Lately, I've been taking the elevator back and forth between the mainnet and L2, and it really feels like there's a choice between "saving money" and "peace of mind"—you can only pick one... My current compromise is: for small daily transactions and frequent operations, I use L2 since it's fast anyway; but when it comes to moving large amounts, switching to a cold wallet, or authorizations, I grit my teeth and go on the mainnet to pay the tuition fee, just to be safe. As for what "signal" I look at? It's not a specific indicator chart, but whether my hand trembles when I open my wallet—that is, if I hesitate because gas fees are too high, then chances are this operation isn't really necessary. Also, recently there's been talk about social mining and fan tokens—basically, attention as a mining machine. I enjoy watching the excitement but don't really want to participate; the hype is hype, but transaction fees are real money... As for leverage, don't even get me started—overloading the elevator could really cause it to fall.
