Bitcoin got through the $85K wall, but the rally is running light.

Our new Week On-chain maps what is missing, what altcoins are doing and the levels to watch.

The US bid that led $BTC has flipped.

From July to the September breakout, US trading hours drove most of Bitcoin's gains. Since then, the US session has been a net seller.

The full picture, from ETF flows to liquidations, in this week's Week On-chain 👇

Bitcoin is moving into support.

After a rejection from the sell wall at $86.5K, $BTC has slid toward multiple large buy orders. The largest sits around $81k.

These bids have been patiently waiting and will help to dampen downside.

Existing holders have been carrying this $BTC rally.

The realized cap keeps climbing while new money from ETFs, stablecoins and treasuries is dropping.

The 2024 and 2025 rallies showed the same gap, but on far larger inflows. A pickup in new money would put real demand behind BTC.

Most #BTC with a visible public key is exposed through address reuse, and that part has been growing.

The balance in reused addresses rose from 3.79M to 4.33M BTC over the past year, and now covers 21.5% of circulating supply.

$BTC has bounced off the ETF cost basis.

Price spent most of this year below that level, and the May rally stalled right under it.

It has now held twice as support around $81.5k. Below it, the next major level is the True Market Mean at $77.5k.

The cost basis of investors that bought the top still caps BTC's upside.

Holders who bought 1 to 2 years ago sold heavily as $BTC rallied toward $88k, where the 6 to 12 month group breaks even. Price stalled just under it.

That selling has since slowed considerably.
