I have a wallet on blockchain.info and another on my machine using bitcoinQT. For both I have the latest print out. Now if...

1. Somehow I cant log into blockchain.info, then will I be able to use my coins using my paper wallet ?

2. Somehow the data file of my bitcoinQT gets corrupt, then will I be able to use my coins using my paper wallet ?

CoinDream, a paper wallet is not a backup. It doesn't duplicate (make a copy) of the keys in your online (blockchain) or software (QT) wallet. The paper wallet is created by actually transferring the keys (critical information) from the online or sofware wallet onto printed paper. What value you transfer to a paper wallet is no longer on your other wallet(s), until such time as you would transfer it back.

So you can safeguard your holdings by transferring them from other wallets to a paper wallet; but then, they will be unavailable for you to use in your other wallets till you transfer them back. The paper wallet kind sets them aside for safe keeping in a vault or very secure location. If you lose or damage funds stored on a paper wallet, they're lost forever.

Unless you have a substantial amount of btc, you may want to simply backup your QT wallet. Those instructions are readily available. A backup of your QT wallet is a copy, like any other backup file. It's just an emergency saviour if anything happens to your QT wallet. You can just import the backup file into your program, allow it to sync, and you're good as new.

You cannot backup your blockchain wallet. Online wallets are left totally to the protection of your provider. That's generally a good reason to store most of your value in your software wallet (backed up) or paper wallet.

@allgoodthings1 Thank u so much for the explanation. From this what I understand, software wallet backup is the best option. But recently I have heard of a virus that, if gets installed to your machine, will transfer your bitcoins to some other address. Then, I guess, my data backup wont be of any use. On the other hand, most our current anti-viruses are not updated with Bitcoin virus definition. So, it remains risky to have Bitcoins in own machine !!!

On another instance I saw in a thread that one person did 2-factor authentication blockchain.info wallet. Now the wallet is not opening with 2-factor authentication !!! So, the person is able to see his coins, but unable to use !!!

backup ur wallet on flash drive so u can export it to blockchain
or from blockchain to wallet

I recommend  for you to back up wallet at several places,

but the key is a strong password that you never forget. Unfortunately I forgot the passphrase of my namecoin wallet and now it is useless;(

Make an offline wallet, store it in a netbook, flashdrive, old HDD, never connect it to internet, also make sure to back it up.

I would suggest: copy the wallet.bat to 2 usb keys, delete the original on your pc, encrypt both usb keys. Then store the pw on paper or on another usb key with other passwords say.

When you say back up your wallet, do you mean to just copy the .dat file?

First of all @OP you have to do a backup then try to recover your password if you can't login to your wallet account.

If u try to xplain these security aspects to a non-coder, he'll say "My leather wallet is the best"  :P

u need a backup on a usb drive :)

How to create a 100% secure wallet today ?

The only way to secure your wallet is to give a strong password.The password should carried different characters,capital letter,small letter,different types of sign etc.If you make a password through the above hints then I am quite sure that your wallet will be secured.

yes i have no idea about this question .so i want to know how to secure my wallet and anyone don,t hack my wallet ..please tell me about it.

There are many ways you can store your bitcoin. I usually divide the number of bitcoins I have into sections to keep depending on my purpose. When I trade, I have to trade bits and pieces on commercial sites, and I also use online wallets like coinbase and blockchain to store bitcoins. I also keep bitcoin on hard wallets like Trezos and Nano S to secure the property that I have. Remember to keep your private key confidential so that it is not stolen.

Save your password or key in the secure account like on gmail and other mail. Do not share your password make it private to avoid theft or lost of money or token. You have just put a recovery account or your number on cellphone .

yes paper wallets will give you access to you coins. But for bitcoin-QT you had better backed-up your wallet.dat file, as there are a number of private keys in it, not only one.

Also, if you have any considerable amount of your holdings in crypto, buy yourself a hardware wallet and secure your coins once and for all.

The hardware wallet is secure even if stolen or lost because it is PIN protected and you can recreate your wallet on a new
device from your 24-word recovery seed. That 24 words is something that must be protected and never disclosed to others.

Then, after all your funds have been secured, it is OK to keep a fraction of it online (on blockchain.info or others).

At least, it is what I would do.

Hi can I ask a newbie question also? Which is best option on securing a wallet offline or online? Also how to do it on offline?

I think you can use hard purses to protect your BTC or any antcoin!
:D
 

If you plan to keep cryptocurrency for a long time, then use hardware wallets such as LEDGER NANO S, or install a wallet on an old smartphone, disconnect the Internet, transfer coins to it and turn it off. If you need to make transactions every day, then it's better to use web wallets. For bitcoin - Blockchein Info, for Ethereum and coins on ERC-20 - MyEtherWallet using MetaMask.

Bitcoin allows you to transfer anywhere in a very easy way and allows you to control your money. The great feature also comes along with high attention to security. Bitcoin provides a very high level of security if used correctly. Always remember that it is your responsibility to take good security precautions in order to protect your money.

Private key was the only key to protect your wallet and to make it secure. So you need to keep or save it whenever you want so that you can easily open your wallet account. You can use your email as well as a back up to recover it. I recommend to use wallet that is appropriate to your country for example here in philippines people used coins.ph as a wallet for their money.

People are arguing now about bitcoins whether they will be the official currency or not. What do you think and why?

You made a shit here bro. If you want to use the thread to be discuss for other things you need to check with the op. If you have any query you need to create a own and discuss about it.
You question seems weird if you does not feel bitcoin as a currency you would not be in the forum. There are many people here in the forum to learn and earn. I do not think you are not for both stupid.

Looking back, I feel, how naive I was...  :-\

In my opinion copy your wallet address to 2 separate usb delete the original on your pc, encrypt both usb keys. Then store the pw on paper or on another usb key with other passwords say.

You can save it on a hard wallet
And save your private key is a secure place

Never screenshot your private keys and keep in your phone. Write it down somewhere safe and keep it where you are the one that can access it. Also activate two step verification.

Keep your passwords safe, make sure you are the only one with access to your coins. Be very careful who you transact and do business with. Never give out sensitive info.

The most secure wallets are hardware wallets so you should get one if you can. But if you have an online wallet then always keep your private keys tto yourself.

I recommended  to backup wallet to secure it, make an offline wallet make your password very strong that no one can easily know it that only you know it, your password should carried different characters,capital letter,small letter, etc. and make your to yourself that your wallet is really secure.

Keep your passwords and private keys safe in place where you are the only person that can reach them. Write them down in case you happen to forget or something happens to your gadgets

You should move all your money to a hardware wallet. It is the most secure and convenient solution existing today and it will address all the issues you list in the OP. Keep crypto online only when you want to trade it.

1. Make sure your pc have an updated anti virus.
2. Never give your security details to anyone, there are some airdrops scam that asks for these details so becareful.
3. Bookmark trusted websites you are using.
4. Buy ledger for your coins if you can.
5. Always doubt when the deal is too good to be true.

Mining bitcoin No one. No one physically prints the Crypto-currency, unlike the central banks, which can initiate an additional, uncontrolled issue of money to cover government debts, which ultimately leads to a depreciation of cash.
