I often read that the lightning network has good sender privacy but since public nodes can be contacted and possibly pressured to share the details of their part of the transaction, a motivated attacker could backtrack the transaction from the receiver to the source utxo, right?
Does having a longer path increase your privacy lowering the risk of the nodes colluding to reveal the originating utxo?
Is there a tool where you can specify a minimum number of hops for a transaction? So far in my experience my node will always pick the shortest path (usually 2-3 hops) and I never found a wallet that lets me chose longer paths.
