R.W. McNeel's 1927 investment principles, which emphasize buying below intrinsic value and maintaining emotional discipline, remain relevant in the 2025 crypto market. These principles align with Warren Buffett's value investing philosophy and offer guidance amid the speculative fervor and behavioral biases prevalent in cryptocurrency trading. The recent surge in MMT token prices, driven by social media-induced FOMO and airdrop expectations, underscores the challenges of herd behavior and short-termism. McNeel's advice to focus on fundamentals over market sentiment is crucial for crypto investors evaluating utility, governance, and innovation. By adhering to these principles, investors can mitigate risks associated with cognitive biases, which often lead to significant losses during market corrections.
