=====================================
Bitcoin Block Halving prediction
=====================================
bc=974121
gbt=1231006505
bbt=1793533095
This is average time to mine a block
(1793533095-1231006505)/974121
bts=577.4703681879682421708985
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 15:16:09 UTC 2028
-------------------------------------
Next palindrome will be 974479
predicted to happen at this time:
Tue Nov 3 21:03:49 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Thu Nov 12 07:58:49 UTC 2026
