Best long term storage.

Could anything last 50 years? Media wise only.

Some simple googling tells me that https://bitkee.com/ seems to sell metal cards with engraved information, this seems like a good choice if you're looking for something hard, fire and water proof.

paper wallet can last that long. but you should protect it .

I mean for example you could cover it with protected plastic which makes it last forever.

If we are talking about digital storage, you could use M-DISC.

Just use laminated paper wallets. We have a 100 year old book in our library within a glass box, and it's still looking
pretty good. The laminated paper should last much longer, because it's protected from external humidity. Just keep it away from direct sunlight.

I would not trust any digital media, because the technology and standards change too quickly.

You should check out this ongoing thread that talks about elaborate cold storage options: https://bitcointalk.org/index.php?topic=1175685.new#new

Also, here's a link that may help you decipher the pros and cons of different options: https://bitcoin.org/en/choose-your-wallet

I think that to many people will live more than 50 years. I think that the time will live more than 50 years. And at the end I hope with all my soul that you will last more than 50 years seeing that this is a disturbing problem for you.

Don't agree. The rain will destroy it if it will be rain for 50 years minus one day. Or some miners can destroy it for building .... homes for example. Or can destroy only for fun. To pass otherwise the free time.....

I have actually a 100 year old book (printed in 1917, so 98 years to be honest) in my bookshelf and it's in decent shape. Its covers are slightly worn and pages somewhat yellowish, but that's all.

A laminated a paper wallet will last even better. If kept in dry and dark place and avoiding disasters I'd say it will last for thousands of years.

My prediction : --> The most popular method of storing Bitcoin information will soon be 3D printing. The 3D printer market has grown phenominally fast over the last year or so. People will find very innovative ways

to print these addresses {Small treasure chests with hidden compartments or key chains with hidden QR codes etc. etc.} I think this might offer one of the best options to store this information. I am not a big fan of

normal paper wallets. It does not react very well with the slightest of contact with a heat source.

use acid fast paper or the ink will fade away. acid fast paper with acid past ink, then laminate.

great idea! I actually have a 3d printer. Just be sure to keep plastic out of sunlight or the uv light will degrade it.

3d printers that print metal are just around the corner.... maybe in another 5 to 10 years.

That's true, but paper wallets are very cheap and fast to make so you can store them in multiple locations if you are worried about burning your house down.

3D printed plastic will burn just as well and will probably degrade faster than paper in storage (plastic tends to dry and become brittle over time). Aluminum block can also be destroyed in house fires as the melting point is only 660°C. Stamping the private key to a stainless steel plate (melting point 1400-1510°C) would probably work better and survive house fires. (house fires usually burn at 700-1200°C)

you can always change your storage on a safe new machine, in the case of those usb stick, you can change it after 2-3 year if you feels that they will not fuction correctly

beaware of any printer which store in their cache the data printed, i'm not trusting any

This is a good point. If really paranoid, destroy your printer's controller chip after printing.

50 years? haha...probably you will want to sell with the next crash or rise or whatever  

plan for 5-10 years. you will do alot reevaluations in the next years.

Or you can just print it out on any of the old printers which don't cache the data . Plus I doubt anyone would know about your secret stack and will go to the lengths of getting out your printer cache memory.

Exactly this! Why would you want to store your bitcoins for the next 50 years? Is the OP planning on not moving his coins for that long?

I think that all you need to think about is at maximum next 10 years. By then, Bitcoin will either be dead or it will be huge. So you are either gonna sell them and make a huge profits, or you can just take your cold storage method and throw it into trash can all together.

And anything will last you 10 years.

I was under the impression that the materials many of them use aren't all that endurable. Maybe that's changing.

If I was to go for 50 years, which I think is a totally pointless time frame but anyway, I'd go for engraving metal or laminated paper. Most definitely nothing electronic.
