According to the source, a claim is circulating that BTC’s market capitalization ranks above the GDP of most countries; traders should validate this by comparing live BTC market capitalization from CoinMarketCap or Bloomberg with nominal GDP rankings from the IMF World Economic Outlook and World Bank World Development Indicators, noting that GDP measures annual output while market cap reflects aggregate asset value (sources: CoinMarketCap, Bloomberg, IMF WEO, World Bank WDI). For trading impact, institutional participation and market depth can be assessed via CME Bitcoin futures open interest and US spot Bitcoin ETF assets reported by CME Group and issuers such as iShares and Fidelity, which inform liquidity, execution size, and spread conditions; risk calibration can be guided by BTC dominance and realized volatility from TradingView and Glassnode to align position sizing with macro-sensitive flows (sources: CME Group, iShares, Fidelity, TradingView, Glassnode).
