📊 Mainstream coin valuation and volatility quick scan

**Bitcoin(BTC)**: Slightly overbought, deviating from the mean by 0.98 standard deviations. Current average price reaches $92089, bullish signals are clear🟢, but high volatility risk should be noted. Large oscillation amplitude, short-term profit-taking may exist.

**Ethereum(ETH)**: In a mild overbought zone, with a standard deviation of only 0.74, relatively moderate. Average price around $3165, bulls are dominant🟢, volatility is at a medium level, and the trend is relatively stable.

**Solana(SOL)**: Valuation at a fair price level, with a standard deviation of 0.35 indicating relatively balanced pricing, no obvious overvaluation or undervaluation pressure. The market's valuation logic for it is temporarily more rational.

Overall, BTC and ETH show a synchronized upward trend, but BTC's overheating degree is relatively higher, requiring attention to correction risks. SOL is relatively stable and can be used as a risk hedge.
