On December 17, 2025, former Tsinghua University associate professor Hu Yilin discussed the strategy of dollar-cost averaging (DCA) Bitcoin investments on the Sea Talk podcast. Hu advised newcomers to adopt a "spare money investment" approach, cautioning against borrowing or going "all in" to avoid psychological stress and disruption to daily life. Hu emphasized viewing Bitcoin investments as a form of pension purchase, suggesting that funds typically allocated for regular savings or long-term funds be consistently invested in Bitcoin. This approach allows for continuous investment without the stress of constant market monitoring, promoting a stable and healthy lifestyle.
