=====================================
Bitcoin Block Halving prediction
=====================================
bc=958434
gbt=1231006505
bbt=1784305165
This is average time to mine a block
(1784305165-1231006505)/958434
bts=577.2938801274995174424974
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 11:47:36 UTC 2028
-------------------------------------
Next palindrome will be 958859
predicted to happen at this time:
Mon Jul 20 12:28:34 UTC 2026
-------------------------------------
Current mining epoch number is 475.
The next fortnight happens in block
959616 and probably around this time:
Sat Jul 25 13:52:06 UTC 2026
