I do (run a node) but I still figure watch only solutions like sparrow or nunchuck (esp nunchuck if u use a phone app) are weak links to identifying/doxing utxo’s even if the private keys are stored off line…am I wrong on this?

Except for occasional utxo management I only transact with lightning and even then it’s primarily for orange pilling frenz (giving small amounts) and then to pay said frenz when I owe them for something like a meal if they prefer btc to cash (and they almost always do).
