=====================================
Bitcoin Block Halving prediction
=====================================
bc=938570
gbt=1231006505
bbt=1772191041
This is average time to mine a block
(1772191041-1231006505)/938570
bts=576.6047917525685323752811
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 02:48:32 UTC 2028
-------------------------------------
Next palindrome will be 938839
predicted to happen at this time:
Sun Mar 1 06:22:27 UTC 2026
-------------------------------------
Current mining epoch number is 465.
The next fortnight happens in block
939456 and probably around this time:
Thu Mar 5 09:11:52 UTC 2026
