=====================================
Bitcoin Block Halving prediction
=====================================
bc=926497
gbt=1231006505
bbt=1764913527
This is average time to mine a block
(1764913527-1231006505)/926497
bts=576.2635450913007907194618
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 7 23:16:43 UTC 2028
-------------------------------------
Next palindrome will be 926629
predicted to happen at this time:
Sat Dec 6 02:53:13 UTC 2025
-------------------------------------
Current mining epoch number is 459.
The next fortnight happens in block
927360 and probably around this time:
Wed Dec 10 23:54:02 UTC 2025
