I know you can use blockchain.info but how many wallets have an 'import private key' option so you can transfer your entire paper wallet balance to an online or desktop based wallet?

I'm just preparing for the future because blockchain.info can't be the only option incase it ever goes down.

You can import private keys to all those common wallets like Bitcoin Core, Electrum, MultiBit and Armory. So you shouldn't need to worry about that.

Thank you.

i want for longterm holding. but what if that paper wallet gets wet or thrown away by mistake?

Create a paper wallet, also put password-protected wallet file on a USB drive.
Store both of these in a bank locker.

i was reading something about wallets with outgoing transactions are less safe?

so if i use my wallets it is less safe. what is best wallet?

If you are storing coins that you don't plan to use for some time then paper wallet or usb wallet that isn't plugged in is the best choice.

i have been reviewing different paper wallet tutorials and it is not that hard.
i will cover the paper wallets in plastic for extra security.

Make multiple copies. With bitaddress.org you can encrypt them as well. I have mine in different cities as well..

Learning how to make paperwallets (securely) should be very high on your priority list when storing substantial amounts of btc.

There's a lot of information about different wallets here: https://bitcointalk.org/index.php?board=37.0

I always wanted to ask: how does a trezor work?

To send bitcoin with Trezor, you just need to connect your Trezor to your computer and push a button to confirm the transaction. The private keys and transaction signing are done within the device.
You can find the details in http://doc.satoshilabs.com/trezor-faq/

There is no 100% safety. Even when using a brainwallet, at some time you will need to type it in if you want to move BTC to a hot wallet, and at this point there is potential for hacking.

Store your BTC on multiple encrypted paper wallets then when you pull one in you intend keeping the BTC from the one paper wallet as "spending" BTC.

Again however yes nothing is 100% safe is should be crystal clear police can do whatever they feel like so torture to get your BTC is very likely.. :S. Act dumb if anyone ever questions you.. I have a feeling dark dark times are coming.. pretend you lost all your BTC when they come.

Buy a Trezor Grin

Yea, everything you do on your computer can be cached or recorded and trojan's and phishing software can catch your keystrokes, thus gaining access to your passwords.

The best option would be, to keep the coffee budget online and the Lamborghini budget offline {Paper wallets} Grin

I think blockchain wallet is the best, for additional safety you can use BTC Trezor for larger BTC amounts. And think also on online wallet advantages over desktop wallets - are you be happy, when your desktop wallet will stretch keys for let say 3 hours. Wink

If it is for long-term storage, you're totally safe with a paper wallet that has been created on an offline machine that never connects to the Internet again. If the randomness is derived from a non-deterministic source, you should be really really fine, even without buying a trezor. A trezor is very nice for people who actually do transact their BTC on a regular basis.

You can make a few backups of your paper wallet. Also, you can laminate the papers to make it water-proof and more durable.

One of the best ways to secure your wallet is using the Electrum wallet software. This will generate a wallet with a seed of 12 words you can use to recover your wallet in case your computer fails.

Bitcoin on address (not wallet) with outgoing tx is theoretically less safe as its public key (not private key) becomes public.
So it is better to never re-use address. It gives you slightly better security and more privacy.
