Methodology

How this estimate works

Bitcoin halves its block subsidy every 210,000 blocks. The calculator multiplies blocks remaining by your average block-time assumption. It does not predict the exact date because real block intervals vary.

A lower issuance rate does not guarantee a higher Bitcoin price. Demand, liquidity, regulation, macro conditions and market expectations still matter.
