Yes. If block goes away you can sweep funds to a different wallet using the emergency exit kit- however I have not had a chance to test this myself yet. I have a bitkey that so far works great for sending, receiving and holding. But will need to test the emergency recovery before I can fully endorse. So far my experience with it is great. But not utxo management or coin control other than a button in the app that consolidates UTXOs. Would be nice if they added some advanced coin control features to the app in the future but not sure if that is in the pipeline or not
