$BTC Bitcoin (BTC) has always been the leading cryptocurrency in the market, serving as "digital gold" in the crypto world. Despite many periods of strong volatility, BTC has proven the strength and trust of the community through long-term growth cycles. With a limited supply of 21 million BTC and regular halving cycles, the value of BTC is becoming increasingly scarce. Many investors choose the DCA (dollar-cost averaging) strategy to accumulate BTC in the long term, instead of trying to "catch the bottom." Holding BTC not only offers the opportunity for profit but also serves as a hedge against inflation and global economic risks. In the future, BTC may play an important role as a global digital reserve asset.
