Bitcoin has once again broken through the 70,000 mark, just a step away from its historical peak, but altcoins are still struggling halfway up the mountain or at the base. What is going on?

Bitcoin's strong performance is indeed impressive, but the fate of other altcoins is quite different.

Ethereum is still 46% away from its historical high, while Solana and BNB have declines of 30% and 16% respectively to recover.

Meanwhile, popular cryptocurrencies from the last bull market, such as Dogecoin, Shib, Cardano, ICP, Filecoin, and Polkadot, have seen catastrophic declines of up to 70% or even 90%. This makes one lament that it can really only be said to be a bull market for Bitcoin, while other altcoins are far from keeping pace.

The key reason for this is insufficient market liquidity. In a situation of low liquidity, it is difficult for capital to spread broadly, making a widespread bullish trend hard to achieve.

Therefore, although Bitcoin's growth is encouraging, other altcoins will likely need some time to catch up.

Moreover, historical experience shows that altcoins that can outperform Bitcoin are only a very small minority.

Of course, this does not mean that altcoins lack investment value. Led by Bitcoin, the entire cryptocurrency market is still full of opportunities and challenges.

As long as one can choose the right varieties and seize the timing, altcoins can also bring substantial returns.

In summary, Bitcoin's bull market momentum is currently strong, but other altcoins still need to be patient and wait.

However, this does not mean they lack investment value; with diligent exploration, one can always find opportunities that suit them.
