short:
Is a wallet created on an offline computer with Electrum unique?
longer version:
I like Electrum and have used it for quite some time now. Now I wanna do this:
http://docs.electrum.org/en/latest/coldstorage.htmlI did research a little (just a little sorry...) but couldn't find the answers to the questions further down. Maybe one of the pros here can answer them easily. Thanks.
Electrum can't find out if the Address it creates is already in use since I plan to never plug this computer to the internet again after downloading Electrum. So....
1. Will it for sure create a new address?
2. Are all addresses created unique? For sure?
3. Do I have to hurry to put BTC into the offline created address, before anyone else gets it in a hot wallet?
