=====================================
Bitcoin Block Halving prediction
=====================================
bc=938994
gbt=1231006505
bbt=1772451044
This is average time to mine a block
(1772451044-1231006505)/938994
bts=576.6213227972459917251955
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 07:37:50 UTC 2028
-------------------------------------
Next palindrome will be 939939
predicted to happen at this time:
Sun Mar 8 18:52:31 UTC 2026
-------------------------------------
Current mining epoch number is 465.
The next fortnight happens in block
939456 and probably around this time:
Thu Mar 5 13:30:43 UTC 2026
