=====================================
Bitcoin Block Halving prediction
=====================================
bc=965080
gbt=1231006505
bbt=1788293899
This is average time to mine a block
(1788293899-1231006505)/965080
bts=577.4514201398639077963404
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 09:44:33 UTC 2028
-------------------------------------
Next palindrome will be 965569
predicted to happen at this time:
Sat Sep 5 02:44:32 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
Sat Sep 5 17:58:50 UTC 2026
