Wow, I just saw that today's market is so complicated! Bitcoin and Ethereum both dropped significantly, seems like the People's Bank of China issued some document? And the US stock market isn't doing well either. It's the first time I've heard of the term "Gas fee," I don't know what it means. I saw a DeFi project was hacked, is it that scary? 😱 The crypto market really feels unstable. Also, there's the risk of Tether's reserves being insufficient—how does that affect us ordinary investors? There are so many professional terms I don't understand; I really wish someone could explain them to me. But seeing all these new things makes me a bit excited; it feels like I'm learning something new every day! 🤓 Does anyone have any beginner tips?
