=====================================
Bitcoin Block Halving prediction
=====================================
bc=940074
gbt=1231006505
bbt=1773124363
This is average time to mine a block
(1773124363-1231006505)/940074
bts=576.6751142196101374890301
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 23:19:11 UTC 2028
-------------------------------------
Next palindrome will be 941149
predicted to happen at this time:
Tue Mar 17 10:44:48 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Thu Mar 19 14:29:14 UTC 2026
