In this bull market, if you want to make money, there is one principle that is particularly important: do not invest your emotions in altcoins. Apart from Bitcoin, the upward logic of other cryptocurrencies is very weak, more driven by trends or emotions. Once the market turns, they are often the first to decline.

The recent rise of Ethereum is actually not closely related to its own on-chain development. It is more because Bitcoin has risen significantly, and some funds start to look for a 'second choice', with Ethereum naturally becoming the first choice as the second largest market cap coin. It can be understood that Ethereum is a 'magnifying glass' for Bitcoin's trends, rather than an independent trend.

The rhythm of the entire market is fast, and capital flow is key. Following the flow of capital and grasping the rotation rhythm is more effective than sticking to a particular coin. Especially when Bitcoin experiences a correction, some strong coins may have short-term rebound opportunities, making short-term operations more advantageous.

In the current market environment, the opportunities for retail investors to hold on long-term and rely on 'faith' to double their investments are decreasing. While fundamentals and positive news are important, they are not enough to support long-term holding of a cryptocurrency. The market changes too quickly, and the risks are increasing.

In the cryptocurrency world, it ultimately comes down to profiting from volatility, information asymmetry, and cognitive dividends. For large funds, I would take BTC; this should be the default for everyone. My choice of BTC is not out of faith in it, but because it has liquidity, chip distribution, and risk-hedging value. Most importantly, it is a product controlled by others. Large countries are hoarding it, institutions are investing in it, and ETFs are absorbing it. For coins of this level, you do not need to think too much; its direction is already rooted in political games.
