Bitcoin runs on a schedule. Every 10 minutes, a new block. Every four years, the mining reward cuts in half. The last bitcoin will be mined around the year 2140. I built mmcxl.org to show the whole timeline on one page. Halving dates. Historical milestones. Why that 2140 cutoff matters. No signup. No ads. Just the story of digital scarcity unfolding block by block. mmcxl.org
