=====================================
Bitcoin Block Halving prediction
=====================================
bc=964613
gbt=1231006505
bbt=1788033141
This is average time to mine a block
(1788033141-1231006505)/964613
bts=577.4606588749489433078931
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 12:26:14 UTC 2028
-------------------------------------
Next palindrome will be 965569
predicted to happen at this time:
Sat Sep 5 05:13:13 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
Sat Sep 5 20:27:32 UTC 2026
