Bitcoin recorded the largest weekly dollar gain in its history and its biggest percentage gain since March 2023, according to Galaxy Research data shared by Cointelegraph. As of August 28, 2026, Bitcoin trades near $80,455, up 2.0% over 24 hours and about 9.1% across the past seven days.
The dollar figure is the headline. Because Bitcoin's market capitalization is far larger than it was during past rallies, a single-digit percentage week now moves more total dollars than the triple-digit percentage weeks of earlier cycles. A 9% move on a roughly $1.6 trillion asset adds more notional value than a 40% move did when Bitcoin was worth a fraction of that. That is the mechanical reason this week set a record in dollar terms even though the percentage gain, while large, is not close to Bitcoin's biggest ever.
The move was broad, not Bitcoin-only
This was not an isolated Bitcoin bid. The rest of the majors ran harder on a percentage basis. Solana leads the pack, up 8.7% over 24 hours and 24.3% on the week to $109.87. XRP is up 2.95% on the day and 14.3% on the week at $1.45. Ether sits at $2,514 (up 7.3% over seven days) and BNB at $713.51 (up 8.7% on the week).
When the whole board turns green together and the smaller majors outrun Bitcoin, it usually signals risk appetite returning across the market rather than a single-asset catalyst. Traders rotating down the cap curve into Solana and XRP is a classic sign of a market where fear has flipped to greed.
Sentiment has swung to extreme greed
The CoinMarketCap Fear and Greed Index reads 82 out of 100, firmly in "extreme greed" territory. That number matters as much as the price. Extreme greed readings tend to cluster near local tops, not bottoms, because they mark the point where late buyers pile in and leverage builds up.
We have flagged this pattern before. Prior extreme greed spikes have preceded sharp pullbacks, and readings in the low 80s have historically coincided with crowded positioning. None of that guarantees a reversal, but it is the context a reader should hold alongside the record-gain headline. A market posting its largest dollar week in history at an 82 greed reading is running hot.
Record dollar gains raise the leverage question
The other side of a fast rally is what happens to leveraged traders. Rapid upward moves squeeze short sellers and force liquidations, which can accelerate the climb, and the same mechanism works in reverse when the move stalls. Open interest and funding rates typically spike during weeks like this, setting up the conditions for a violent unwind if sentiment turns.
For anyone spending crypto rather than trading it, the practical takeaway is narrower. A stronger Bitcoin and a greed-driven altcoin rally can raise the fiat value of a balance held on a crypto card, but volatility cuts both ways. Cards that let you spend from a stablecoin balance rather than a volatile one insulate day-to-day purchases from swings like this week's. If your goal is to lock in gains from a run like this, stablecoin spending options let you convert the upside without moving to a bank, while cashback rewards accrue independent of which way the market moves next.
The record in context
Galaxy Research's framing, a record dollar gain paired with the largest percentage gain since March 2023, is precise and worth keeping straight. The dollar record reflects Bitcoin's sheer size today. The percentage figure is the more comparable measure across cycles, and by that yardstick this is a strong week but not a historic one. Both things are true at once, and conflating them is how "biggest ever" headlines get overstated.
The number to watch from here is not the price but the positioning behind it. A market that just booked its largest dollar week on record, with sentiment at 82 and the smaller majors up double digits, has priced in a lot of optimism. Whether that holds depends on whether spot demand keeps pace with the leverage that tends to build during moves like this.
Overview
Bitcoin posted its largest weekly dollar gain on record and its biggest percentage gain since March 2023, per Galaxy Research, trading near $80,455 as of August 28, 2026. The rally was broad: Solana rose 24% on the week, XRP 14%, with Ether and BNB up mid-to-high single digits. The Fear and Greed Index reads 82 (extreme greed), a level that has historically preceded pullbacks. The dollar record reflects Bitcoin's size today more than an unusually large percentage move, and the leverage building during fast rallies is the main risk to watch.
