=====================================
Bitcoin Block Halving prediction
=====================================
bc=940723
gbt=1231006505
bbt=1773548131
This is average time to mine a block
(1773548131-1231006505)/940723
bts=576.7277394857577780517984
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 14:40:08 UTC 2028
-------------------------------------
Next palindrome will be 941149
predicted to happen at this time:
Wed Mar 18 00:30:17 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Fri Mar 20 04:15:00 UTC 2026
