$BTC 🪙 BTC is the first asset I researched when entering the crypto market. Despite its strong volatility, BTC always plays a central role in the entire market. Most of the investment or trading strategies I build revolve around observing BTC's trends. When BTC is stable, altcoins often have a better chance to grow. Additionally, I also use BTC as a conversion unit to assess portfolio performance. For me, BTC remains the most important foundation for learning and developing long-term strategies.
