You could also carve a private key into amber (a fossilized resin) which has preserved insects, sometimes for millions of years. Sadly if heated above 200 °C (392 °F), amber suffers decomposition, but I doubt it weathers as badly as stone. Here's a picture of an ant preserved in amber.

I suppose you have already heard of Mr. Bitcoin but I think this is the future of bitcoin storage.

These NFC tags can be used for a variety of purposes but we like to see them as subdermal Bitcoin Wallets that enables one to securely store digital cash under one's skin.

[Wendigo]

Well your smart phone supports nfc technology so your kids could get your secret stash any time they want when you are gone without having to use the kitchen knife  Anyways I would prefer some small chip than the need to lug around hardware wallets. I do fancy the idea we will be carrying the blockchain in our bodies in the not-so-distant future

That needle looks big! I wouldn't do it. I wonder if this thing is vulnerable to EMP or strong magnetic field? What if the carrier gets tased?

I was thinking about long term wallets and how the steel wallets are neat and paper wallets are fine but what about a long term wallet to last for hundreds of years,

You are on the right track i to had these thoughts and i finished up when i remembered something from school 20years previously we dug a hole and buried a time capsule.

You could in grave a stone deeply and then place it in a time capsule 'steel casing' and then it is as safe as can be from anything and everything for as long as needed.

Personally I don't think that you will be in need of bitcoin wallet in a say, 100 years. Not that you will be long dead, thats too. But I think as for technology
it is safe to assume that bitcoin will be upgraded to the point old private keys would be obsolete and not needed anymore. It will happen sooner or later,
with bitcoin 2.0 release.

Woah, thats sick and crazy. If someone would want to rob you, he would cut this from you with knife.... even more sick.
This is really bad idea, i would prefer amber

Houses don't last. I regularly see old ones being demolished with apartments buildings replacing them. So I suggest you build a pyramid atop of the stone in your basement where you've carved your private key. This is time-proven, I've never seen anyone demolishing a pyramid.

But you gonna need quite a lot of big stones.

So are you saying that quasi-immortality isn't even going to happen, or are you just saying that current young BTC holders will not be rich enough to afford it?

1) Tattoo password/phrase on taint 2) Implant under skin containing encrypted private key or wallet in armpit

Put in your will that you are to have an autopsy and where to look.

I don't know about stone but I prefer metal. Even at high temperatures like fire which goes over few thousand degrees when it is burning, stones or even concrete for that matter will be reduced to rubble. It's the same for metal as well which will probably melted and if only one of the characters were missing, it will be very difficult to recover. Still cracking my head on what is the best solution though.

I am afraid that you can't be and you wouldn't be so rich with bitcoins alone. Bitcoin is not independent enough. It is being manipulated easily by whales.
Do you think that 'old money' would allow bitcoin to spread and gain more value in the future? No, they would probably buy good amount of coins and will be (already are) manipulating market.

If you like metal but are concerned about heat, have you considered implementing a MultiSys (multi-solar system) solution?

[Hfleer]

Why are people concerned about >100 year storage. you can just renew your metal wallet/paper wallets once they lose some of their qualities.

Consider engraving your private key into a block of tungsten



With a melting point of 3422 °C if would be the only thing left if your house burn down.
And with approximate same density as gold, the block is rather heavy to pick up and run away with.

I would love to see this. Sweet idea.

and therefore super easy to hide :p

Imagine smuggling some of those around in your ass if you have more than one address.
