=====================================
Bitcoin Block Halving prediction
=====================================
bc=971399
gbt=1231006505
bbt=1791979348
This is average time to mine a block
(1791979348-1231006505)/971399
bts=577.4890292361540045295449
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 20:42:43 UTC 2028
-------------------------------------
Next palindrome will be 972279
predicted to happen at this time:
Tue Oct 20 09:12:18 UTC 2026
-------------------------------------
Current mining epoch number is 481.
The next fortnight happens in block
971712 and probably around this time:
Fri Oct 16 14:15:02 UTC 2026
