Is storing my crypto on a cold wallet totally safe, or do I need to take additional security measures?

What are the remaining risks if there are any?

They are only a Wallet Paper generator. where generate addresses form one pair of seeds.

>> No.16526482

Use a hardware wallet, it's the most secure storage method since it prevents your private key from ever touching anything. Hide your backup seed phrase in a good spot. Do not use a PIN you have used before. If you successfully followed all these steps you are now at the highest reasonable level of security for one person.

>> No.16526499

If your curious, security beyond this would require a multi-signature solution to move coins as well as a way to verify identity with the other party or parties.

>> No.16526511

They are safe only if you use them as a cold storage. (keep safe the seeds words, the ledger has only 5 years life span but with the seeds you can buy another and you are good.)

Do you need to enter these seed words every time you want to access your cold storage wallet, or just when you are tranfering to a new one?

For the Ledger Nano S you enter a 4+ digit PIN to unlock it. IIRC it will wipe itself completely after 3 incorrect tries so then you would have to enter your seed again (which is done using the Ledger Nano S, not your computer - meaning you could use your Ledger on a malware infested computer or a stranger's computer without any worry of someone stealing your seed)

>Also there is no way for a hacker to get my coins as long as they are in a cold storage wallet, right? They would need to physically steal the wallet from me, right?
yeah what this anon says >>16526764
In the case that your cryptosteel was stolen the intruder would not need the PIN as the PIN is only for the Ledger Nano S's security. The intruder may be profoundly retarded in which case they would fail to use the cryptosteel as it stores only the first 4 letters of each word in your mnemonic key as each word in the entire set has a unique first 4 letters. As an extra level of security you could store the cryptosteel in a safe but even that could be breached potentially.

use a paper wallet for cold storage you niglet!
hardware wallets are for actual use and that metal plate bullshit is not good for anything.

>> No.16528203

why would you write down your seed in plain text and only store it at one place?
secure redundancy dictates you use multiple sites many copies of which no site alone compromised can lead to a loss of wealth.
either use password encrypted paper wallets, or use shamirs on your seed.

i however do not recommend seed based hierarchic deterministic wallets for future use (ie cold store for generational wealth) because the quantum resistance can become an issue any year and if one private key of a hierarchy - even if no longer used - is compromised they all are.

crypto steel is the most retarded shit i ever saw.

>> No.16528250

this guy actually understands this shit.
however it's worth mention that the pin is snake oil security. it's fairly straightforward do take secure chips out of the resin and or grind them down and read the memory content with an electron beam probe. at which point the pin is absolutely worthless.

trezor has a better security model with the capability to use a strong passphrase that is worth something and decoy wallet. however it's not side channel hardened like nano.

in the end they are trinkets not advisable to use as col store but to use as a hot spend wallet storing no more than your monthly expenses.

no you plug them in when you use them. the point of the hardware wallets is they have a very narrow protocol interface with a potentially compromised system. of which they keep the private keys off of.

shouldnt rely solely on any form of local electronic storage, its not a matter of whether its safe from a security standpoint - its about what happens if the hardware fails.

no it's not a good idea to use a hardware wallet for cold store at best it does nothing to improve your security at worst it's a physical attack vector.

secure redundancy! have many copies of your secrets at many locations but none of them should give access to your funds in itself!

one example of effortless security: put your pks in a password safe app use a good derivation algo with high iteration and a good strong passphrase. upload the shit to cloud keep local copies in a safe and on your person.

that's secure redundancy.

or use password protected hardware wallets have multiple copies at multiple locations, but use shamirs to break up your password and store them in a way that the attacker would need to access a lot of places simultaneously to get your shit on the other hand making inheritance a smooth sail. this includes a safety deposit box or a lawyer (you can put a piece or two in your will). and handing out pieces to relatives and safeguarding others. that's fucking secure redundancy. even if a site is obliterated you lose nothing.

Download Coinbase wallet or Trust wallet, generate a wallet, transfer funds, and never ever jailbreak it. Done.

also bip-38 is pretty much a bitcoin standard. it's not some proprietary bullshit. it has a very robust implementation that works on an air-gapped computer booted from a live cd.

you can obviously try decrypting your keys and checking them before sending any funds to them.

i mean it's not like you can make a signature or assemble a tx without a software either. you need tools to use bitcoin. some wallets can import them right now, others will be able to import them in a few years. in fact you will be able to directly swipe your bip-38 wallet into your exchange account by 2023 imo.

Credit/debit card all over again, but just with new brainlets.
It doesn't fucking matter if you print your "paper wallet" or this nanou ledger usb type thing.
All your btc is always on blockchain.
If someone can break your security measures they can take your btc and move them.
It doesn't matter if you print your key words for password or other shenanigans, if someone breaks your hash, they can move your btc, because BTC is always on a chain.
You can't convert btc to any other form, be it paper, usb or water.
What you do with nanouledger usb type thing is, you essentially, in simple words, you put your debit card into another debit card. Sound stupid right? Thats how it is, your btc wallet is access to btc on chain, but you put your access into tonanouledger usb type thing and make another wallet on top, while btc is still on chain.
If NSA can generate your hash by accident they can take your btc and move them, no goddman nanouledger usb type thing will help ya. BTC is always on chain and it can be moved no matter your infinite security layers.

It's important to differentiate between the exchange's security, and your own security.
Sure, the exchange could be secure, but it doesn't take more than a weak password and SMS 2FA to breach it.

>> No.16531823

you have to understand that every private key (2^256) is already on the blockchain. The hardware wallet is only the tool to gain access to the coins by randomly creating a key, or importing a known key with holdings in it.

So you can randomly create a key on the ledger and put crypto on it. Then throw the ledger away, buy a new one, and import your known key into it again.

All it's storing is the key, that's what a wallet is, a key, nothing else. Bitcoins actually don't exist, the public ledger that is hosted concurrently accross all bitcoin nodes just keep track of imaginary balances connected to bitcoin addresses. Your cold wallet holds the key to a certain address. It's the safest method, as it is impossible for somebody to get your key unless they physically get your usb.
