=====================================
Bitcoin Block Halving prediction
=====================================
bc=925167
gbt=1231006505
bbt=1764108121
This is average time to mine a block
(1764108121-1231006505)/925167
bts=576.2214170831675976687477
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 7 10:59:29 UTC 2028
-------------------------------------
Next palindrome will be 925529
predicted to happen at this time:
Fri Nov 28 07:58:33 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
Thu Nov 27 02:21:52 UTC 2025
