Bitcoin hits 20M mined, 95% of supply locked—miners watch fee shift
Bitcoin has surpassed 20 million BTC mined, reaching over 95% of the total 21 million supply. The next unlock is small: fewer than 1 million BTC remain, with issuance tapering until around 2140 due to the protocol’s halving schedule.
The milestone 20,000,000th coin was minted around March 9 near block height 940,000 by the Foundry USA mining pool. After the April 2024 halving, issuance is about 450 BTC per day, meaning 95% of Bitcoin took under two decades while the final 5% will take until 2140.
For miners, this reinforces a key trading thesis: block rewards will keep shrinking and revenue will gradually rely more on transaction fees. If fees fail to rise in line with lower rewards, mining may become less profitable, potentially leading to reduced hashrate and broader network-security concerns. The next halving is expected in 2028.
On the market supply side, headline scarcity is now “mostly priced in,” but effective circulating supply may be lower because many of the mined coins are estimated to be permanently lost (e.g., lost keys or inaccessible wallets).

Bullish
Bitcoin reaching 95% of its 21M cap is a scarcity milestone that tends to support the asset’s medium-to-long term narrative. Historically, major Bitcoin supply events (notably halvings) have often coincided with renewed investor focus on reduced new issuance and the long-dated supply-demand imbalance. While this article is not directly about price, it emphasizes the declining issuance rate (post-April 2024 halving ~450 BTC/day) and the shift from block rewards to transaction fees—factors that can affect miner profitability and, indirectly, network security.
Short-term: traders may see limited immediate impact on spot demand because the remaining supply is still small but not “zero.” However, headlines around “20M mined / 95% done” can trigger momentum/positioning flows, particularly if markets interpret it as further confirmation that the scarcity model is functioning as designed.
Medium-to-long term: if transaction fees continue rising as rewards decline, miner revenue stability should improve, supporting hashrate continuity and reducing security risk. If fees do not keep pace, some margin compression could pressure hashrate, but difficulty adjustment and the expectation of another halving in 2028 suggest the network can adapt.
Net: scarcity confirmation plus the ongoing trajectory of lower issuance typically skews toward bullish sentiment for BTC, with the main risk being miner economics and fee growth not matching the reward decline.
