• Liquidity (30%): 24h volume of $500M or more scores 0 risk points, under $50,000 scores 100.
• Volatility (25%): average daily price swing over 7 days; under 2% scores 0, 15% or more scores 100. Hours where the price jumps more than 40% and immediately comes back (usually a bad price on one exchange) are not counted.
• Exchanges listed (15%): counted on the 8 core exchanges (Binance, OKX, Bybit, KuCoin, Gate, Bitget, HTX, MEXC): listed on all 8 scores 0, on just 1 scores 100.
• Cross-exchange spread (15%): the more prices differ across exchanges, the thinner the market; 2% or more scores 100.
• Price history length (15%): 3+ years of price history scores 0, under 30 days scores 100.
• Security incident (adds 10 points): the project was hacked for $1 million or more in the past 12 months (DefiLlama data).

This score mainly measures trading risk (how easy it is to buy and sell, how stable the price is), plus a penalty when the project was recently hacked. It does not assess the team or code quality, and not investment advice. A low score does not mean a coin is safe.
