Yesterday we talked about ETH, today we're talking about SOL. If ETH is the king of shanzhai, then SOL can be called the king of memes. ETH and SOL, as the two mainstream public chains, each have different technical characteristics and ecological advantages. Ethereum's REV (Real Economic Value) mainly comes from practical applications such as DeFi and stablecoin transfers, with a more robust economic foundation. Solana's REV is highly dependent on meme trading, which has zero sum game nature and is difficult to sustain its high valuation (SOL's FDV/REV ratio reaches 45:1). When the meme market was sluggish, SOL prices quickly fell from a high of 295U to the current 133U in just February. In contrast, Ethereum's valuation logic focuses more on long-term ecological development rather than short-term speculation. The core advantages of Ethereum lie in its mature technical architecture, decentralized governance, compliance status, and robust ecosystem, making it suitable for long-term investment and institutional configuration. Although Solana excels in performance and short-term speculative heat, it needs to address issues of stability, decentralization, and economic sustainability. When the golden dog on the chain prospers, SOL will become the most handsome guy, but currently the popularity of BNB chain continues to rise, and with the devastating decline of memes, SOL's drop below 100U may only be a matter of time, relying solely on memes for support is not a long-term solution.
