=====================================
Bitcoin Block Halving prediction
=====================================
bc=934288
gbt=1231006505
bbt=1769740145
This is average time to mine a block
(1769740145-1231006505)/934288
bts=576.6241923002411459409240
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 08:28:03 UTC 2028
-------------------------------------
Next palindrome will be 934439
predicted to happen at this time:
Sat Jan 31 02:40:15 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Fri Feb 6 16:26:30 UTC 2026
