=====================================
Bitcoin Block Halving prediction
=====================================
bc=964104
gbt=1231006505
bbt=1787727124
This is average time to mine a block
(1787727124-1231006505)/964104
bts=577.4481192401242603243422
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 08:46:47 UTC 2028
-------------------------------------
Next palindrome will be 964469
predicted to happen at this time:
Fri Aug 28 17:24:52 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
