Topic: Keeping your butts safe - page 3. (Read 4165 times)
i am using armory to keep it safe offline. in a way it's the best possible security in my opinion. but I don't keep all of them. I spend daily.
Do you think cold storage is essential?
It's not essential, Linux, encrypted wallet and daily backup on 2 remote locations is enough... There are details about, but it's enough.

AND I have paper copies in another location, split up so you need both parts to complete the key.
There's an idea I haven't heard before. I might just try that. Even though I assume your private keys are BIP encrypted .... splitting them in half and putting them in two different locations is a pretty sick idea.

BittBurger, you mean you have never heard of Armory's fragmented backup solution?
Fragmented backup halfway down
buy an old laptop.
format it.
install linux on it.
download, install and run electrum.
write on paper the 12 word seed electrum gives you.
memorize it and repeat it every day for a week.
destroy the paper.
keep the laptop powered down, never use it for anything except sending money with electrum.

It seems like to me that this really is the only way to be 99.99% safe.
That being said, I think that this is a huuuuuuge flaw with bitcoin.
Who really is going to go through all those steps?
In fact, not only would people not want too, I am pretty sure most people don't know how to format a computer and definitely don't know how to install Linux.
For Bitcoin to advance, we need a rock solid way to protect bitcoins that is soooooo safe and sooooo easy
non of those steps are particularly hard to do.
im sure people can learn how to press the format button.
my grandma could install Ubuntu Linux, there is nothing to it except clicking next a bunch of times and entering a username and password.
using facebook is harder than any of these things.
and for the effort you get to store your money in your own international bitcoin bank, that can't be robbed or frozen.

question, hope to get an answer, thanks.
say a keylogger is logging my actions, would a right click copy and paste or ctrl c & ctrl v, expose the key to the hacker?
ooh paranoia.. lol

Some keyloggers monitor the clipboard and other keyloggers also log mouse clicks.
Have you tried TREZOR?
I wonder if and how badUSB affects devices like trezor... The only thing i could find on their "security threats" page that is somehow related to badUSB attack vectors is this :
"Reflashing the TREZOR with evil firmware
Official TREZOR firmware is signed by the SatoshiLabs master key. Installing unofficial firmware on the TREZOR is possible, but doing so will wipe the device storage and TREZOR will show a warning every time it starts. Reprogramming the bootloader is impossible, because all TREZORs ship with their secure programming fuse blown."
If you have a fair amount of bitcoins is it stupid to keep them all on Bitcoin Core on a computer that's just about always online?
Even with a good password?
Do you think cold storage is essential?
I will bring them into two parts, one part of them adopt storage offline ,the other will be online for my often using . Even with a good password?
Do you think cold storage is essential?
I have two offline wallets that split my BTC between the two. If something happens to one, I don't lose them all.
I have my public addresses as 'watch only' so I can monitor the balances.
I have my private keys stamped into metal that won't melt if the house burned down.
AND I have paper copies in another location, split up so you need both parts to complete the key.
I'm HODLing long term, so I wanted to be safe.

Wow, I must say this is very secure. Did you stamped it into silver yourself or had someone else do it?

What if you lose your flash drive that has your private keys, or what if it gets too close to a magnet?
Is that really an issue? I have dozens of flash drives, two of them have been near some pretty powerful magnets and they don't show any signs of damage. I can still read from them, write to them, reformat them and even boot an Ubuntu installer from them with no problems. I'm honestly curious about this, I know magnets will cause trouble for any kind of magnetic media, but I've never personally had any problems with flash drives.

Then you've also eliminated one of the more popular choices (paper wallets) as a viable means of cold storage, unless you keep your paper wallets in a bank vault (even a "fire safe" will not always protect paper locked inside).
Metal foil, like 0.03mm stainless steel, is cheap. You can buy it on Ebay and write on it with anything, like a ball point pen. That makes indentations that stay. Then put the sheet of foil between two pieces of cardboard and put it in the safe.
A fire safe will not protect CDs, SD cards, hard drives, anything like electronics.
It MAY protect paper and things on paper.
The problem is the laser and inkjet characters on paper under temperatures of 200-400 F.
What if characters stuck to the back of the next sheet? Then you pull the papers out of the safe, try to separate them and the letters cannot be read.
Characters should be BIG for safe long term storage. The bigger the better. Say an inch high. Hand writing with a permanent marker could be better than using a laser printer.
Exactly the same issue exists if no fire, but with long term storage - 10-20 years. Do not trust little bitty characters. Do not put sheets of paper next to each other. Do not use both front and back of a sheet.
Look at the Archival storage industry. Don't reinvent the wheel, these people already know how to do this.

cold storage is a must imo.

The metal is a great idea! What kind of metal, and how deep are the stamps?
It's actually two 10oz silver bars. The reasoning behind it is that it's something you're going to want to be careful protecting anyway, and the melting point of silver is around 1700 degrees F and a typical house fire burns around 1200 degrees F... Plus it's kinda neat
The stamped letters and numbers were hit relatively hard to make sure if the silver was scratched by something, everything would stand a great chance of being legible.

There's an idea I haven't heard before. I might just try that. Even though I assume your private keys are BIP encrypted .... splitting them in half and putting them in two different locations is a pretty sick idea.

Offline armory, that's the way to go.
This and make sure to create backups of your keys, also don't put all your eggs in one basket. You might want to split your coins up over 2-4 wallets.
If you won't use your bitcoins for a while, it would be better to keep them in offline wallet.
Do you think cold storage is essential?
Under 10 BTC not really10+ BTC yes
What if BTC goes back to 1k per coin, does that change your opinion? I would imagine that many people who elect the cold storage option are looking to hold their BTC for a while in hopes that the price rises. I think that even if you have 1 BTC, it's important to secure it as best you can.
