=====================================
Bitcoin Block Halving prediction
=====================================
bc=970855
gbt=1231006505
bbt=1791682807
This is average time to mine a block
(1791682807-1231006505)/970855
bts=577.5071709913725619453348
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 23 02:00:12 UTC 2028
-------------------------------------
Next palindrome will be 971179
predicted to happen at this time:
Tue Oct 13 05:38:39 UTC 2026
-------------------------------------
Current mining epoch number is 481.
The next fortnight happens in block
971712 and probably around this time:
Fri Oct 16 19:08:50 UTC 2026
