Here is a three-tier structure template for an investment system:
1) Cognitive Level (Understanding how the market operates)
Macro Logic: Inflation, Interest Rate Hikes, Risk Appetite
On-chain Structure: Mainstream Coin Behavior, Chain Fee Changes, TVL Trends
Market Roles: Market Makers, Whales, Retail Investor Behavior
2) Tool Level (What you use to judge)
Technical Indicators: Trends + Volume + Divergence
Data Platforms: Arkham, Lookonchain, Santiment, Dexscreener
Analytical Methods: Sentiment Cycles, Chip Distribution, Capital Flow
3) Strategy Level (How you operate)
Dollar-Cost Averaging? Trends? Storytelling? Arbitrage? Contract Following?
Establish your own entry logic, take profit and stop-loss, risk control boundaries
These elements require long-term reading + practice + review to fully grasp.
