Where do you store most of your coins for long term storage?

[starsoccer9]

JPEG photos of a paper wallet, hidden amongst family and pet photo album archives. Even if you were staring the photo it wouldn't be immediately obvious there was a private key on it. I guess this could be regarded as steganography in its most basic form.

This is a really cool idea for a backup!

haha yea i thought it would be neat


Just to put everyones fears to ease. my main use in this poll is a few reasons

• figuring out where I should store my personal coins
• am looking into opening a service that will store users coins for them
• figuring out stats for the amout of users who would use my service

I used bitcointalk.org itself to backup my wallet import format key to the Internet forever and ever. Just string together the first letter used in each of my 51 first posts. Argh! You tricked me into giving up my key. Ah well, back to paper wallets.

PS: https://bitcoinpaperwallet.com is what I developed to safekeep my coins offline. I invested a lot of brainstorming & real-world testing with regards to tamper-resistance & long-term storage, waterproofing, etc.

I have all mine in instawallet and Bitcoin savings & trust. Around 2700 BTC.

You can also store a bulk of them in assets. A keylogger probably isn't going to care about your 2K ASICMINER shares.

Keylogger doesn't care, but it will get your password to your bitfunder account. So therefore, use 2FA. And try not to get any keyloggers by doing something stupid like clicking on .exe's sent by friends.

What do you guys think about the Sandisk memory vault or WORM(Write Once Read Many) SD card? Both last 100 years.

You can get a 1gb WORM SD card for $13.

That's cool, I'd get a few and put armory backups.

This might sound silly but I wrote the hex keys on 4x6 and put them in sealed manilla envelopes.

Next opportunity one is going into my safe deposit box and one (identical keys) are going into parents. That way if I die they can access them before waiting for the legal stuff to give them access to my box.

No QR code, no encryption, just written with a quality pen. Ink allowed to dry properly before putting the 4x6 into envelope.

Once they big enough, I'll look into that cool thing I saw where you can create a transaction that requires multiple keys to spend and put the bulk of it into that kind of transaction just to reduce the highly unlikely odds of someone getting my coins via collision.

Ummm so I bought 3 of them and I think they are fake.

I was able to write and erase, format, etc.. WTF? Erasing kinda makes sense if the space keeps decreasing. But it didn't, format brought it all back.

Help anyone? I don't think WORM needs to be initialized.

Most answers have revolved around hidden files, USB keys, scraps of paper, passwords etc. But what happens when you die?

Let's assume that you have some significant wealth in BTC, and that you would like your spouse or children to inherit it. How do you create a wallet that is both secure against theft but can still actually be spent by authorised individuals after your death?

My current thinking is a brain wallet saved on a USB key, deposited with an attorney. Give the password to next of kin, make sure they remember it but don't explain what it's for.

Actully I think the best way would be a private key encrypted with pass guardian and have the keys distributed to trusted people.

deadmansswitch.net can email for you when you die. The free version sends an email 2 months from now.

Alternatively, you can use google's inactive account manager.

PGP / GPG encrypt so no one else can read it. Your heirs better know how to use it.

You can create a bicoin transaction that will only be spent some time in the future. So what you do is:

1) Create a transaction that will send all your coins to a spouse or children two years from now.
2) Two years later, before the time runs out, move all the coins to another address, and if needed, create yet another delayed transaction.
3) Since the coins no longer exist in the address used by the original delayed transaction, that transaction will fail and be rejected by the system.

Rinse/Repeat.

That's a really great solution if you leave them on an active network. How do you do that and not expose yourself to risk?

You aren't leaving them on an active network. All you do is create the transaction, sign it, and broadcast it. You can create and sign it on an offline storage computer.

Ok but don't they need to be available at the time of the send?

No. That's why it's a transaction that will spend at some time in the future. You just create it, telling it that it can only be included in a block at some time in the future, and sign it once, and the network holds it until it's ready to be included and confirmed. You're not required for anything else.

That's a great idea. I've been looking for a solution to this dilemma for a while now. Let me ask you one more question about this. If I wanted to rip someone off then I could sell them a paper wallet that will effectively be worthless an hour or two from the time I sell it because I can set the coins to automatically just return to me. Correct?

[bitpop]

It's not a secret, they can see the future transaction. And anyone taking a private key better sweep it instantly.
