=====================================
Bitcoin Block Halving prediction
=====================================
bc=942117
gbt=1231006505
bbt=1774422757
This is average time to mine a block
(1774422757-1231006505)/942117
bts=576.8027487002689684307061
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 12:32:47 UTC 2028
-------------------------------------
Next palindrome will be 942249
predicted to happen at this time:
Thu Mar 26 04:21:34 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
Fri Apr 3 10:52:33 UTC 2026
