Long-term storage

How safe is to keep some BTC in the coldwallet for 20 years paying no attention to crypto world?

Edit:
lets define some conditions:

1. Cold paper wallet will be kept secure
2. Wallet owner will not have possibility to monitor crypto scene

Hardfork is not a threat imho, as the coins will exist in all future chains.
The only issue I see is private key bruteforce (quantum computers, etc.)

What else? Except for the price decrease

How safe is storing BTC in coldwallet for 20 years without regard to the crypto world?

I think it is safe but because this is in a long time, it should be often controlled walletnya, so selau can update the data

Not safe. Hard forks might occur that need your attention to prevent loss. At least use a hardware wallet, keep the firmware up to date, and check both your wallet and the forum for news every couple of weeks, at least once a month. Store the seed for your hardware wallet securely, not online, and keep a spare around in case of malfunction.

If you'd use a hardware wallet, wouldn't hardware failure be an issue?
If you just store them in a paper wallet, would your coins be compromised due to a hard fork? I mean just any hard fork?

Let's assume that wouldn't be the case, then I'd think a paper wallet might be the better option, if you're using thick, laminated paper...

Just like you said, I think a paper wallet could be safer since there is no chance of hardware failure. Not that this is a major issue since most hardware wallets are made having long-term durability in mind. Just store your paper wallet in multiple banks and you will probably be okay. Also, if there is a hard fork and you are storing your btc in a paper wallet, the way your coins are affected depends on the wallet you use to claim your btc.

Modern storage media can fail within a span of 20 years, even if they remain unused.
This problem is also known as data rot or data degradation. Basically the wallet could become corrupt after all that time. More info: https://en.wikipedia.org/wiki/Data_degradation
Use a paper wallet instead.

Make sue to give a period to maintenance your wallet and never just try to leave it for 20 years.
Imagine the sha 256 will be broken and all of the coin migrate to the sha 512. And there is a lot of cases need to be determined by you.

Buy trezor; it is a hardware wallet and good for long term purposes it is safe and virus and malware proof so you don't need to worry for the possible internet or online attacks to your wallet all you just need to do is to buy it and deposit your bitcoin and keep it on a safe place and just ignore it for 20 years or more.

Thanks for the information but 20years is to far right now bitcoin starts 2009, there is a lot of things will happen, more upgrades in every system of bitcoin wallet even in bitcoin itself. More people getting rich because of holding for long period of time. And im the one wishing that i would be rich here in bitcoin.

This is one of the worst idea I have ever heard. It is nice to keep your bitcoin in long years but if you would not pay attention to the crypto world and there are some major updates then you will miss it. There is a huge possibility that something will replace bitcoin and you will no longer knew it. Observing the market is really important since it will protect your bitcoins, asset and capital from being burned.

Not safe as others have suggested. I agree with Trezor as one of the safest hardware wallet you can get. It maybe expensive, but you can get your money's worth. And as far as not paying attention to crypto world is concern, for me its not also good idea. You have investments, why not pay attention from time to time to see if your investment has profit or not? The only thing can someone will make to do such, is that your are investing what you can afford to lose, so it doesn't matter for you to look at what is current price or what is going on the crypto world.

Keeping some Bitcoin in cold wallet for 20 years without paying attention to crypto world is not a bad idea. For me it is a good plan even if you only store 1 Bitcoin in your cold wallet and everything went well in the future then you will profit. It is like investing to some company that has a contract that you will not be able to divest your investment until x years will not met. 

[Dudeperfect]

I don't think there will be any problem with it until you have secure, recoverable cold storage because you can any time recover your funds from your private key and even though the software versions, exchanges will change drastically the core thing that is private key would never replaced by anything else so if you are planning to go with a cold storage then go for it but as I said, take extreme precaution for maintaining security as well as natural threats such as wear and tear of the paper.

[megynacuna]

It's like burying gold dust or gold in the sand and hoping it will fetch you twice the price of today in ten or more years and completely forgetting about mining. I think that would be very careless on your part to forget the cryptocurrency world while you have your bitcoins in storage for a long time because there can be moments when you can sell for high prices but you'll miss those chances because you're off the cryptocurrency world.

[Hydrogen]

20 year cold storage only works if the price of btc continues to rise.

It would guarantee you sold at peak value in a best case scenario.

Which probably means you held bitcoins and sold them years ago when they were worth much less like I did.

This is also one of the best investments with the risk of loss / loss is very small, but can provide a very remarkable advantage for a long time

It all depends on what you think is going to end up happening with crypto over the course of 20 years and there aren't any ways to get even a rough idea of what Bitcoin will be like a year from now, let alone 20 years from now. Other cryptos are even less predictable, so you might as well not even try to use those as a way to get involved.
It all, and I mean all, depends on your confidence. It's not up to us to determine what you'll get.

what does a hard fork have to do with anything that OP asks!
for example coins belonging to Satoshi are still not touched, if we assume they are saved in a cold storage, there was already one hard fork and the coins are still there in the cold storage and spendable!

and a hardware wallet does not sound like a good choice for a long term storage like 20 years that OP is asking. the data loss is a serious possibility with digital storage when it is not connected to a power source. and firmware updates of some hardware wallets is scary and hard.

Sooner or later everyone will be exposed to the crypto world whether they like it or not. I'm more concerned about you forgetting about your cold storage wallet or losing it when storing it for such a long period of time. You would need to take some really good precautions to avoid it.

It's 100% safe as long as you will keep it safe. Since it will be untouchable then no way it can be on danger unless the problem will be intentional.

Also up to you if you want to stay not updated in the cryptoworld for 20 years. It will just landed on two possible outputs, bitcoin is fail after 20 years or bitcoin's price worth is enough to covered your retirement and can give you a rich status.
