[UPDATE]Can this be considered a Safest Cold Storage?[UPDATE]

[lolgato1]

I'm not sure if it's the safest but it seems very safe the way it is. Though it could be safer if it was a paper wallet. Though having to go through all that when you could just get a trezor seems to be quite a lot of work.

or are you talking about a project that you did (i remember seeing you post the link is some topic but i can't find it) can you give a link?

The CIYAM Safe (https://susestudio.com/a/kp8B3G/ciyam-safe) is another (more hard-core technical) approach to cold storage (which uses QR codes for communications).

The utilities "qrencode" and ZBar are basically all you need to use for that part of things.

thanks, i will check it out.
this https://github.com/ciyam/safe is the source right, cause i can't see it on above link

~~~
Electrum do have a feature for QR codes for transferring tx but it's useless if your bitcoins are stored in cold storage on old offline pc as that pc has nothing to scan the QR so i use USB instead.
I have antivirus and antimalware on both pc so it's pretty safe to just use USB

hmm, i have never used that feature cause i am too lazy to look into those extensions to add to Electrum.

you have to stop using Windows the privacy hazard all at once (lol)
when i say Electrum cold storage i mean using it on a Linux with all the network settings cut off + everything encrypted + keeping it on a linux specific format that windows can't even recognize
source that i used: https://bitcointalk.org/index.php?topic=853288.0

The link that I gave is to an Open SUSE "live distro" that includes the scripts from that github link as well as Bitcoin (although the version hasn't been updated for some time), vanitygen and other tools (such as the QR code software).

You are welcome to use any of the software (if you have any specific questions about the scripts then feel free to PM me).

I think you can't call it the Safest Cold Storage, it still need to be more secure to be called like that

[BitcoinSupremo]

I think this is the safest cold storage if you are running a more secure OS like Linux so even using USB drive only in Linux PC-s , you will be safe and malware is pretty low in this kind of OS so yeah sounds like a nice safest cold storage. I am being a bit bold as I am keeping all my BTC-s online in Electrum wallet via Linux ,saving the seed in a USB encrypted which I don't put to any Windows computer.

Well i am using Windows in my both (online and offline computers) and i have antivirus + antimalware both on my both pc's and my electrum seed + all private keys are in .txt file which is further archived in strong password protected .rar file . Isn't this setup safe?
and yeah that rar file is stored on external HDD and my online laptop too in case in future my old  offline PC gave up

it is safe but as long as you don't get infected by a new virus that your Antivirus can't detect in time. then you can easily transfer it to your offline wallet and infect that PC too. reading the topic I find what CIYAM proposed very interesting, but I don't know how easy it is to setup yet.

and also I want to add, for your private keys + seed I think the .rar password protection is enough as long as the password is a strong combination that can not be broken by brute force. but you can always encrypt the private keys (text itself) too for additional security.

Well how to encrypt the text?
All my private keys of all the address that electum generated are in .csv format which can be opened using notepad.On opening that file i see all the address with corresponding private key so how can i encrypt it? and how to decrypt when i need to use the keys?

You could use an encryption tool such as GPG for that.

Agreed, putting your bitcoin in a computer isn't save, since there's a lot of malware.

Putting your btc into usb is a smart thing, as long you didn't lose it somewhere that people could steal it.

than tell me what must electrum do to be safest cold storage?i think its already safest way to store our bitcoin,and of course if it compared with nline wallet or papper wallet,its low risk and high security,we all know that.

Sorry to disappoint you but Windows is never safe, a lot of malware appear in just 30 minutes time,based on Eset smart security updates so you are safe only if you knew 100% that your PC was safe when you were saving those archive with a password. If a malware was in, it could have stealed your pass and then your BTC but its a good thing I am guessing your PC was safe when doing all this, now you are in charge to keep it that way.

UPDATE:
My old offline PC gave up in just 1 day and doesn't start now but somehow i recovered the wallet using the seed and sended the moondollars to other address.I still can't figure out how to store my moondollars safely now.
I can't trust online wallets.I can't afford hardware wallets because they are too expensive.What are my options now?
Please suggest me guys how can i safely store my 7+ btc .I only have 1 laptop and an android phone.

Safest bet to store them online. Install Debian Linux (not Ubuntu as they are messing with Windows now). Install Electrum, recover via your seed, add a very strong password, put the seed in external HDD or USB. Thats the highest security regarding safeguarding them online. Other than that, offline or buy a hardware wallet. I have about half of your BTC and am keeping them in my Electrum wallet online  in a old version of Debian based linux system.

Since you have an android phone I recommend installing the Mycelium wallet and importing your private keys there. It's a very solid software wallet which even has uᴉoɔʇᴉq trading integrated if you need to buy some uᴉoɔʇᴉq. Mycelium also has the function to spend from Cold Storage. Now my advice is to create a paper wallet for $0 cost, put your stash of 7 coins on it, and when you are in a hurry to spend from the cold storage just use Mycelium and load your paper wallet and after the transaction is done all the details will be erased. So in short zero costs for you at maximum protection.

This sounds interesting but i have heard when spending from paper wallet you need to spend the whole balance otherwise the remaining balance gets lost.is it true? Suppose i have 7 BTC in paper wallet and i need to send someone 2 BTC then i use Mycelium to do it.Will my 5 BTC remain on Paper Wallet? and are you really sure once i use Mycelium my private key will not be stored on the device?

Surely you can afford a hardware wallet if you have 7+ moondollars. You can get a Ledger for $15-30. I have a Ledger nano and it works great. I highly recommend you investing in a hardware wallet if you want to be sure your uᴉoɔʇᴉq is safe.

Edit: I highly recommend using a Ledger with an OTG cable to connect to your Android phone. It works flawlessly with Mycelium wallet.

but shipping charges are $40 and i don't know how much more can it take at customs so i don't want to buy it

Well obviously it is up to you, but $70 ($30+40 for S&H) doesn't sound like much to pay to secure $3,000 (7+ BTC).
