Title: How do I go about making a paper wallet?
Post by: marcotheminer on December 13, 2013, 11:20:27 AM
I would like to create a paper wallet. What would be a simple, quick way in order to create one.
Would the 'paper' option on blockchain.info be alright?
Thanks

I made a visual guide to create a paper wallet, the text is in italian but easy to translate

Yeah, works fine, but just make sure to read up on paper wallets so you understand the risks and how to minimise them.

what has been the most common mistakes with people losing coins via paper wallets over the years?

i heard something along the lines of you can only fund the paper wallet once? or is it you can only redeem on a paper wallet once & any other coin not redeemed get lost forever?

No, you can keep adding funds to it. Biggest worry is you can lose the wallet.

you can only spend out of the paper wallet once.

ok ty & 2 more quick dumb questions please:

1.) is it super easy to redeem your paper wallet?

2.) bitaddress.org - if i save the web page and go offline... refresh the page a few times how do i know whoever owns bitaddress.org doesnt have access to my private key?   & how has the offline page managed to communicate with the BTC network?...the new private key is truly random?

Here is something you should NOT do:

You have a paper wallet with 10 BTC, import it into bitcoin-qt to spend 1 BTC, then delete bitcoin-qt. The 9 BTC are lost.


Why?

bitcoin-qt sends the 9 BTC to a new change address that you do not have the private key of, once you delete bitcoin-qt.

It depends on the client you use to withdraw the BTC with. I would try to avoid those clients that don't let you choose a change address.

I dont get it why is no one giving the right answer....

1) goto https://www.bitaddress.org/
2) save the html page
3) disconnect your internet ( or load a live linux CD )
4) Open the saved bitaddress page
5) generate a wallet, print, and reboot.

This is the super safe way of creating a paper wallet you can be sure is 100% safe.

if your not paranoid about man in the middle attack, skip steps 2 to 4

I am quite concerned with the security issue. Is it safe enough to print paper wallets in shared printers? I can't afford a printer right now. Please advice me.

you really have to be paranoid to think someone will somehow hack your network and sniff what's being send to your printer

but these paper wallets will be with you a long time, take the time to do it right, and have no worries.

Well, you'll probably be alright, but not if you want to be super safe, and it's not a good idea if you're already paranoid. You could just write the public and private keys down instead.

or buy a physical coin (https://bitcointalk.org/index.php?topic=368598.msg3936943#msg3936943), and use that as a safe paper wallet.

there are many many ways to store bitcoins safely.

take some time to figure out out to do it properly, or spend some money to get piper  http://piperwallet.com/

Is this true?

Having a hard time figuring out if you can actually move part of a paper wallet and thus lose the rest or if its only possible to sweep a paper wallet.

Also, what is the reason paper wallets can't be partially spent?

Best way is to have an Ubuntu boot CD with the http://bitaddress.org on a thumb drive. Boot from the CD, generate the Public/Private key and print with a cheap "dumb" printer. That way nothing is saved to the hard drive or printer and you're not connected to the internet.

You can download bitaddress.org files at:
https://github.com/pointbiz/bitaddress.org

It's this file:
bitaddress.org.html
