=====================================
Bitcoin Block Halving prediction
=====================================
bc=932636
gbt=1231006505
bbt=1768646676
This is average time to mine a block
(1768646676-1231006505)/932636
bts=576.4731304891399333288299
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 10 12:24:28 UTC 2028
-------------------------------------
Next palindrome will be 933339
predicted to happen at this time:
Thu Jan 22 03:18:56 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Thu Jan 22 14:21:53 UTC 2026
