If I were to engage in the secondary market, I would choose ETH, SOL, and OKB, as they offer the best value for money.
To play in the primary market, one must select projects with low buzz and few promotions. If it's too lively, it’s either already in the later stages of a major uptrend or lacks momentum. I believe that the primary market should mainly focus on the SOL chain, while other chains can be explored casually. You see, even Kanye knows to launch a coin on SOL; now we just need an event to ignite the market, bringing existing funds back to SOL, and with the right monetary policy, the profit effect will follow.
SOL has now submitted an ETF application, with a market cap of 110 billion USD, which is still very low.
