=====================================
Bitcoin Block Halving prediction
=====================================
bc=926089
gbt=1231006505
bbt=1764641341
This is average time to mine a block
(1764641341-1231006505)/926089
bts=576.2235160729518729281171
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 7 11:36:13 UTC 2028
-------------------------------------
Next palindrome will be 926629
predicted to happen at this time:
Fri Dec 5 16:35:01 UTC 2025
-------------------------------------
Current mining epoch number is 459.
The next fortnight happens in block
927360 and probably around this time:
Wed Dec 10 13:35:21 UTC 2025
