I had one paper wallet created as an offline wallet. I know how to import it on blockchain.info. Can anyone tell me that how can i import that address, along with private key to bitcoind on Ubuntu using command line?
If your wallet has a password, use this to unlock it. (space)bitcoind walletpassphrase yourpassphrase 120 Next, to import the key, you have to use this. (space)bitcoind importprivkey "5PRIVATEKEYYYYYY" "LABEL" You have to unfortunately type the entire private key word by word, it must also be case sensitive.

Don't I have to type in the address somewhere along with the private key? Or the address automatically gets imported. Thanks for all the info though.

I don't know any wallet that requires you to do that either. Address is easily retrievable from the private key.

Public keys are easily calculated from private keys. Private keys are nearly impossible to calculate with the public key (brute force very large key space required). One of the great reasons Bitcoin works!

The best option and most secure is a paper wallet.
You can make one via many websites, eg blockchain.info

If you make the paper wallet from blockchain it kinda defeats the purpose. Blockchain is a hot wallet.... so getting the wallet there for the cold wallet is not the best idea. There are much better way's to get paper wallets. Do not get them from a hot wallet or you still have all the security risks of the hot wallet you got the private key from (in your suggestion this would be blockchain).

Blockchain.info stores your private key on their server and hence isn't secure. Encrypted or not. Instead, try downloading bitaddress.org. They offer userfriendly UI and secure generation. The paper wallets also have a Qr code on it. It is more convenient when using it with mobile wallets.

nah it is not the best, there is the well known problem with the printer and their memory i find usb much more secure, if you buy many of them, and much faster and i would avoid webwallet like the plague, for anything really...

Why dont you try paper wallet.They are more secure unless you live in a disaster prone area. You can create one at blockchain for free.
I thought a seed was a paper wallet, no?

Paper wallet its not best option because paper wallet susceptible to water and also easily lost.
I think better using usb stick or hardware wallet like Trezor not easily lost and more faster to use. You can easily place backups at different locations and laminate all of them for waterproofing. It is a cheap option to secure your Bitcoin. USB thumbdrives are likely more vulnerable to water damage though. Trezor is water resistent but not waterproof. It's very expensive too. Why dont you try paper wallet.They are more secure unless you live in a disaster prone area. You can create one at blockchain for free.
I thought a seed was a paper wallet, no? Technically yes. But some seeds are only used by a specific wallet client for generation and isn't universal. Arguably, private keys are accepted by all the Bitcoin wallets.

Arguably, private keys are accepted by all the Bitcoin wallets. Technically the Trezor really depends on how many coins you hold. For a wallet of 1 or 2 yes very high. But if a decent sized holder it really is not horrible. And I would get the private key. With the private key you can put it in most any wallet. And really paper wallets even if laminated do not withstand fires, so I would not just keep copies in home as if something bad happens... it could burn with the home which would be horrible ontop of horrible. If you have a safety deposit box at a bank that is best spot for paper wallet.

I think they stopped producing them but they are still available via Amazon etc... Mycelium had a USB stick on the market that generates images of paper wallets when inserted in the USB slot of a printer. The printer sees it as a regular USB stick that has the image of the wallet on it, with QR codes etc... Should be totally cold that way. https://mycelium.com/entropy

Paper wallet has always been my best bet. Hardware wallets really are kinda taking over in some aspects. They will never take over paper wallets completely, but a hardware wallet that can send even if using on compromised computer like Trezor and still be secure... is impressive. Paper wallets are great long term storage but when you load a paper wallet into a wallet and use it, is when you have some possible security risks.

A lot of replies here, let me give you the best option, for a large quantity of coins forget the trouble of paper wallets, cold offline storage, I am sure you can buy a hardware wallet, I recommend trezor , but if you want a cheap one even Ledger Nano does the job for just 20 USD. If I had large quantity of coins over 10-15 I would buy one.
