=====================================
Bitcoin Block Halving prediction
=====================================
bc=955402
gbt=1231006505
bbt=1782424221
This is average time to mine a block
(1782424221-1231006505)/955402
bts=577.1571954452728325115160
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 18 19:55:37 UTC 2028
-------------------------------------
Next palindrome will be 955559
predicted to happen at this time:
Fri Jun 26 23:00:34 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 03:01:03 UTC 2026
