=====================================
Bitcoin Block Halving prediction
=====================================
bc=951595
gbt=1231006505
bbt=1780075947
This is average time to mine a block
(1780075947-1231006505)/951595
bts=576.9984762441204040370073
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 21:38:02 UTC 2028
-------------------------------------
Next palindrome will be 952259
predicted to happen at this time:
Wed Jun 3 03:57:53 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Thu Jun 11 21:46:04 UTC 2026
