I once had high hopes for Ethereum (ETH), believing that relying solely on Bitcoin (BTC) as a decentralized currency was far from enough. The decentralized financial system (DeFi) was the milestone progress that changed human society. I have a dream. I aspire to not only achieve efficient and low-cost transfers in DeFi, but also break free from the exploitation of large banks, regulatory constraints, and global tax pressures, thus realizing the sacred and inviolable ideal of fairness in private property. I even imagine that any company can issue stocks on Ethereum without bribing the China Securities Regulatory Commission (excluding China); People can achieve P2P lending, mortgage financing, and wealth management through Ethereum, completely reshaping the financial landscape. However, when I truly immersed myself in the DeFi practice of Ethereum, I realized that the high transaction fees made ordinary retail investors hesitate - Ethereum has become a "noble chain". The teams that have spent ten years in the cold window and devoted themselves to developing DeFi projects cannot sustain themselves solely with the support of venture capital (VC). In the early days, DeFi applications on Ethereum were mostly driven by emotions, and project developers did not even have a clear profit model in mind. The equity tokens (used for voting) that were reluctantly issued later also struggled to support long-term development. Although emotions may be beautiful, they cannot last long. DeFi's ideals are gradually shattered in the face of high costs and security vulnerabilities, making it inevitable for DeFi theft incidents to continue. After 2021, I completely withdrew from DeFi investments. I gradually understand that Ethereum, as a financial platform, should maintain low costs. Especially after switching to PoS (Proof of Stake) mechanism, it makes no sense for ETH prices to easily reach thousands of dollars. A reasonable ETH price should be in the double digits, only then can it truly support the popularization and development of a decentralized financial system. Recently, ETH prices have risen, but this is just a common herd behavior, and short-term speculation will eventually return to value. From ancient times to the present, both domestically and internationally, there is no exception. Those who expect ETH to rise to $10000 may have never engaged in financial practice on Ethereum, and may not even have experienced simple transfers or Uniswap transactions. Nowadays, Wall Street's vision for Ethereum is exactly the same as my aspirations in 2019. However, these financial giants have never actually used Ethereum for transfers, let alone participated in DeFi. After experiencing it firsthand, they may also feel the same disappointment and desolation.
