=====================================
Bitcoin Block Halving prediction
=====================================
bc=961374
gbt=1231006505
bbt=1786078699
This is average time to mine a block
(1786078699-1231006505)/961374
bts=577.3732352099856975685866
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 10:56:19 UTC 2028
-------------------------------------
Next palindrome will be 962269
predicted to happen at this time:
Thu Aug 13 04:30:48 UTC 2026
-------------------------------------
Current mining epoch number is 476.
The next fortnight happens in block
961632 and probably around this time:
Sat Aug 8 22:21:01 UTC 2026
