Bitcoin chart of the day My read: $84,500 is the first test. Bitview's model price for 28 September UTC ended near $83,280, below the $84,502 active price and the $84,681 long holder acquisition benchmark. The active price adjusts realized price for how much accumulated holding time has been spent. At the same snapshot, Bitview's Coinflow model put about 40.6% of supply statistically likely to move in the next 30 days in loss, up from about 33.6% the previous day. That is potential sell side sensitivity, not a forecast that those coins will sell. I want to see model price reclaim the active line before treating the bounce as convincing. These are model estimates, not exchange prints or guaranteed resistance.

Bitcoin chart of the day My read: the ETF bid has not disappeared, but its pace faded every day last week. US spot Bitcoin funds took in $999m on Monday and $134.5m on Friday, according to The Block's SoSoValue tally. Bitview's model price for 27 September UTC is about $84,267, still below the long holder acquisition level near $84,683. That is the test this week: does new fund demand pick up enough to help price reclaim the holder benchmark? The flow figures are an aggregator tally, and today's US fund flow is not in yet. Levels are model estimates, not exchange prints.

Bitcoin chart of the day My read: $84,700 is the holder hurdle. Bitview's model spot ended 26 September at $84,159, below the $84,697 long holder capitalized price. The all supply benchmark sits at $82,142. A sustained move back above the long holder level would make the rally more convincing. Until then, the price sits between two acquisition benchmarks, and neither one is a guaranteed support or resistance level. These are estimates from unspent output history, not exchange prints.

Bitcoin chart of the day The quarterly expiry is behind us, and the October book is easier to read. At Deribit, the $90k call strike carries 19.7k BTC of open interest and $95k carries 23.3k. The $85k calls are much smaller at 2.7k BTC, but $85k is the nearer test with the index around $83.9k. My read: a move through $85k would put those larger October strikes back in view. Until then, they are positioning, not a forecast. Open interest says nothing by itself about which side dealers hold.

Mandibles vibes rising

Bitcoin chart of the day Something worth flagging from the on-chain data. On 22 Sep, right as BTC pushed to $86k, old coins moved in size. Coinblocks destroyed hit 5.1B that day, about 3.3x the 60-day median and the biggest print since late July. It's still running above normal. That's long-held supply using the rally as exit liquidity. And price has noticed: we closed 23 Sep at $84.3k, just under the 75th-percentile cost basis at $84.6k. My read: this is either a one-off reshuffle (a custodian moving coins does this) or the start of real distribution. The next few days will tell us. If spending drops back toward ~1.5B a day and we reclaim $89k, it was digestion and the breakout is intact. If spending stays hot and we lose $81.2k, the old hands are distributing and I'd expect a longer range. Levels, not predictions.

Bitcoin chart of the day The $90k gate. Spot ~$88.7k. Right overhead: ~9.5k BTC of Sep 25 Deribit call OI at $90k, and on-chain cost basis at $89.1k (80th pct of UTXOs). Next up are the STH 90th pct valuation at $92.6k and the 85th pct UTXO cost basis at $95.5k. Estimated dealer gamma is still positive (~+$470M, flip ~$72k), so dealers likely sell the first push into $90k. That's a model estimate, not observed dealer inventory. What would make it a squeeze: acceptance above ~$92.5k with futures OI falling, funding staying contained and spot ETF inflows. Then $100k is the next call magnet. A daily close below $85k breaks the setup. Zones, not targets. Not advice. Data: Bitview/BRK on-chain, RetailInterest (derived Deribit gamma), Deribit OI via Bitcoin.com
