  "standfirst": "The major-coin one-week ATM IV gap between Solana and Bitcoin widened 4.09 volatility points to 27.32 volatility points over the observation window, reaching the 87.5 percentile of the available historical comparison set. ATM IV is the implied volatility of at-the-money options, a measure of the volatility priced into contracts near the prevailing price.\n\nDerivasys data show Solana as the high end and Bitcoin as the low end of this one-week ATM IV comparison. One-week implied-versus-realised volatility data were unavailable for Bitcoin, Ether and Solana, and no qualifying news context was retained.",
  "marketSummary": "Derivasys data showed one-week ATM IV level dispersion of 27.32 volatility points between Solana and Bitcoin, after the Solana-versus-Bitcoin spread widened 4.09 volatility points. The one-week ATM IV change dispersion was 4.25 volatility points, spanning Solana’s 1.23-volatility-point rise and Ether’s 3.02-volatility-point decline.",
