=====================================
Bitcoin Block Halving prediction
=====================================
bc=965466
gbt=1231006505
bbt=1788519311
This is average time to mine a block
(1788519311-1231006505)/965466
bts=577.4540258755607389998829
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 10:30:09 UTC 2028
-------------------------------------
Next palindrome will be 965569
predicted to happen at this time:
Sat Sep 5 03:26:28 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
Sat Sep 5 18:40:46 UTC 2026
