Today is the n-th day since I officially stepped into cryptocurrency trading. The platform I chose is Binance, and I picked a few 'big brother' cryptocurrencies: BTC, ETH, BNB, and the recently popular SOL. To be honest, the moment I opened the interface, I felt a bit nervous. Although I’ve heard that this market rises and falls like a roller coaster, when it comes to actually trading, even just clicking the buy button feels as serious as posting on social media for the first time.

I didn't expect to get rich overnight from this. Honestly, that kind of myth of explosive growth is exciting to watch, but believing in it will likely turn into a collection of lessons learned the hard way. My principle is just two words: 'preserve capital.' I don’t expect to double my investment in a day, but I hope that the coins I buy today won’t make me doubt my life tomorrow.

While watching the market, I discovered a little joy: the fluctuation rhythms of these coins actually have quite a character. BTC is like a steady big brother, not too chaotic; ETH is more active, like a middle-aged person working in tech; BNB is stable, a bit like Binance's favored child; as for SOL, it’s like a trendy youth, often making flashy fluctuations that make my hands itch while watching.
