=====================================
Bitcoin Block Halving prediction
=====================================
bc=970905
gbt=1231006505
bbt=1791712739
This is average time to mine a block
(1791712739-1231006505)/970905
bts=577.5082592959565601613338
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 23 02:19:14 UTC 2028
-------------------------------------
Next palindrome will be 971179
predicted to happen at this time:
Tue Oct 13 05:56:16 UTC 2026
-------------------------------------
Current mining epoch number is 481.
The next fortnight happens in block
971712 and probably around this time:
Fri Oct 16 19:26:28 UTC 2026
