When Will the 20 Millionth Bitcoin Be Mined?

Just for fun I asked ChatGPT, and this was the output. Can anyone verify this?

Let’s estimate when 20 million Bitcoins will be mined, given the following details:

  • Current supply: 19,717,418.75 BTC
  • Remaining BTC to reach 20 million: 282,581.25 BTC
  • Current block reward: 3.125 BTC
  • Blocks mined per day: 144 (since one block is mined approximately every 10 minutes)
  • BTC mined per day: 144 blocks/day * 3.125 BTC/block = 450 BTC/day

Time to Mine Remaining Bitcoins:

  • Days to mine 282,581.25 BTC: 282,581.25 BTC / 450 BTC/day ≈ 628 days

Estimated Date Calculation:

  • Current date: June 26, 2024
  • Days to mine 282,581.25 BTC: 628 days

Adding 628 days to June 26, 2024, gives us the estimated date:

  • Start date: June 26, 2024
  • Adding 628 days:Calculations:
    • June 26, 2024 + 628 days
      • From June 26, 2024 to December 31, 2024: 188 days
      • Remaining days: 628 – 188 = 440 days
      • Adding 440 days to January 1, 2025: 365 days to December 31, 2025, and 75 days into 2026

So, approximately:

  • Estimated date: March 16, 2026

Time in Singapore:

Singapore is 8 hours ahead of UTC. Assuming a mid-day time estimate in UTC:

  • Estimated date and time in UTC: March 16, 2026, 12:00 PM
  • Singapore time: March 16, 2026, 8:00 PM

Final Estimate:

Estimated Date and Time in Singapore: March 16, 2026, at 8:00 PM

This estimate assumes constant mining rate and no significant changes in mining difficulty or network conditions.
