=====================================
Bitcoin Block Halving prediction
=====================================
bc=971880
gbt=1231006505
bbt=1792250790
This is average time to mine a block
(1792250790-1231006505)/971880
bts=577.4825158635676590035199
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 18:48:44 UTC 2028
-------------------------------------
Next palindrome will be 972279
predicted to happen at this time:
Tue Oct 20 07:26:45 UTC 2026
-------------------------------------
Current mining epoch number is 482.
The next fortnight happens in block
973728 and probably around this time:
Thu Oct 29 23:52:57 UTC 2026
