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

I just bought a Piper printer

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

But not if you're meeting in a public place without access.

Then you should assume you got 0, future transaction or not.

What about using steganography tool to hide your private keys inside an image and then post it on Facebook ?

I can't wait for wide spread adoption. They'll be so many virgin sheep to fleece. lol

Currently on my main computer but if I ever got enough to worry about I'd store them both on a laptop and maybe a USB as well, I think USBs are too easy to lose though.

Good luck after the server recompiles the file

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.

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.

This is a really nice elegant solution! I like it a lot. But it sounds quite error-prone to manually create these transactions, so now I'm thinking about writing a utility that can handle it for me...

Naturally it requires one's next-of-kin to actually have a Bitcoin address already and know how to use it.

I do not consider magnetic media to be resistant enough to bit-rot.

Paper and ink has demonstrated that it can last for a very long time, if protected from fire and water.  But that is a big if.

Chiseled in stone appears to be the best long-term storage media.

And even simple format changes can help obfuscate.

I would hide a hundred usb copies around the city.

with this results: looks like hackers and scammers will have a great future...

What's your solution smart ass

What's your solution smart ass

As I said before doing the smartest thing would be using passgurdian on a private key or multiple private keys. Then distributing them to multiple people. So for example you can set it so that you have 10 keys and 6 are needed to decrypt the whole thing. so you could give out 8 of them or even just 5 of them. then keep 2 hidden somewhere and then put one or 2 on your will or something. and then one on a deadmans switch.

Oh come on, can you imagine Mr. Average Joe Dumbass doing that? Everyone wants a large corporation to accept Bitcoin so what they're holding is worth more. The problem is that large corporations deal with Joe and he needs protections to even be able to use his credit card and not get screwed constantly. US federal law limits the liability of credit card holders to $50 because Joe is so stupid he needs to be protected from himself. Joe could never (or is too lazy) do what your asking and will get raped constantly because of it. Honestly, a paper wallet printed automatically by some future client version may be too complicated for poor Joe.

This really depends on who you are blocking. Hackers? Paper. Government? Multiple encrypted copies.

[CaptChadd]

First off it is encrypted, which is obvious.

I then have it stored on five usbs, 2 mini SD cards and on 10 Hard Drives spanning multiple rigs.

Also the Bitcoin appdata folder is mapped across and not directly on the hard drive of the client.

Data engraved in stone


Although the amount of data we need to back up for Bitcoins is so small that you could chisel it in stone manually.

[Rassah]

Use it to back up the blockchain then

make take quite a bit tho

Use it to back up the blockchain then

that would be a neat idea. every X blocks back up the newest part ofthe blockchain to a disk
