Also, if I make different withdrawals do they come from the same address or will a brand new address be used for every transaction?
We wouldn't be able to send from an address that hasn't received funds (i.e. doesn't have any outputs associated with it), but we don't consolidate deposits into a single address, if that's what you mean.
Thanks for your prompt answer.
Actually what I wanted to know is : if I will make several withdrawals from my account will they all be sent from the same address or will the sending address be different each time? And if it's the second case could these addresses be linked each other in some way with chain analysis tools?
Maybe your sentence I quoted already answers my questions but my limited technical knowledge prevents me from understanding it properly.
