=====================================
Bitcoin Block Halving prediction
=====================================
bc=939211
gbt=1231006505
bbt=1772589026
This is average time to mine a block
(1772589026-1231006505)/939211
bts=576.6350099870955652185023
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 11:37:22 UTC 2028
-------------------------------------
Next palindrome will be 939939
predicted to happen at this time:
Sun Mar 8 22:26:56 UTC 2026
-------------------------------------
Current mining epoch number is 465.
The next fortnight happens in block
939456 and probably around this time:
Thu Mar 5 17:05:01 UTC 2026
