece of paper and since you are storing money using the paper wallet, it will be very risky. Hence, many prefer hardware wallets due to the fact private keys are generated and stored offline and in case it's lost or stolen, your cons are never lost.

If you decide to create a paper wallet print two or three to have backups and then store the backups in safe places in different locations. Also think about laminating the paper wallet so the QR code doesn't get wet or ruined. You can pick up self-seal laminating pouches at the arts and crafts store.

I have never hear about bitcoin paper wallet. I even was sure that bitcoin hasn't any physical form. I have online wallet and one USB wallet, where I transfer my bitcoins from online wallet every week to feel more safe about it.

Thanks for posting this thread I lot some good knowledge about paper wallet and abou the methods of its creation. I love to get a paper wallet and I will shoe it to my friends who do not have adopted bitcoin and will tell them that it is a note of bitcoin. I hope after seeing it they will also adopt bitcoin.

is a paper wallet the has never been printed still a paper wallet? I dont print mine out i store them electronically all over the place encrypted.

But there will be no point to have paper wallet if you store that paper wallet details online or in your computer that is connected to internet. It will be more like storing in web wallet. Grin

Ecrypted? How using password on .zip file Huh

Digital documents, even after encrypted....can be decrypted.

No,if they're further secured with Digital Signatures,mostly no-access to a stranger would be granted.BruteForcing or Decrypting the hashes would take ages.

key and then posted it on cloud storage. This is stupid, because most online activities are logged and monitored.

That is the most convenient way a hacker can gain access to private stuff.

You print the paper wallet, and then laminate it, to keep it dry. Most digital media fail after a few years... so I hope you burnt some copies onto some CD's or DVD's

And make sure you keep it safe from a place full of rats ? Because they might shred paper into pieces. Undecided

CD's could re-written,their password access can be easily broken.

technically you can not call it paper wallet since that word means a wallet that is printed on paper!
if you are looking for a cold storage, then it is a different story.
as long as you have created the private keys offline and in a air tight computer and encrypted and stored them safely then you can consider it cold storage.

One of the secure method i use to generate paper wallet myself is as follows;

1. Download github of bitaddress.org from here https://github.com/pointbiz/bitaddress.org
2. Open bitaddress.org.html in any of your internet browser
3. Note that you have to open this from your offline computer or your old desktop which you will not connect to internet anymore.
4. Than now print that paper wallet you have generated by just moving your mouse on that page.
5. Put that printed paper with bitcoin address and address info in safe place note down bitcoin address to send bitcoin into.
6. Only import that address to wallet when you want to use that bitcoins.

If that file having only HTML and Javascript, no need for Internet connection for working.

I am also interested with Electrum. Many Bitcointalk users recommending Electrum. For that purpose, I will buy a laptop. How about external hard disc? I think it is also safe for store Bitcoin in Electrum. What is your opinion?

Electrum like any other tool is not just install an be safe, you need to make it safe. what i mean is going offline, making sure you downloaded the right file by verifying the signatures, running it on an always offline computer without any malicious software on it that may alter the result.

external hard disk also works but you usually want to connect that hard disk to a computer which has been online before and that even though may not do you any hard but it defeats the purpose of being cold storage.

Nope, I disagree. The whole point of the old second hand computer, is to eliminate all external access to any logged data by malicious software, that might reside on the computer. Even booting with another OS, will not remove that risk. Some malicious code are stored in firmware. < Take the Cisco routers as a example >

If nobody can ever gain access to that "offline" computer, then the private key generated on there would be safe. You will have to destroy the hardware, if you want to be 100% sure that nobody would retrieve any information from these devices.

This might sound a bit overkill, but if you are going to store 1000's of coins on these paper wallets or if 1 bitcoin goes up to $100 000/BTC, then you want these paper wallets to be secure.

I create 100's of paper wallets and then I push small quantities to them. If I need to use some, I do not have to sweep a single wallet with a large amount and then transfer the unused coins back to a new wallet. I just sweep a private key, and destroy the wallet. < You cannot re-use it after you sweep it, because the theory is once it was exposed to the internet, it is most probably compromised. >

well your answer makes less sense to me now. because you are talking about "malicious software, that might reside on the computer" and then suggest "buying a second hand computer from the internet!" so what is up with that?

and what you are saying is mostly being over-paranoid. and nothing is wrong with that but if you are thinking like that, there is a solution: stop using a computer to generate the private keys and go 100000000% offline.

how? i tell you how: use a dice to generate a private key.

Paper wallets were highly secure compared to other online and hardware wallets that's been used by the users. At any point saving entire bitcoin into a single wallet doesn't seem to be the better option. Personally I trust much on online wallets due to the high security feature it has.

Don't trust online web wallets no matter how many security features they have, you are relying on third parties to operate your bitcoins.

Regarding buying a second hand computer to create paper wallets it's too trouble some and more expensive than buying a cheap hardware wallet which has the best security out of all wallets out there in my view. Why creating trouble when you can do without it ? A second hand laptop will be costing minimum 50 Euro while a hardware wallet will cost minimum 15-18 Euro, specifically the Ledger HW.1

If have a scanner facility in your home, Scan the papper wallet and save it as a JPG image. Then store those images in any Hard disc, memmory card OR Pendrive. Jpg images never damage also we can use it any time. If need to print, we can take a print any time. I think saving as a JPG image is the best way for avoiding papper wallet damages. What you say about my opinion?

This is a good Idea. But I have doubt, Can we create papper wallet with that raw HTML files ? There is not using any Server side scripting like PHP and ASP? If no, no need to connect with Internet. If need to load PHP or ASP scripts, Not possible to create papper wallet without connecting with Internet.

since you only want to make a paper wallet i would say buying an old (second hand) computer is riskier than just using your own computer and it will cost you. if you are willing to spend then buy a hardware wallet.

and if you want to do it cheap then use a live linux without persistance as i suggested, you want to print the result anyways so you don't need to keep anything.

and as for that HTML file, it uses javascript to generate the private keys and it needs not internet connection, it only needs any of the modern browsers that support it. you can see all about it here: https://github.com/pointbiz/bitaddress.org
edit for screenshot:

p.s. in the end what you do is mostly a matter of preference. i run an Electrum wallet on my USB stick for instance

As suggested by Kakmakr and Pooya87, You can try this method as this is secure method as compared with other methods. Make sure you are taking backup of your paper wallet to other memory stick or paper and don't forget to take care of BIP-38 key if you have used that feature while creating paper wallet. It is the key you will need while importing funds from your paper wallet and you can add the bitcoin address on blockchain.info to monitor the balance and transactions as watch only address.

It can run on it's own, without the need of the internet. :-> The other option might be to copy the original source code from Github, but I prefer to do it that way. < I have done this for years without problems >

You might run into problems, if you move memory sticks between this "offline" computer and one that are connected to the internet, even if it is formated

I even bought a cheap printer to print these paper wallets, for about $10. Why spend $100's of dollars on fancy hardware wallets, if these paper wallets can be used for cold storage. ^smile^

BitAddress.org offers you what you need (I'm using it too). If you can, boot up a Linux Live CD on your computer to make sure all is going to be safe and that your wallets won't be stolen. Linux Live CDs are Linux versions that remove every change or new file you've created as soon as you power off. BitAddress is creating wallets offline too, so you can plug in your internet only until the website is loaded and then all is going to be offline. Print them out and deposit money on them and done!
