=====================================
Bitcoin Block Halving prediction
=====================================
bc=922598
gbt=1231006505
bbt=1762518084
This is average time to mine a block
(1762518084-1231006505)/922598
bts=576.1024876463122114808275
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 6 00:18:13 UTC 2028
-------------------------------------
Next palindrome will be 923329
predicted to happen at this time:
Wed Nov 12 09:20:14 UTC 2025
-------------------------------------
Current mining epoch number is 457.
The next fortnight happens in block
923328 and probably around this time:
Wed Nov 12 09:10:38 UTC 2025
