Recently came across a bunch of testnet "point strategies," looking like practice questions, and as I kept doing them, they turned into expected returns... When my mindset started to wobble, I began adding more time, more accounts, more scripts, and in the end, I was just being led by it.

My stop-loss is pretty simple: set a limit for myself, like spending no more than 30 minutes a day, and if there's no progress in three days, stop; if I need to install unfamiliar plugins or click on strange links, I just give up—prefer to miss out.
Especially lately, phishing links are rampant, hardware wallets are out of stock, and if I risk my main wallet just for some points, just thinking about it isn't worth it.
Anyway, I treat it as practice, and once I start to feel anxious, I call it a day.
