I only take one note: Don't just give unlimited contract authorization to save trouble; if you can revoke it easily, do so—just like locking the door before bed—otherwise, one day when you're busy mining social media or fan tokens with the "attention is mining" craze, and your attention drifts away, your wallet might be emptied by someone else "mining" it for you. I, who am always a bit slow, would rather click revoke a couple more times than risk it, even if it means sleeping a little less.
