I have copied electrum.dat to USB but I'm not sure if that is what you mean.?
Offline ?
I don't want to be pain but sadly I'm a bit clueless
two things you need to back uo
1. seed: http://docs.electrum.org/en/latest/faq.html#what-is-the-seed
2. wallet file: http://docs.electrum.org/en/latest/faq.html#where-is-my-wallet-file-located
you can and should write down the seed on piece of paper.
Thank you very much for your help
be careful when upgrading. make sure to back up your wallet file and seed first and also read this link: http://docs.electrum.org/en/latest/faq.html#how-to-upgrade-electrum
then upgrade. the wallet has changed since version 1.x and you may encounter some troubles. so it is best to have these 2 backups just in case.
I bought BTC in 2013 and guy said to me to use Electrum to store them.
So I downloaded Electrum and didn't fidle with it since.
I'm mining ALT coins and all that stuff but I have stopped doing anything BTC related since Habannero boards stopped being profitable.
I have seed (random words) stored on USB drive.
I have Electrum.dat on the same USB drive.
Is this good enough backup before updating ?
What issues can I encounter ?
I'm going to read that article about upgrading.
I really appreciate your help
