thank you that was quite informative !...
But is there is a way to have a permanent receive address or change it WHEN I WANT TO ?...
What if i give my receive address to someone to send me BTC then it changes, will i get my BTC or it will be lost ?!?...
And is it impossible to restore access to my wallet if i loose the the wallet.dat file ?.. from what i learned about BTC the funds are stored in the BTC network not actually on the machine, so is there is a way to get it back or no ?...
thanks again,
Your wallet.dat holds all your addresses (and private keys). So, you can use every address as often as you like, but it is not recommended because this makes it easier to track you.
