=====================================
Bitcoin Block Halving prediction
=====================================
bc=958031
gbt=1231006505
bbt=1784042934
This is average time to mine a block
(1784042934-1231006505)/958031
bts=577.2630026971959182991799
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 02:47:15 UTC 2028
-------------------------------------
Next palindrome will be 958859
predicted to happen at this time:
Mon Jul 20 04:15:07 UTC 2026
-------------------------------------
Current mining epoch number is 475.
The next fortnight happens in block
959616 and probably around this time:
Sat Jul 25 05:38:15 UTC 2026
