Bitcoin ($BTC) Technical Update: Defending $80,000 After the $84,840 Rejection

Bitcoin is trading around $80,250 today (Sunday, October 25), after a volatile week that reminded everyone how quickly sentiment can flip when ETF flows shift.

Early in the week, three straight days of US spot Bitcoin ETF inflows totaling $1.08 billion pushed BTC from $81,100 on Tuesday to a local high of $84,840 on Wednesday, October 21. That momentum stalled on Thursday when spot ETFs recorded $635.5 million in net outflows, followed by another $137.9 million in outflows on Friday. The pullback flushed leveraged longs across the market and dragged BTC down to a Saturday low of $79,120 before buyers stepped in to close the daily candle back at $80,772.

Right now, Bitcoin dominance sits near 59.4% with 24-hour spot volume around $19.1 billion. Here are the three levels that matter for the week ahead:

1. Immediate Support ($79,100 to $80,000). Bulls defended the $79,120 wick on Saturday and held $80,000 through Sunday morning. As long as daily candles close above $79,500, this pullback remains a standard range retest rather than a structural breakdown. A clean daily close below $79,000 would open the door toward the $76,500 liquidity zone.

2. Mid-Range Pivot ($81,900 to $82,500). This was the breakdown shelf from October 22 and October 23. For bulls to regain short-term control, BTC needs to reclaim $82,000 on rising spot volume rather than thin weekend perp squeezes.

3. Major Resistance ($84,300 to $84,840). The October 21 peak remains the ceiling to beat. Breaking and holding above $84,840 puts the upper $80,000s back in play.

How to approach it: Monday's US spot ETF flow numbers will likely set the tone for whether $80,000 holds. Keep leverage low on Sunday night, let the Monday session confirm direction around the $80,000 and $82,000 boundaries, and always size positions around a clear invalidation level.
