Bitcoin Forum

I have created cold wallet address on blockchain.info and than print out paper and delete its copy from laptop. So it is now completely offline. Is this the safest way to store coin, as i think so.

Did you have also printed paper wallet and have it with you. For better protection i have laminated paper and put it in safe.  8)

i'll do it when i have lots of btc, but not now.
your copy on laptop actually vanishes or not, depends on the way u "delete" it.
and your paper wallet still suffer risks like fire, water, mouse, insect,...
i can see u did even try to lower the risk with protection, but in the same time draw more attention from the thieves.

I have created paper wallets before. I used an address from bitcoin core and not from blockchain.info wallet. I prefer to use an address which has never been "online".

Yes I have. But most of my paper wallets are BIP38 private keys so I can print a few and keep at different places. Not worry about them being stolen by other people.

Your paper wallet made from blockchain.info may be safe if you hide very well however and since you made it from Blockchain.info , your account can always be compromised if they (blockchain.info) get hacked .
It would be better if you use Bitaddress to generate the paper wallet offline and on Live-CD Linux and then you print it to make sure everything is okay .

exportprivkey command from wallet is way safer than online, but its rather hard

vanity generator is safe, and easier

Bitaddress, also very easy, but you might want to run them offline just incase

my paper wallet was from a live machine, printed off and no problems. im not confident that btc is widespread enough to have a common trojan targetting btc paper wallets.

dont use just one method to store all your coins is my advice. one mistake = all gone.

I do have a couple of paper wallets. I'm not too worried about thieves because not that many people would know what to do with that piece of paper. I think it's safe for now. This might change in the future when more people are adapting to bitcoin but I'll find another solution when that time comes.

I actually think it's safer to keep them in house (maybe a copy with family/friends) than it is to keep them on you... Chances of a paper wallet getting destroyed/lost/stolen when kept on your person seem to be higher than the chance of it being destroyed/lost/stolen when properly stored in your house.

I got some paper wallets as well but I don't keep them on me. I just keep it in a safe place. I prefer a paper wallet that has never been online as well. That's the safest way to keep a paper wallet safe. That way it can't be compromised unless it gets stolen.

I know that it's the safest way to store Bitcoin, but stupidly I never make my own paper wallet :D

I think offline wallets are the safest, I made a USB wallet just for trying but it looks safer than keeping it in PC exposed to possible spyware etc... paper wallets have a risk of being lost, burned etc... so keeping multiple copies in multiple safe locations is better imo. Also your wallet technically have a risk of being already exposed from being generated online if your PC was already being used or the site was somehow recording generated addresses

oh i know about papper wallet,and i can print it from blockchain.info.but i also not delete its copy from my computer,i do it for back up,i think i can be lost my papper wallet or my backup on my computer,so the easy and safest way is store your my bitcoin in many wallet. so far its really good for me,and maybe so many peopla do same thing like me.

Cool, it seems that this is completely safe

I will going to create a printed form when I have a lot of bitcoins.

be aware of the memory cache of your printed, it can store the private key, besides this, i find it more simple to do it via usb

store the wallet.dat there plus the whole blockchain just in case i do a secure erase and that's it, you have everything

do it with 5-10 usb(one new bought every new year) so you're safe about one not working in the future

I tend to agree with you that the chance is very low, but would you take the risk if you have a serious stack of coins? It is very easy to create an environment with a clean and resh OS, running linux to make a paper wallet. It is hardly more trouble if you have the right hardware lying around, such as a raspberry pi or something.

I don't keep my paper wallet with me everywhere I go. I print it out and try to keep it safe. I don't think having it with you at all times is exactly safe.
Paper could get damaged though, even if you do have a paper wallet, another back up would be good to have too, like having the wallet.dat on a usb.

If i had lots of BTC, that would probably be what i would do. Print it and store it somewhere in my room/house :D

No, i didn't have printed address bitcoin. I can copy it from my email

The first time I just didn't print my paper wallet I didn't knew what it was.
My paper is secure where water and fira can come in.

I dont have a paper wallet, mainly because i dont posess lots of BTC, so i just keep them on my computer.

I generate keys offline, they have never touched the internet/email/any web site. I create an encrypted partition on a bootable Linux USB key, with a 25 character password. My wife knows the password as well, so if I have a stroke, or die in a crash all is not lost. It would take several lifetimes to brute force the password, but it's a phrase that is easy for my wife and I to remember.

Rather than have "The One That Is Very Important", I have a dozen of them. One at my parents, one in my vehicle, one in my desk at work, one in safe deposit box, one with friends. They are all identical copies.

Inside the encrypted partition is a directory blatantly named "Bitcoin". I have public/private keys in a text file. I also have QR codes for each, generated/stored in there as well.

Because it's a bootable USB stick, when I boot to it in Linux, I am completely free from any possibility of Windows malware/keylogger/screenshot that could be present in the host PC.

Since I consider this a very secure environment, I also store other important things. I scanned the contents of my wallet. I have copies of my insurance, mortgage, paycheck stubs, eyeglasses prescription, I have exported my phone/PC contact lists, saved all my bookmarks. I have a huge zip file of important/personal family photos.

If I just did this on one USB stick, I would very probably run it through the laundry. With redundant off-site copies, I don't care if I lose one, or it gets destroyed.

I totally agree with you. Nowadays i didn't need paper wallet to bitcoin. Because my wallet only there some dollars. Maybe in future i will need that printed paper wallet.

That is a lot of work to achieve less security than you could have with a $20 Ledger HW.1 hardware wallet. At some point you will have to expose your private keys by importing into a wallet to spend. With the Ledger your private keys are never exposed.

Print it out and keep it in a safe place, never going to keep in on my person.

This depends almost solely on your safety practices, not much on the storing method...


First step to have issues, although I hope you don't have any.
