In 2019, Tom Lee suggested on a CNBC interview program that investors allocate 1%-2% of their holdings to Bitcoin, but the host of the CNBC program at the time called this view "too crazy."

During the show, CNBC host Becky spoke with Tom Lee to discuss whether Bitcoin is "seriously undervalued" and whether it should be invested in.

Tom Lee stated that allocating 1%-2% of assets to Bitcoin is a wise move for most investors, and even ordinary retail investors or retirement savers can afford this type of "small bet." He emphasized that Bitcoin's annual gains are typically concentrated in its strongest 10 days. If these 10 days are missed, the annual return could plummet by 25%, making "long-term holding" a key strategy.

At that time, the price of Bitcoin was still $5,000. Now it seems that this "small bet" may be the best investment opportunity.
