Hi there and thanks for reading.

As far as I understood there have to be 2 addresses for each transaction.
On for the sender and one for the recipient... is this right ?  

I wonder because when I take a look at the transactions there is just a single address for each transaction.
If I send BTC the recipients address, if I get BTC (one of) my own addresses.

So where can I see the other address ?

When I send BTC to an address, what will my address be for the recipient ?

Thanks ... Sorry...
