Topic: Can someone tell me which is the most secure of the offline wallets? - page 5. (Read 6813 times)

Ok, let me attempt to answer what I think is your question. Or rather should I ask: how could it possibly be the "word around town" that duplicate addresses are that easy to generate by mouse movements? That town obviously has no idea what they're talking about. What I have always heard was that it is near impossible to generate the same Bitcoin address twice. Like picking up the same grain of sand from all the beaches of the world.

Brain wallets are not safer - unless you're extremely smart and can remember a brain wallet after forgetting about it for 40 years.

And to answer the rest of your question, Go with what Litecoinguy said.

Well you need to have physical access to potentially spend any bitcoin controlled by it so even a weak PIN will somewhat secure the bitcoin it "protects" as long as the RNG is sufficient to generate a private key that is truly random

In what way is thast better than trezor?

everything but a savvy PR guy, ppl be thinking "Bank grade?? 4 digit pin an that's it???"

I saw one of these the other day and I was pretty impressed.  they seemed to have thought of everything.

You need to be online in order to sign any transaction with multibit (you need to be connected to multibit's servers). You could potentially use multibit to create addresses on an offline computer and use it to store the private keys, but I really don't see the point to this

yea! bitcoin core is the more secure wallet

That's right !!! I made a very big mess !!

An online wallet is a wallet that is hosted by an external website. And can be accessed from any computer with internet access.

Offline wallets are stored on your local computer and can usually only be accessed on that computer.

multibit doesn't require to download the whole of the blockchain and can be used as a offline wallet I think bt armory and bitcoin core are the ones to go with if you want a secure offline storage.

but multibit is one online wallet! or not? maybe I'm wrong, but is online

Bitcoin core is the wallet offline secure

Well the only "wallet" service that can technically work "offline" is armory. It allows you to generate private keys with an offline computer and then when you are ready to spend your bitcoin you can create a TX on an "online" computer that can then be signed by the offline computer.

I think your question is misguided. You probably want to know how to store your bitcoin offline. For best security, you will want a computer that has never "touched" the internet (meaning never connected to the internet). You then will need something that can generate a private key for you, I would recommend bitaddress.org (their git hub is https://github.com/pointbiz/bitaddress.org). If you choose to use bitaddress then you would need to transfer a copy of the site (generally via USB drive) to your offline computer. Then you create a private key (the public key will be shown as well). You save the private key to your offline computer (and you should back it up to a second USB drive as well - at the minimum). You can use the QR code for the public key to save to your online computer so you can transfer funds to your offline computer.

When you are ready to spend your offline funds you will need to repeat the above process for a 'change' address, copy the private key onto your online computer to send a TX to your hot wallet with the change going to your 2nd newly created offline address.

I know this is not 100% what you were asking but it should help you get to your ultimate goal

Surely, a hardware wallet like ledger HW.1 or Trezor that you use when you need to and then lock it away somewhere?

At least, that's what's suggested on the website?

Electrum is a good choice because it will give you cold storage as well.

I think Trezor - it is simple and safe device  Can change let say after 8 years to new Trezor, because of possible Trezor parts fail ( for example - Trezor buttons after long term use ). 

I think it's just the case that people are just trying to bring forth various considerations, in order that you may make your own decision.


If you wanna get told what to do... well I think I saw a Mistress for BTC thread or two...

Its because you're unable to comprehend the answers.

You can use armory and make the transaction completely on a non-networked PC. Look it up.

Armory is pretty sweet.

i would like to choose Bitcoin Core also mSIGNA & Armory is a good choice too always be careful

with all due respect.
None of you succeeded in answering my question.
I don't know maybe I didn't write it properly or perhaps I am misinterpreting the comments . Maybe I am in the Matrix I just can't believe in all these comments no one answered my question.
