It turns out there's a tiny gotcha bitcoin paper wallet security "paper wallets" that could lead to disaster if you're not careful.

I've been wanting to get into "cold bitcoin paper wallet security of my bitcoin for a while now. I've always heard that "paper wallets" are more secure than "hot wallets". So, decided to do some testing of my own bitcoin paper wallet security see how it works.

Always use a small amount of Bitcoin when testing out paper wallets. I used 10, satoshis on my first test So, let's say you received 3 transactions of 2. So, now you have 8. Well, yes and no. You actually have 3 tokens, each representing 2. Bitcoin wallets hold coins in the exact amount they were received by the wallet. So, when Bitcoin breaks a larger coin into pieces to make a smaller payment, there is an amount remaining that is considered the "change" back.

You get 25 cents change back. The problem is that the change goes to a different address!! You have to specify that address or you lose the BTC. When I sent my first test from bitcoin paper wallet security paper wallet, I did not create a new paper wallet for the change. I assumed the change would be sent back to the original address When you need to spend bitcoin from a paper wallet, the full amount of bitcoin should first be swept into a wallet like blockchain.

My advice is, don't try and spend directly from a paper wallet unless you really know what you're doing. If paper wallets scare you, but you need better security A hardware wallet is a special type of bitcoin wallet which stores the bitcoin paper wallet security private keys in a secure hardware device.

How did you "spend" the coin? If you used a regular bitcoin client, it should have automatically created change addresses that would hold the change and therefore be in your control. I think he over looked in haste, easy mistake to make though!

Thank you for sharing this information. I would have assumed the same thing you did. You have helped a lot of people! You can also use a ledger nano S https: Or you can import private key in Bitcoin qt, but using blockchain. Yes when you spend bitcoinsthe "unspent" bitcoins will go by default to other addresses, but these addresses are inside your wallet You don't need to any third party wallet provider like blockchain.

When you do a transaction, check in the blockchain to which addresses the unspent bitcoins went, then open the console in the bitcoin client and write dumpprivkey [Address], you will get the private key of those addresses in case you want to store them or you can simply send all the bitcoins back to the original address, in other words, you never lose control of your funds, just they are sent to other addresses inside your wallet.

By default bitcoin sends the unspent coins to other addresses so bitcoin paper wallet security harder to bitcoin paper wallet security the flow of the funds. Great tip about paper wallet.
