=====================================
Bitcoin Block Halving prediction
=====================================
bc=931573
gbt=1231006505
bbt=1767978514
This is average time to mine a block
(1767978514-1231006505)/931573
bts=576.4136923100043582152357
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 9 19:04:18 UTC 2028
-------------------------------------
Next palindrome will be 932239
predicted to happen at this time:
Wed Jan 14 03:46:45 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Wed Jan 21 22:57:13 UTC 2026
