=====================================
Bitcoin Block Halving prediction
=====================================
bc=939764
gbt=1231006505
bbt=1772915957
This is average time to mine a block
(1772915957-1231006505)/939764
bts=576.6435779157555346283379
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 14:07:18 UTC 2028
-------------------------------------
Next palindrome will be 939939
predicted to happen at this time:
Mon Mar 9 00:41:09 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Thu Mar 19 06:14:24 UTC 2026
