=====================================
Bitcoin Block Halving prediction
=====================================
bc=963759
gbt=1231006505
bbt=1787509876
This is average time to mine a block
(1787509876-1231006505)/963759
bts=577.4294129243795135718436
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 03:19:26 UTC 2028
-------------------------------------
Next palindrome will be 964469
predicted to happen at this time:
Fri Aug 28 12:24:10 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
