Bitcoin Rangebound as Altcoin Rotation Heats Up

Bitcoin (BTC) has been trading in a tight range between $77,100 and $81,300 for the past 20 sessions, with most recent activity concentrated near the middle of this range. The $77,100 level is now key support, marking one of Bitcoin's highest-volume trading levels of 2026, where BTC broke down in May. A drop below could weaken the medium-term uptrend, while a break above $81,300 could quickly push Bitcoin toward $86,500.

Despite little trading between $81,300 and $86,500, creating a potential 'volume vacuum,' selling pressure has been well absorbed, with an aggregate Spent Output Profit Ratio near 1.002 indicating Bitcoin is broadly changing hands around break-even. About 69%-71% of Bitcoin's supply is in profit, still below the 74.7% level that has historically signaled a shift from bear to bull market.

This suggests the current move remains a bear-market relief phase until this threshold is decisively crossed. Meanwhile, XRP, Solana (SOL), and Dogecoin have joined an altcoin rotation, with all 29 of the largest liquid crypto pairs gaining between Sept. 1 and Sept. 8, delivering a median return of 10.2% compared to Bitcoin's 1.4% gain.
