=====================================
Bitcoin Block Halving prediction
=====================================
bc=944409
gbt=1231006505
bbt=1775783016
This is average time to mine a block
(1775783016-1231006505)/944409
bts=576.8432259294162492985038
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 00:21:09 UTC 2028
-------------------------------------
Next palindrome will be 944449
predicted to happen at this time:
Fri Apr 10 07:28:09 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 08:30:59 UTC 2026
