Bitcoin dominance is drawing renewed attention as on-chain data shows a growing share of coins remaining untouched for a decade or more. The supply of Bitcoin held for 10 years or longer has reached an all-time high of 17.7% of total supply, encompassing 16.75 million coins. The broader market backdrop remains mixed, with institutional flows yet to fully recover after a prolonged lull.
Galaxy Research director Alex Thorn said these long-standing coins appear “firmly locked” as holders refuse to sell despite price levels near their estimated cost basis. He estimated the average cost basis for these long-term holders at $50,000. Therefore, realized supply at this level has not meaningfully loosened.
As a result, actual circulating supply may be tighter than headline figures imply. This dynamic supports narratives that emphasize supply inelasticity. In turn, shorter-term traders may face thinner order books when volatility rises.
Meanwhile, short-term activity has softened, even as headline flows show a modest uptick. After eight consecutive weeks of outflows, U.S. spot Bitcoin ETFs recorded $197.4 million in net inflows. However, the 30-day fund flow momentum remains deeply negative at -$4.73 billion, signaling that institutional demand has not fully recovered.
By contrast, the accumulation profile among long-term investors has introduced a supply dynamic that could dampen immediate liquidity. As coins age into the 10-year-plus cohort, fewer units appear available for sale on exchanges. Therefore, day-to-day market depth may be increasingly influenced by a smaller pool of active supply.
Bitcoin dominance and holder composition
Notably, the rise in decade-old holdings adds a structural layer to Bitcoin dominance discussions centered on supply inelasticity. These data points suggest that a non-trivial fraction of supply is held by participants with strong conviction and long time horizons. In addition, Thorn’s comment that these coins are “firmly locked” underscores reluctance to distribute at current prices.
However, the exact distribution of these long-term holdings across wallets and entities was not disclosed. The emphasis is on the aggregate proportion and the average cost basis near $50,000. Consequently, market observers are watching whether realized spending from this cohort increases if price conditions change.
Institutional flows remain subdued on a trend basis, despite the latest ETF inflow tally. The persistent negative 30-day momentum of -$4.73 billion points to caution among larger allocators. Meanwhile, eight weeks of prior outflows help explain why sentiment has yet to decisively turn.
In addition, the interplay between locked long-term supply and hesitant institutional flows forms a key tension for market structure. If steadfast holders continue to limit available supply, price discovery may hinge on marginal buyers and sellers with shorter horizons. Conversely, sustained negative fund momentum could offset any tightening effects from holder illiquidity.
Key signals to watch for Bitcoin dominance
Therefore, analysts tracking Bitcoin dominance may focus on three signals: the share of coins held for 10+ years, the average cost basis of those long-term wallets, and the 30-day ETF flow momentum. Together, these indicators help frame supply availability versus demand recovery. Notably, the latest readings show elevated long-term holding, a cost basis near $50,000, and a still-negative fund flow trend.
According to the source, these conditions have contributed to a tightening of actual circulating supply. The durability of this dynamic depends on whether long-term holders maintain their stance if market prices fluctuate. Also, any sustained shift in ETF flows could influence liquidity conditions at the margin.
As a result, the current setup reflects a market balancing sturdy holder resolve against tentative institutional participation. Observers will look for confirmation in subsequent weekly flow data and updates to held-for-10-years metrics. Until then, the weight of supply appears concentrated among owners described as reluctant to sell.
