Bitcoin Mining Surpasses 20 Million Coins As Foundry USA Hits Milestone Block 939,999

On a recent Sunday, Bitcoin miners pushed total issuance past 20 million BTC, marking roughly 95.24% of the eventual 21 million-coin cap. Foundry USA mined the milestone block at height 939,999, earning a 3.125 BTC reward under the April 2024 halving, while analysts estimate 2.3–3.7 million coins are permanently lost and the final satoshi may not be produced until around 2140. With Bitcoin trading near $69,282 and the next halving set for April 11, 2028, miners face a long-term challenge as block rewards continue shrinking toward near-zero and fee income becomes their primary revenue source.
