Trezor or Paper Wallet?

[StockBet.com]

When it comes time to spend your paper wallet, you need to load that private key into some kind of device (eg. Computer, phone, table) and sign a transaction. At this stage, you have to worry about the security of that system. Is it compromised? Does it have a hacked/buggy RNG? Will it leak your keys through a side channel? The trezor does the signing securely on the device. The keys never leave it and never need to be loaded onto another device.

With Electrum, you run it on an offline computer or bootable USB and you sign the transaction there.  Then you take the transaction to the online computer and broadcast the transaction.  The private key never leaves your offline computer.

why would the TREZOR be so expensive? it not like it has NASA level hardware (neither software)

This implies that you have to trust that the manufacturer doesn't have any rogue employees.

Much like you have to trust your OS maker doesn't have any rogue employees... or Intel/AMD... or the hard drive manufacturer... or the USB manufacturer... or the WiFi chipset manufacturer... or the RAM manufacturer... or the Ethernet manufacturer... or the Router/Modem manufacturer... or the <insert every other link in the chain>

Trezor do their best, and you can verify the publicly viewable code is the one on your device...: https://github.com/trezor/trezor-mcu/blob/master/README.md#how-to-get-fingerprint-of-firmware-signed-and-distributed-by-satoshilabs

With Electrum, you run it on an offline computer or bootable USB and you sign the transaction there.  Then you take the transaction to the online computer and broadcast the transaction.  The private key never leaves your offline computer.

And what makes you think that a rogue version of Electrum wouldn't encode your private key in the OP_RETURN section of your transaction prior to signing it? What guarantee do you have that the version of Electrum you downloaded is the same as the code on Github?


You'll NEVER find a 100% secure solution... there are ALWAYS attack vectors... especially when humans are involved.

if you dont wanna spend extra money,  paper wallet is the best option.

[steamon]

I would go for an encrypted cloud storage and a written private keys on paper. Why don't I like a Trezor its electronics if it breaks everything is gone and paper wallet what if your house burns down you lose everything? There are ways to avoid it with a fire safe for example. Every has their personal choice. I am hoping that most wallets in the future will have f2a authentication added so you can't lose any crypto even if they can guess something. Yea it won't stop a private key hacker that's why I say write that on paper. If then your house burns you can still log in on new pc with 2fa and get the private key out again.

For long period of hodling, i think paper wallet is best, but trezor is better if you use your coins everyday.

[Cerbera]

You could also consider the Ledger Nano S. I believe that it will be supporting NEO in the near future.

[kolloh]

Hardware wallets like the Trezor or Ledger Nano S are much more convenient than paper wallets if you intend to send your coins at all. It is annoying to create new paper wallets everytime you spend coins. For long term storage where you aren't spending the coins, paper wallets work well though and don't cost anything to use.

ONE argument for Trezor vs paper wallet for the long term is what happens if BTC goes to 500k. Suppose you were the lucky guy that had an old paper wallet with 20BTC.....

To use them, you must load the entire sum into some computer and at that moment it is exposed to possible compromise. Because of the "NO CHANGE" property of paper wallets, the entire sum must be swept or imported into a wallet.

A Trezor with 20BTC in that situation, you could pull out say 0.01BTC and only that would be exposed to possible compromise.

I think it would be wise with the Trezor to verify the operation of the HD word sequence restore in one or another wallet, say the Electrum, then to save a copy of that particular program on a flash drive and put it with the Trezor in a safe. You proved it worked with that one wallet, not with any or some wallet that might exist in ten years.

Can Trevor be used for other crypto currencies or is only for BTC?

Can Trevor be used for other crypto currencies or is only for BTC?

Hmmm... it seems that neither Google nor the Trezor website are down... so I'm not sure why you could not find this information

[ferumflex]

I would select trezor and paper wallet but it in a safe place. In case I lost hardware wallet and my memory

[Kumic]

If we talk about a larger value or let's say more than 10BTC, I think that we should use more than one safe storage. Divide your coins and put them into 3 Trezor and 3 Paper Wallets, leave some on Ledger too. Buy one PC just for paper wallet and other transactions, make it safe, don't watch porn on that pc bro lol. Invest in your own security, that's a good investment.

[Backupnime]

i prefer in Trezor better than paper wallet.

[Rahip]

What is your preference? Ledger or trezor ?

[nicosey]

Ledger is easier to use then Ledger.  Ledger more secure.

[smokeydog]

i prefer paper wallet. because trezor is hardware too and it can be hacked one day.

How can it be hacked if it is off-line and in safe storage?

4) What are the pros and cons of using a Trezor wallet?

With the trezor hardware wallet, the device is the two-factor authentication, allowing owners to unlock their passwords without third-parties, applications, sms or email. Rather than relying on the master password scenario, the user simply “unlocks” the device with their pin and keeps passwords safe from keyloggers and physical attacks. Getting compromised is virtually impossible. This is due to the trezor platform securing each password entry on a “one-by-one basis with a unique encryption key,” which is derived directly from the trezor device.

[hakuna]

I own a Ledger Nano and it is one of the best buys of the year.

I think the pros are the same than the Trezor.
- you can have multiple wallets (BTC, ETH, etc) without messing with private keys
- you can "transfer" your wallets on another device, if lost or stolen, using the sequence of words provided to you
- the signature of the message is done on the device, hence it is more secure

Then I think the choice is also linked to whether you are an organized person, or not. Having all the wallet in a unique place could save a lot of time, if you are a messy person.

[miguelmorales85]

I would recommend trezor but the sheet with your recovery word should be divided into sections and keep them under lock in different sites.

Paper wallet from my point of view is too risky but there is no safer way to protect against hackers. 

In the end you must manage risk and spread it into several kind of holding methods.


PS: if you don't have your private keys those bitcoins aren't yours!

good luck
