=====================================
Bitcoin Block Halving prediction
=====================================
bc=967776
gbt=1231006505
bbt=1789867017
This is average time to mine a block
(1789867017-1231006505)/967776
bts=577.4682721329397164842727
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 14:39:28 UTC 2028
-------------------------------------
Next palindrome will be 968869
predicted to happen at this time:
Sun Sep 27 08:36:29 UTC 2026
-------------------------------------
Current mining epoch number is 480.
The next fortnight happens in block
969696 and probably around this time:
