Bitcoin has recovered to roughly $83,500, but the move has not yet answered a more important market question: is demand strong enough to absorb the supply that could emerge around current prices? A Glassnode framework focused on the cost basis of Bitcoin held closest to spot offers one way to examine that question, while the Federal Reserve’s upcoming meeting could influence the demand backdrop.
According to CryptoSlate, Glassnode’s October 20 analysis highlights proximity-weighted cost basis, a measure designed to give greater importance to on-chain cost bases near Bitcoin’s current trading price. The approach is intended to distinguish between broad market profitability and the specific inventory that may create support or resistance during a recovery.
Why nearby cost bases matter
Bitcoin can return to a similar price level under very different supply conditions. If a larger share of the relevant weighted supply has a cost basis below spot than during an earlier visit, the price may be supported by holders who are already profitable or near breakeven. If more of that supply sits above spot, the same level may face greater resistance as holders approach their cost basis.
This distinction matters because aggregate profitability does not reveal where the underlying cost bases are located. Glassnode’s October 19 market report said 68.2% of Bitcoin’s supply was in profit, while spot buying remained weak during the period covered. That combination shows how a large share of profitable supply can coexist with limited immediate demand.
The familiar market value to realized value ratio, or MVRV, compares Bitcoin’s market capitalization with realized capitalization, which is based on the value of coins when they last moved on-chain. NUPL, or net unrealized profit and loss, presents the difference between those two measures as a share of market capitalization. Both describe the relationship between market value and an aggregate cost-basis reference, but neither alone identifies the supply nearest to the current price.
How the proximity framework works
The proximity method divides Bitcoin’s cost-basis distribution into percentile groups and assigns larger weights to groups closer to spot. Those weights decline exponentially with distance, with the distance adjusted using Bitcoin’s 30-day rolling price volatility.
That volatility adjustment is important when interpreting changes. With spot and individual cost bases unchanged, higher volatility spreads meaningful weight across a wider price range, while lower volatility concentrates the measure more tightly around the market price. As a result, a change in the proximity measure can reflect price, volatility or a shift in the underlying distribution.
Proximity MVRV is calculated by dividing spot price by the proximity-weighted realized price. A value of one means the two are equal; a value above one means spot is higher than the weighted reference. Proximity NUPL expresses the same relationship as the difference between spot and that reference divided by spot, with zero serving as its breakeven level.
The framework therefore needs to be read in context. A smaller apparent profit cushion may partly result from reducing the influence of distant, low-cost supply rather than from a deterioration in the entire market’s position. Individual holders may also make different selling decisions even when their coins fall into the same modeled cost-basis group.
What would confirm stronger support
Glassnode’s Proximity Support Index measures the share of proximity-weighted supply below Bitcoin’s spot price. Its complementary Resistance Index covers supply at or above spot. Within the model, a support share above 50% indicates a distribution tilted toward support rather than resistance.
These indicators describe potential pressure, not guaranteed buying or selling. On-chain prices associated with coin movements are an imperfect proxy for an owner’s actual acquisition cost, and holders do not necessarily offer coins for sale when the market reaches a particular level. Supply above spot may become relevant only if the price advances toward it.
For that reason, a move above a modeled reference and a subsequent retest provide different information. The initial rally changes Bitcoin’s position relative to the cost-basis distribution. A retest, combined with evidence of actual spot buying, can help show whether buyers are absorbing coins as they become available.
A more constructive support signal would involve improving proximity positioning at comparable prices and visible buyer absorption. By contrast, repeated failed retests, a nearby distribution weighted toward resistance and weak spot demand would undermine the idea that the recovery has established a durable base.
The Fed meeting adds a demand variable
The Federal Reserve’s scheduled Federal Open Market Committee meeting on October 27–28 is another factor that could affect the test. Expectations surrounding interest rates can change before a policy decision and may influence the returns available on cash, borrowing costs and the relative appeal of other investments.
If markets expect lower cash returns or easier financing conditions, demand may have an easier time absorbing available Bitcoin supply, all else equal. Expectations of higher cash returns or more expensive financing could make that absorption more difficult. The market reaction would also depend on what investors had already priced in and on other flows.
The central issue for Bitcoin near $83,000 is therefore not simply whether the rebound continues. It is whether the nearby cost-basis structure becomes more supportive while buyers demonstrate that they can absorb offered supply, particularly as interest-rate expectations evolve.
