It doesn't matter if it's a bull market or not; what matters is whether you can make money. Too many people lost money and got liquidated during a bull market. Don't think that just because a bull market is here, you can make a profit; that thought is too naive. During a bull market, most altcoins will indeed experience a surge, especially after Bitcoin rises first and attracts funds into the market. This phenomenon is quite common, primarily due to the "rotation effect" in the crypto market. Bitcoin usually takes the lead in a bull market, and its initial price increase attracts a lot of capital. As it enters consolidation or high-level adjustments, the funds start to flow into Ethereum and then gradually into smaller-cap altcoins, and even some obscure coins. However, not all altcoins can follow the explosive growth. Coins with small market capitalization and low liquidity may have significant price increases, but the risks are also very high. Some projects, if they don't have substantial value and are driven more by speculative sentiment, often see unsustainable price increases. Once market sentiment cools down, these coins can plummet severely. The bubbles in a bull market mostly come from such projects; they rise quickly but fall even faster.
