Topic: [UPDATE]Can this be considered a Safest Cold Storage?[UPDATE] - page 3. (Read 1786 times)
You may consider using BIP38 for paper or hardware wallet for additional protection. A random 6-character password will take many years for the fastest computer running 24/7 to crack. However, do keep a copy of the bitaddress.org offline for future decryption.
Rather than using an electronic device, you may consider a paper wallet instead.
When generated safely (offline on a computer that never connected to internet; complete format of the harddisk after generated the wallet), it should be one of the safest and will not be obsoleted.

To be "safest" when transferring the unsigned tx to the offline computer (and the signed tx back to the online computer) you'd be best to use QR codes (rather than USB flash drives as these could theoretically be compromised).
I would also recommend removing any WiFi card or other network card from the offline computer (to avoid it accidentally getting online).

So i installed Electrum on my very old offline PC which will Never be connected to the internet.I saved the seed and got bunch of address and private keys.I exported master public keys and imported these public keys on my Laptop that is connected to internet.Now it's watch only addresses on my laptop which is connected to the internet.
I can create a transaction on my online laptop and save it and transfer it to my old offline PC and then sign it and transfer it back to broadcast on my online Laptop.Now is this the safest cold storage? and will my private key leak after transfering signed transaction back to online Laptop?
And Electrum generated 10 address with private keys on offline PC which is Not connected to internet.What are the chances that any 1 of the address can again by generated by some other Wallet?
And one last question,Just in case my old PC goes out of bussiness and Does not start on some day then how can i recover my moondollars and even that possible to recover in such case?can i take backup?
I will appreciate some experienced bitcoin geak to please come and answer these.
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.
