A crypto trader outlined a portfolio strategy centered on concentrating 80% of holdings in three to four coins for mid- to long-term positions, with predefined invalidation levels. The approach is intended to support closer tracking of each asset’s fundamentals and price action. The remaining 20% would be allocated to more speculative, active trades, while risk management would be used to limit downside. The trader also plans to keep stablecoins available for potential opportunities and avoid excessive trading between setups.
