Bitcoin regains $81,000 level

BTC trading back above 81,000 signals a near-term improvement in crypto risk appetite and positioning, potentially triggering momentum re-engagement and short-covering across majors. While the update is price-action driven rather than fundamentally new information, it can tighten liquidity conditions for bearish bets and lift broad market beta, with spillover sensitivity into high-volatility altcoins and crypto-linked equities.
