According to Compounding Quality on Twitter, the 100-Age Rule suggests that investors should subtract their age from 100 to determine the percentage of their portfolio allocated to equities, with the remainder in safer assets. For crypto traders, this rule offers a concrete framework to adjust risk exposure as market volatility increases or as personal risk tolerance changes. Applying this rule can help traders manage downside risks in both crypto and traditional markets, especially during periods of heightened uncertainty (source: @QCompounding, June 8, 2025).
