=====================================
Bitcoin Block Halving prediction
=====================================
bc=951884
gbt=1231006505
bbt=1780255445
This is average time to mine a block
(1780255445-1231006505)/951884
bts=577.0118659291826218503285
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 17 01:32:21 UTC 2028
-------------------------------------
Next palindrome will be 952259
predicted to happen at this time:
Wed Jun 3 07:30:24 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Fri Jun 12 01:18:52 UTC 2026
