=====================================
Bitcoin Block Halving prediction
=====================================
bc=965009
gbt=1231006505
bbt=1788252504
This is average time to mine a block
(1788252504-1231006505)/965009
bts=577.4510098340949834716738
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 09:37:22 UTC 2028
-------------------------------------
Next palindrome will be 965569
predicted to happen at this time:
Sat Sep 5 02:37:56 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
Sat Sep 5 17:52:14 UTC 2026
