4. Remember you have to generate different bitcoin address (offline wallet) everytime you want to store remaining bitcoin for future if you don't want to keep any of your private keys online.
I didn't understand one part for example:
I transfer from xapo to my offline wallet 1 bitcoin then i want to transfer from my offline wallet 0.5 bitcoins to " eric " so how does in blockchain its if my wallet offline?
I didn't understand that thing if I have an offline wallet how people will know about the transaction and know and how it will synchronized ? or does every time that I transfer money from
my offline wallet it updates its status about bitcoin status how much I left and everything?
thank you!
