Don't forget that electrum still needs an internet connection to connect to the blockchain. Every wallet needs to, sooner or later. Although you may have the electrum installation file on your USB, it needs to grab a legit copy of the blockchain to sync your transactions and all the essentials
.
I think you also might have misunderstood the concept of a "cold wallet". When you make a cold wallet, you still have to be synced to the blockchain. However, once the cold wallet is made, it is literally "cold" without any need for a connection to the blockchain until it is used for a withdrawal.
I hoped my answer helped. My apologies if it doesn't quite make sense.
What?
https://electrum.org/tutorials.html#offline-mpkOf course you can make a wallet offline. Creating a wallet has nothing to do with the blockchain. You dont even need the blockchain to make a transaction. Chances are its not going to be valid if you dont know how much you can spend, but you can still create it.
Hello!
I've read a lot of tutorials but I must have missed something because I cant find a way to install electrum on a computer without an internet connection. I have electrum on a usb file along with linux mint. I boot on linux mint but then what shall I do?
Why do people use the internet connection to install electrum on the livecd ? doesnt that defeat the purpose of the coldwallet?
please hlep
Did you download the standalone version*?
I just tried it at and it worked fine*. I even go the "you are offline" warning. Not sure if thats the message you get and just interpret it differently.
*Edit: just realized that you are on a linux machine.
The problem is that you need to install electrum first and that must currently happen online. see also here:
https://bitcointalk.org/index.php?topic=416881.0The security part is that you take that version of Linux (in the guide its ubuntu, but mint is similar) to an offline PC, create your key there, so the key has never been online.
