Bitcoin topped $77,000 on Aug 21, 2026, posting its best week since 2023. CoinGecko data put BTC near $77,917, up about 5.8% in 24 hours as of 01:00 UTC Aug 22. During the session BTC briefly approached $80,000 before slipping back toward $77,000 on thinner weekend liquidity. The move followed the US Treasury's plan to double its debt buyback operations to $4B from Sept 9, adding to expectations of looser macro liquidity. Altcoins tracked the rally higher, with XRP and others posting strong weekly gains.
