Crypto Radar

Screening Filters

1. Market Cap ≥ 5,000,000,000 (≥ $5B)

   • Purpose: Focus on large, established cryptocurrencies.
   • Rationale:
     • When someone asks for an “analysis or overview of the cryptocurrency market,” you typically want to look at the major assets that shape overall market behavior, not tiny speculative tokens.
     • A $5B+ market cap threshold limits the universe to top-tier coins (e.g., BTC, ETH, and other large-cap alts), which:
       • Have meaningful adoption and ecosystem activity.
       • Are more likely to influence and reflect broad market trends.
     • This makes the resulting set of cryptos more representative for a market-level overview.

2. 24h Turnover (Trading Volume) ≥ 100,000,000 (≥ $100M)

   • Purpose: Ensure only highly liquid, actively traded cryptocurrencies are included.
   • Rationale:
     • For a market overview, you want assets where price and volume data reliably reflect real investor activity.
     • High 24h turnover:
       • Filters out illiquid projects with sporadic trading and unreliable price signals.
       • Focuses on coins where institutional and retail participants are both active.
     • This helps any analysis be grounded in assets that genuinely matter to current market flows.

3. Correlation with BTC ≥ 0.6

   • Purpose: Select cryptocurrencies whose price movements are meaningfully tied to Bitcoin.
   • Rationale:
     • Bitcoin is the primary benchmark and risk-on/off barometer for the crypto market.
     • Many large cryptos move broadly in tandem with BTC—especially in risk cycles (bull/bear markets, liquidity shifts).
     • A correlation threshold of 0.6+:
       • Filters to coins that are statistically aligned with the broader market cycle, not isolated outliers.
       • Makes them more useful for explaining “the crypto market” behavior when BTC rises or falls.
     • This is appropriate for a high-level “market overview” rather than niche, uncorrelated projects.

4. is_trending = True

   • Purpose: Emphasize cryptocurrencies currently attracting attention and momentum.
   • Rationale:
     • An “overview of the cryptocurrency market” is more useful when it reflects what is important right now: themes, narratives, and coins that are driving current sentiment.
     • A trending flag typically captures assets with:
       • Elevated trading interest.
       • News flow, social/media attention, or notable price action.
     • Including this filter keeps the focus on parts of the market where current market dynamics are most visible.

Why Results Match the User’s Request

• The user wants an overview of the cryptocurrency market, not obscure or illiquid tokens.
  • Large market cap and high turnover filters ensure we’re looking at major, liquid assets that genuinely drive and reflect the market.
• Bitcoin is the anchor of the crypto ecosystem; by requiring a reasonable correlation with BTC, the screener focuses on coins whose movements are representative of the broader crypto cycle.
• The trending requirement ensures that the selected coins are not just large, but also currently influential in shaping market sentiment and narrative.

Together, these filters identify a set of large, liquid, BTC-linked, currently active cryptocurrencies that are well-suited as a basis for providing a meaningful, up-to-date analysis of the overall crypto market.
