Sleeping Giants — Dormant BTC & ETH Wallets

Large addresses that have held their balance untouched for years. Some are exchange cold storage that simply doesn't move often. Others are Satoshi-era miner wallets, lost-key vaults, or anonymous early adopters whose return to activity makes the news. Below is our full list of tracked addresses with at least one year of dormancy, sorted by length of inactivity. Use the filter controls in the live page to narrow to three-, five-, or ten-year dormancy thresholds.

Why dormant wallets matter

Approximately 1.75 million BTC sit in addresses that have been inactive for over a decade — a meaningful fraction of supply that is effectively out of circulation. Some of this is permanently lost (forgotten keys, broken paper wallets); the rest is held by long-term believers, early miners, or entities that prefer cold storage to active trading. Chainalysis research suggests around 1.5 million BTC may be permanently lost. When one of these wallets unexpectedly moves, the market notices: a coin that has been sitting since 2010 suddenly hitting an exchange address is interpreted differently from a routine cold-wallet rebalance, and the answer often shapes short-term sentiment.

Dormant Bitcoin Wallets (14 addresses, 1.79M BTC)

USD values calculated at a reference price of $95.0K per BTC; live prices replace these once the page loads. Balances refreshed daily from public blockchain APIs. Cluster rows (badged RESEARCH ESTIMATE, DISCLOSED HOLDINGS, or SEIZED HOLDINGS) are aggregate figures across multiple custody addresses, not single-address balances.

Dormant Ethereum Wallets (4 addresses, 80.00M ETH)

USD values calculated at a reference price of $3.3K per ETH; live prices replace these once the page loads. Balances refreshed daily from public blockchain APIs. Cluster rows (badged RESEARCH ESTIMATE, DISCLOSED HOLDINGS, or SEIZED HOLDINGS) are aggregate figures across multiple custody addresses, not single-address balances.

How dormancy is measured

Dormancy is measured from the wallet's last outbound transaction — the moment it last sent funds out, not the moment it last received them. This is an important distinction. An address can continue to receive deposits indefinitely while still being considered dormant, because the entity controlling the private keys has not demonstrated activity. Some of the largest dormant wallets continue to receive donations or accidental transfers years after their owners stopped using them, and the dormancy clock keeps running regardless. The wallets that have never spent a single satoshi — including the MtGox hack address and several early Satoshi-era miner wallets — represent the most extreme end of the dormancy distribution.

The four dormancy tiers and what they mean

We bucket dormant wallets into four conventional tiers because each tier carries a different analytical weight. One-year-plus dormancy captures long-term holders and cold-storage rebalances that happen on a multi-year cycle; movement out of this bucket is common and rarely market-moving. Three-year-plus dormancy starts to capture genuine HODL behavior — the wallet has survived at least one full crypto market cycle without selling, which is the de facto definition of a committed long-term holder. Five-year-plus dormancy is the threshold at which a wallet's owner has demonstrated patience through multiple cycles and is statistically more likely to be either an institutional cold-storage operation or a lost-key wallet. Ten-year-plus dormancy is where the Satoshi-era and early-adopter wallets live; movement from this bucket is genuinely rare and almost always becomes news.

Reading dormancy in market context

The aggregate dormant supply is one of the most reliable supply-side indicators in cryptocurrency analysis. When the total amount of BTC sitting in long-dormant addresses is growing, it indicates that recent buyers are moving coins into cold storage and reducing effective float. When the total is shrinking — when long-dormant wallets are awakening faster than new ones are joining the dormant cohort — it indicates that committed long-term holders are starting to spend, which historically has correlated with mid-to-late-cycle market tops. The dormant supply curve is therefore not just an interesting statistic but an actionable input for cycle analysis, particularly when combined with the more conventional dormancy metrics like Coin Days Destroyed and HODL Waves that on-chain analytics platforms publish.

Frequently Asked Questions

What is a dormant cryptocurrency wallet?

A dormant wallet is an on-chain address that holds a balance but has not produced an outbound transaction for an extended period — typically at least a year by most analytics conventions, and often considerably longer for the wallets that draw the most attention. Dormancy is measured strictly from the last outbound transaction; inbound deposits do not "wake" a wallet. The longer an address remains dormant, the more analytically significant a sudden movement becomes.

How much Bitcoin is in dormant wallets?

Estimates vary depending on how dormancy is defined. Approximately 1.75 million BTC sit in addresses inactive for over a decade — a meaningful fraction of total circulating supply. Chainalysis research suggests around 1.5 million BTC may be permanently lost to forgotten keys, broken hardware, or deceased owners; the remainder is held by long-term holders who choose not to transact. The exact split between lost and intentionally-held supply is unknowable from on-chain data alone, but the combined dormant supply has a meaningful effect on the effective circulating float available for trading.

What is a Satoshi-era wallet?

Satoshi-era wallets are addresses first funded during the earliest years of Bitcoin — typically 2009 to 2010, before Bitcoin had any meaningful market price. Many were funded directly by mining rewards (50 BTC per block at the time) and have not produced a single outbound transaction since. Whether any of these addresses are controlled by Satoshi Nakamoto himself is unknown and probably unknowable, but the Patoshi pattern — a clustering analysis by researcher Sergio Demian Lerner — suggests that a single dominant early miner accumulated roughly 1.1 million BTC. Some Satoshi-era wallets have awakened in recent years; most remain silent.

Why do dormant wallets matter for the market?

Dormant supply acts as a tailwind for prices to the extent that it is effectively out of circulation. When a long-dormant wallet awakens, the market interprets it as supply re-entering the float, which can create short-term selling pressure if the coins are moved to an exchange. Even when the coins are simply moved between self-custody wallets, the event tends to draw attention and can move prices on sentiment alone. Tracking the dormant cohort is therefore useful both as a supply-side baseline and as an early-warning system for potential supply shocks.

What is the MtGox hack wallet?

The address 1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF received 79,956 BTC stolen from the MtGox exchange on March 1, 2011. Mark Karpelès, the former MtGox CEO, publicly confirmed the origin of these funds in 2023. The wallet has never produced an outbound transaction in the entire history of Bitcoin and remains one of the largest known dormant wallets on the chain. Whoever controls the private keys has held what is now a multi-billion-dollar position for more than a decade without selling — one of the most extreme examples of dormant supply in any market.

Are dormant wallets the same as lost wallets?

No. A dormant wallet is one that simply has not transacted recently; a lost wallet is one whose private keys are unrecoverable, making the funds permanently inaccessible. Every lost wallet appears dormant, but not every dormant wallet is lost. The distinction matters because dormant supply can re-enter circulation at any moment, while lost supply cannot. From an on-chain perspective the two categories are indistinguishable — only the wallet owner knows whether the keys still exist.

How do you decide which wallets to include in the dormant list?

We include any address from our tracking registry that has not produced an outbound transaction in at least one year, sorted by dormancy descending. The filter controls on the page let you raise that threshold to three, five, or ten years to focus on the most consequential addresses. The registry itself is curated for editorial significance — we focus on wallets with large balances, public attribution, or notable history — so the dormant list is a high-signal subset rather than an exhaustive census of every quiet address on the chain.
