=====================================
Bitcoin Block Halving prediction
=====================================
bc=942219
gbt=1231006505
bbt=1774479731
This is average time to mine a block
(1774479731-1231006505)/942219
bts=576.8007747659782216467491
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 11:58:15 UTC 2028
-------------------------------------
Next palindrome will be 942249
predicted to happen at this time:
Thu Mar 26 03:50:35 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
Fri Apr 3 10:21:31 UTC 2026
