=====================================
Bitcoin Block Halving prediction
=====================================
bc=925952
gbt=1231006505
bbt=1764554631
This is average time to mine a block
(1764554631-1231006505)/925952
bts=576.2151275496704476361111
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 7 09:09:25 UTC 2028
-------------------------------------
Next palindrome will be 926629
predicted to happen at this time:
Fri Dec 5 14:25:28 UTC 2025
-------------------------------------
Current mining epoch number is 459.
The next fortnight happens in block
927360 and probably around this time:
