=====================================
Bitcoin Block Halving prediction
=====================================
bc=952884
gbt=1231006505
bbt=1780945985
This is average time to mine a block
(1780945985-1231006505)/952884
bts=577.1310074143259679814458
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 18 12:17:19 UTC 2028
-------------------------------------
Next palindrome will be 953359
predicted to happen at this time:
Thu Jun 11 23:22:02 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Sat Jun 13 08:52:22 UTC 2026
