Bitcoin’s role in the global macroeconomy is as a decentralized store of value, often dubbed "digital gold." Its fixed 21 million supply contrasts with inflationary fiat currencies, enhancing its safe-haven potential amid economic uncertainty, like the 2023 banking crises when BTC surged 30%. However, its volatility—down 15% in a week during 2024 Fed rate hikes—challenges its reliability versus gold. X posts highlight growing institutional adoption (e.g., BlackRock’s ETF), bolstering its credibility. Still, regulatory risks and energy concerns cap its mainstream appeal, positioning BTC as a partial, not full, safe-haven asset.
