The last time I downloaded Atomic wallet, it gives only one address, mayne it will change it once a transaction is made (I thought that) but I did not used it to make any transaction. Any wallet that do not change address are not recommendable if not changing address. You can not use coin control on Atomic wallet, it is close source wallet. Atomic wallet is never a recommendable wallet.

For privacy, the best is to run your own node like using or run your own [url=https://github.com/spesmilo/electrumx/blob/master/docs/HOWTO.rst]Electrum server. with Tor.

But for light client wallet (like the atomic you mentioned, but not recommendable), you can use Electrum wallet, but using Tor with it (not IP address) for anonymity.

This is accepted, there is no bank transaction hidden online to as it can easily be tracked by the banks, but also most people that are using bitcoin nowadays are using it in a way privacy or anonymity is not possible, they make use of IP address, light client wallet, using a kind of light client wallet that only gives them just an address, they track transaction using blockchain explorer with their IP and sort of no privacy means of using bitcoin. Many of them are using centralized exchanges that nearly all of them are continuously demanding for KYC. The fact is that some people are using bitcoin in a way privacy and anonymity is never possible. But bitcoin can still just be used in way privacy is possible just as mocacinno already lost about it.
