=====================================
Bitcoin Block Halving prediction
=====================================
bc=930289
gbt=1231006505
bbt=1767197048
This is average time to mine a block
(1767197048-1231006505)/930289
bts=576.3692429242494275978458
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 9 06:06:26 UTC 2028
-------------------------------------
Next palindrome will be 931139
predicted to happen at this time:
Tue Jan 6 08:09:21 UTC 2026
-------------------------------------
Current mining epoch number is 461.
The next fortnight happens in block
931392 and probably around this time:
Thu Jan 8 00:39:43 UTC 2026
