=====================================
Bitcoin Block Halving prediction
=====================================
bc=958447
gbt=1231006505
bbt=1784317639
This is average time to mine a block
(1784317639-1231006505)/958447
bts=577.2990647379930888269368
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 13:18:20 UTC 2028
-------------------------------------
Next palindrome will be 958859
predicted to happen at this time:
Mon Jul 20 13:51:26 UTC 2026
-------------------------------------
Current mining epoch number is 475.
The next fortnight happens in block
959616 and probably around this time:
Sat Jul 25 15:15:01 UTC 2026
