I prefer to get rid of change, one way is using an instant exchanger (on Tor, of course) to convert it to Bitcoin Lightning Network, or Monero, or plan your payments such that you can pay for multiple services at once.
Which instant exchanger is reliable for this ? could u suggest one ?
what is the difference to cut it out the change from electrum witrh freezing or additional steps to avoid change balance like exchanging into lighting or Monero from an anomiymity standpoint.
is always safer to exchange bitcoin into another crypto for avoiding changing. ?
best regards
Fixedfloat seems to be good for swapping between coins, including Lightning Network.
Privacytools.io lists a bunch of private crypto exchanges and instant swappers that you can also try out, and some of here also support LN.
I would put the change by itself in its own LN channel and then you can use it for such things as micropayments. Do not mix your change with your other UTXOs.
