The key points that haven't been mentioned: AI is popular but chaotic with many pitfalls, and its certainty is not strong. The market value of old AIs is very high with low cost-effectiveness. New public chains are acceptable. Additionally, the market value of Layer 2 is low, but its cost-effectiveness and certainty are higher than many altcoins. After all, 2025 is the year of Ethereum, and the rise of altcoins still depends on Ethereum. The Prague upgrade is beneficial for Ethereum Layer 2. Moreover, the financing scale of Layer 2 has exceeded 10 billion; some low market value ones can be bought. As for other hot coins, it's better to skip them. In 2025, the focus is on stability. Everyone knows that the bull market will end.
