=====================================
Bitcoin Block Halving prediction
=====================================
bc=896366
gbt=1231006505
bbt=1747029739
This is average time to mine a block
(1747029739-1231006505)/896366
bts=575.6829892220485582356333
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Feb 29 21:56:59 UTC 2028
-------------------------------------
Next palindrome will be 896698
predicted to happen at this time:
Wed May 14 11:07:45 UTC 2025
-------------------------------------
Current mining epoch number is 444.
The next fortnight happens in block
897120 and probably around this time:
Sat May 17 06:36:43 UTC 2025
