=====================================
Bitcoin Block Halving prediction
=====================================
bc=952261
gbt=1231006505
bbt=1780525225
This is average time to mine a block
(1780525225-1231006505)/952261
bts=577.0667316347811841699028
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 17 17:32:30 UTC 2028
-------------------------------------
Next palindrome will be 953359
predicted to happen at this time:
Thu Jun 11 06:20:44 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Fri Jun 12 15:50:51 UTC 2026
