Hello, I have a little misunderstanding.
When I download Bitcoin-qt, I launch it, sync it, and I have a wallet.
I can generate multiple addresses to which people might send money to.
So, I have a wallet A, and generate 3 addresses. Address Aa Ab and Ac.
3 persons, send me 1 BTC each (each person to assigned address).
If I got it right, those addresses are not connected in any way (except they all lead to my wallet), so those people cant reveal my current balance of 3 BTC. (right?)
I have 1 BTC on adress Aa, 1 BTC on Ab and 1 BTC on Ac.
I have 3 BTC in total.
But now comes the catch. When I decide to send 2 BTC to new guy (number 4), where will those BTCs come from? My wallet says I have 3 BTC, so I can definitely send 2 BTC.
But I dont have 2 BTC on single adress, so how can I send 2 BTC in a single transaction to another adress?
If BTC are bound to receiving addresses, I should not be able to send 2 BTC, only 1 BTC two times, each time from one of those addresses.
If they are bound to wallet, how do those people cant see that my current balance is 3 BTC?
I am confused, sorry if this seems stupid. Any explanation helps
If you have three Bitcoins on three different addresses in your wallet, no, the 3 people who sent you 1 bitcoin each will not know about each others' transactions.
If you try to send 2 Bitcoins to a fourth person, he will see that his two Bitcoins came from two different addresses. I do not know how the Bitcoin client determines which of the two addresses it will use.
