can someone link the sites to some paper wallet and hardware wallet information ?
it should be legit .

Good! But don't use it online. Download it and use it locally.


Thank you!

wow Thank's for all reply it
i will create new custom address and claim it to Bitaddress.org

any way i send you a litle tip for help me
i send from xapo you will receive it soon

That's not it! There many problems. Some of them are:

 • You are importing your private key to an *online* wallet.
 • There is no way you can assure that they *actually* delete private key from their wallet.
 • When you expose private key to internet, there are many plausible attacks.


You can trust Bitaddress.org more than you can trust Blockchain.info. Besides, you are running Bitaddress.org completely offline which is secure than Blockchain.info which is completely online. Just think for yourself. Anyway, I am not compelling you to use Bitaddress.org. You can do what you like. Only thing I say is, what you are doing now is a bad idea. There is a high chance for theft.


Not really. Hardware wallets are less immune to computer viruses but these USB sticks are.


You are not installing anything on your computer. You are creating a live USB.

Read https://en.wikipedia.org/wiki/Live_USB and http://instructables.com/id/How-to-make-your-own-Ubuntu-LiveUSB/?ALLSTEPS.

P.S. For creating live USB, I prefer UNetbootin over Universal USB Installer.

that like hardware wallet ?
look interesting but im use windows 8
any method for windows user ?

i personally prefer using an offline linux for storing an offline wallet as my cold storage.
the difference between this way and using a paper wallet is that i can use my bitcoins any time i want without needing to sweep the keys in an online wallet.
i used this post https://bitcointalksearch.org/topic/diybitcoin-cold-wallet-usb-stick-creation-step-by-step-guide-853288 as a reference to make my own custom offline wallet.

i remove key from blockchain after i print it
i think that  good for me

any way im not trust bitaddress.org

Instead consider using Mycelium on your phone. Mycelium has Trezor support so you have security and convenience, just have to carry your Trezor with your phone to send bitcoin.

That's certainly not a good idea! You are importing private keys into an online wallet to create a paper wallet? This is not secure. If you are using online wallet to get qr code, then use BitAddress.org. Download BitAddress.org and after creating vanity address, open BitAddress.org HTML page and go to 'Wallet details' and enter your private key. Then click 'Print'. Or you can use a simple qr code generator and print it. Don't use an online wallet to create paper wallet.

for create new paper wallet i choose vanitygen
i create new custom wallet address like 1shanexxxxxx (using command prompt)  after it i use blockchain to import my custom bitcoin address, and i export it to paper wallet 
need more step but i like my way i trust blockchain

You got it!

And @Frosten, in regards to the building a new PC thing, it shouldn't be a necessity, TBH. But there were a lot of theoreticals thrown around in 2013 about being able to infect the BIOS of systems and a logger as well, that may be able to exploit things in some way. That said, is it a concern? I don't believe so. But it's better to be safe than sorry if you're storing a lot.

Yes, if you know the source code of the script and the compiled version matches, it will be safe.

Muhammed Zakir, Thank you for a comprehensive answer.

I will go with BIP38 encrypted BT Papers.

Answer to Ranio, I don't feel the need to build a new computer and just use that for creating the keys, I will go somewhere in the middle, but it's easy be paranoid when you realise how much that can go wrong. But I'm not talking about my lives savings, but I still want to make a best effort not loosing it. First I need to understand the technology before investing larger sums.

1. Using a live iso (linux) on a usb stick, checksum the iso
2. Download the generator on a separate  usb stick check sum it
3. Generate and print the papers  

BurgerKill, if you want to make sure a computer never touches internet you basically need type it in. But if you checksum the file before a transfer you can be quite sure that no one has tampered the file. But the USB interface is not secure it has it's drawbacks, it's a design fault. Maybe you can hand write a BT paper if you are really paranoid (That doesn't mean a bad thing).  

For the hot wallet I think I will use the original Bitcoin wallet (If no objections?). Is it possible to use the same wallet on different devices, I mean my phone and my laptop? It would be convenient. I will avoid using online wallets, a friend lost about a few hundred  BT, think it was MtGox or something like that.

How are you supposed to download a script if you aren't supposed to get online in the first place? Download a script to a USB and then transfer the file from the USB to the computer?

I'm still new to paper wallets so forgive me if my question seems like a newbie.

If you want the truly safe way to make a paper wallet, you have to do a couple things:

1) Find a PC that has NEVER been online (i.e., building one yourself with brand new parts -- while it hasn't been seen yet, people say you could even infect a bios)

2) Download one of the scripts for generating cold wallets

3) Generate it on that system

Never take that system online. If you need to transfer from it, sign the transaction there and use a USB drive to take it to another system where you transmit it to the network.

I think it is bad security to use anything online to create an offline wallet. There are guides that show how to create and address/priv key on an offline computer, preferably a live OS cd.

i always use bitcoinpaperwallet.com. it is the best i have had nothing to complain yet. but i am not a cryptoist.

If your intention is to only store funds for a long time then why don't just install electrum on an offline machine, send funds to one of it's address and just make note of its seed somewhere safe, then when you need to use the funds in future you would only have to restore the electrum wallet with it's seed and you'll have your funds.

This is what I am doing btw, I don't have any paper wallets or trezor or any other cold storage device, just an electrum which stays offline and I remember it's seed and I have stored it down somewhere in-case I ever forget it. And that's it.
